(Eccentric Adjustment Bolt) — M14</strong>, fitted to the rear lateral link outer mounting position across essentially the entire modern Subaru vehicle range (1998-2025+). Subaru's official catalogue name is <strong>"BOLT CAM"</strong> / "Lateral Arm Bolt". The component is a high-strength M14 cam-headed steel bolt with an eccentric cam profile under the head — rotating the bolt during alignment service moves the lateral link mounting position through a small offset arc, providing adjustment of rear wheel <strong>camber and toe angles</strong>. The 901700154 is a <strong>safety-critical, single-use fastener</strong> requiring replacement after every disassembly — Subaru designates "Part cannot be reused/reinstalled" in official service literature.</p> <div class="qf-info-box"><strong>Cam bolt function and quantity.</strong> Each Subaru rear suspension axle uses <strong>2x 901700154 cam bolts</strong> (left side + right side) at the lateral link outer mounting position. The cam bolt's eccentric profile under the head engages with a corresponding cam plate at the subframe; rotating the bolt before final torquing shifts the lateral link's outer pivot through approximately ±1.5 degrees of camber adjustment and proportional toe adjustment. This is the primary mechanism for rear wheel alignment adjustment on Subaru's multi-link rear suspension architecture (Symmetrical AWD platform). After every disassembly — suspension repair, lateral link replacement, hub bearing service, or alignment correction — both LH and RH cam bolts must be replaced and the rear alignment must be re-set.</div> <div class="qf-spec-row"> <div class="qf-spec-item"><div class="qf-spec-label">Brand part number</div><div class="qf-spec-value">Subaru 901700154</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Subaru catalogue name</div><div class="qf-spec-value">BOLT CAM / Lateral Arm Bolt</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Thread size</div><div class="qf-spec-value">M14 (Subaru "BOLT(L/L OUT)M14" designation)</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Position</div><div class="qf-spec-value">Rear suspension, lateral link outer (LH + RH, 2 per axle)</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Function</div><div class="qf-spec-value">Eccentric cam adjustment — rear camber + toe alignment</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Service designation</div><div class="qf-spec-value">SINGLE-USE — "Part cannot be reused/reinstalled"</div></div> </div> <div class="qf-sub-head">OEM Cross-References</div> <div class="qf-cross-grid"> <div class="qf-cross-card"><div class="qf-cross-brand">Subaru Genuine (current)</div><div class="qf-cross-num">901700154</div><div class="qf-cross-status">✓ Subaru OEM primary reference</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">Subaru Genuine (alternate)</div><div class="qf-cross-num">901700122</div><div class="qf-cross-status">✓ Subaru alternate / supersession reference</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">Subaru Genuine (alternate)</div><div class="qf-cross-num">903120003</div><div class="qf-cross-status">✓ Subaru alternate reference</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">Subaru Engineering Drawing</div><div class="qf-cross-num">#M700154</div><div class="qf-cross-note">Subaru rear suspension diagram reference position</div></div> </div> <div class="qf-sub-head">Operating Principle</div> <p class="qf-para">Subaru's multi-link rear suspension uses a lateral link (transverse arm) controlling wheel position horizontally. The 901700154 cam bolt secures the inner mounting position. The bolt's head assembly incorporates an <strong>eccentric cam profile</strong> — the bolt's effective rotational centre is offset from its geometric centre by approximately 1.5-2 mm. Rotating the bolt in its mounting bore shifts the lateral link mounting position through a small arc.</p> <p class="qf-para">Effect on alignment: <strong>camber adjustment</strong> — lateral movement of inner mounting point changes wheel's vertical inclination; <strong>toe adjustment</strong> — same movement produces secondary effect on wheel pointing angle. Adjustment range is typically <strong>±1.5 degrees camber</strong> per side with proportional toe variation. The cam bolt's adjustment is set during alignment service before final torque.</p> <p class="qf-para">Three failure mechanisms: <strong>(1) corrosion seizure</strong> from road salt / moisture — bolt becomes corrosion-bonded to bushing inner sleeve, often fracturing on attempted removal; <strong>(2) thread damage</strong> from forcing rotation against a seized assembly; <strong>(3) head deformation</strong> from incorrect tool engagement. <strong>Subaru designates the bolt as single-use</strong>: any disassembly produces micro-deformation in the preload zone and surface coating; reusing produces unreliable preload and compromised corrosion protection.</p> </div> </div> </div> <div class="qf-block"> <div class="b-section"> <div class="b-header" onclick="qfToggle('b2')"> <div class="b-title">Symptoms & Diagnostics</div> <div class="b-chevron open" id="qf-chevron-b2">▲</div> </div> <div class="b-body open" id="qf-body-b2"> <div class="qf-symptom"><strong>Rear tyre wear pattern — uneven inside-edge or outside-edge wear on one or both rear tyres</strong> — Rear wheel alignment is outside specification due to loose, damaged, or incorrectly-adjusted cam bolt. Inside-edge wear indicates excessive negative camber; outside-edge wear indicates excessive positive camber. Both rear tyres requiring replacement at half the front tyre mileage = strong indicator of rear alignment fault, often originating at the cam bolt.</div> <div class="qf-symptom"><strong>Rear-end "hunting" feel during cornering or steering instability</strong> — Loose lateral link cam bolt allows excessive lateral link movement under cornering forces, producing inconsistent rear wheel position. Vehicle feels unstable, "wandering", or "loose" in the rear under load transfers. Safety-critical symptom — investigate immediately before tyre wear becomes severe or loss of vehicle control occurs.</div> <div class="qf-symptom"><strong>Audible "clunk" from rear suspension during gear engagement or sudden braking</strong> — Lateral link cam bolt has lost preload and lateral link mounting is moving slightly under sudden load. Clunking sound originates from cam bolt zone. Inspect under-vehicle for loose lateral link with vehicle weight off the suspension via jack.</div> <div class="qf-symptom"><strong>Rear alignment cannot be brought into specification despite cam bolt rotation</strong> — The cam bolt's adjustment range is exhausted and lateral link is at full adjustment endpoint, but alignment remains outside spec. Indicates secondary fault: bent lateral link, damaged subframe, or excessive bushing wear. Replace lateral link bushings and cam bolts simultaneously; persistent failure indicates lateral link replacement or subframe damage.</div> <div class="qf-symptom"><strong>Bolt fractures or rounds-off during attempted removal during routine service</strong> — Corrosion seizure has bonded cam bolt to bushing inner sleeve. Attempted rotation produces head rounding or shank fracture in bore. <strong>Critical</strong>: do NOT continue rotation against a seized bolt; this produces irreparable damage. Apply penetrating fluid and allow extended soak time; if fracture occurs, professional extraction (drilling, stud welding) is required, often with lateral link replacement.</div> <div class="qf-symptom"><strong>Visible corrosion at cam bolt zone — rust streaks or pitting at the cam bolt's head and exposed thread</strong> — Corrosion is actively reducing bolt cross-section and has likely produced internal seizure. Replace at earliest opportunity even if no functional symptoms are present — replacement in advance of failure prevents potential extraction difficulties during eventual service.</div> <div class="qf-info-box"><strong>Diagnosis sequence:</strong> (1) <strong>Tyre wear inspection</strong> — uneven rear tyre wear pattern = primary indicator of rear alignment fault. (2) <strong>4-wheel alignment measurement</strong> — confirm rear camber and toe values vs Subaru OEM specification (varies by model and ride height); out-of-spec rear values = cam bolt service needed. (3) <strong>Visual inspection</strong> at lateral link inner mounting position for bolt head condition, visible corrosion, and cam plate engagement. (4) <strong>Loaded suspension torque check</strong> — with vehicle weight on suspension, attempt loosening test torque on bolt; bolt should not rotate at less than 50% of OEM torque value. (5) <strong>Unload check</strong> — raise vehicle, allow rear suspension to drop, inspect lateral link for any movement / play at the inner mounting position. (6) <strong>Bushing condition</strong> — cam bolt fault often accompanies lateral link bushing failure; inspect bushing for cracking, separation, or visible compression set.</div> </div> </div> </div> <div class="qf-block"> <div class="b-section"> <div class="b-header" onclick="qfToggle('b3')"> <div class="b-title">Logistics & Customs</div> <div class="b-chevron open" id="qf-chevron-b3">▲</div> </div> <div class="b-body open" id="qf-body-b3"> <table class="qf-logistics-table"> <tr><td>International HS Code</td><td>7318.15</td></tr> <tr><td>EAEU Customs Code (TN VED)</td><td>7318 15 900 0</td></tr> <tr><td>Country of Manufacture</td><td>China</td></tr> <tr><td>Quality standard</td><td>IATF 16949</td></tr> <tr><td>Hazardous goods</td><td>No</td></tr> <tr><td>Shipping weight per piece</td><td>0.122 kg (122 grams)</td></tr> <tr><td>Packaging</td><td>Individual sealed bag with part label and corrosion-protective packaging</td></tr> </table> <p style="font-size:12px;color:#888;margin-top:12px;font-style:italic">Threaded fasteners of iron or steel are classified under <strong>HS 7318.15</strong> (other screws and bolts, with or without their nuts or washers).

Re-installation cannot reliably reproduce the original preload; the bolt operates at progressively lower clamp load with each cycle. <strong>(2) Cam profile surface integrity</strong>: the eccentric cam profile under the bolt head has a precision-finished surface that engages with the cam plate; surface scoring during initial torquing eliminates the precision surface, producing inconsistent torque-to-preload relationship on reinstallation. <strong>(3) Corrosion coating breach</strong>: the zinc-flake corrosion coating develops microcracks at the head bearing zone during initial torquing; reusing the bolt exposes these cracks to accelerated corrosion attack.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Why must rear alignment be performed after cam bolt replacement?</div> <div class="qf-faq-a">The cam bolt is the <strong>primary mechanism for rear camber and toe adjustment</strong> on Subaru's multi-link rear suspension. Disturbing the cam bolt invalidates the previous alignment setting — the new bolt cannot be installed at exactly the same cam rotational position as the old bolt without precision measurement equipment. Even with reasonable visual alignment to the original position, the new bolt's installed rotation will produce some shift in rear camber and toe. <strong>Mandatory full 4-wheel alignment service is required after cam bolt replacement</strong> to: (1) verify rear camber and toe are within OEM specification; (2) re-adjust if needed using the new cam bolt's adjustment range; (3) prevent abnormal rear tyre wear that would result from uncorrected alignment offset.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Can the cam bolt be replaced without disturbing the lateral link bushing?</div> <div class="qf-faq-a">In principle yes — the cam bolt passes through the bushing's inner sleeve but does not require bushing removal. <strong>In practice however</strong>: cam bolt corrosion seizure typically involves the bolt being corrosion-bonded to the bushing inner sleeve. Forcing rotation can tear the bushing rubber-to-sleeve bond, damage the bushing housing, or crack the lateral link arm at the bushing eye. Either outcome requires lateral link / bushing replacement in addition to the cam bolt. <strong>Inspect bushing condition at cam bolt replacement</strong>: if bushing shows visible cracking, separation, or compression set, replace bushing simultaneously with cam bolt — this is the most efficient timing.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Should LH and RH cam bolts always be replaced as a pair?</div> <div class="qf-faq-a"><strong>Yes — mandatory.</strong> Both rear cam bolts have experienced identical corrosion environment, thermal cycling, and preload duration. If one side has failed or is showing corrosion symptoms, the opposite side is at the same wear stage and will fail within a similar interval. Replacing both during the same alignment service visit: (1) ensures consistent suspension behaviour across both sides; (2) avoids a repeat alignment visit for the opposite side; (3) eliminates the asymmetric wear that would result from mismatched bolt service intervals.

Pair replacement avoids repeat alignment service visit.</td> </tr> <tr> <td>Lateral Link Outer Bushing</td> <td>Subaru lateral link bushing, application-specific (e.g. 20254AE02A for Crosstrek/Forester)</td> <td>Cam bolt corrosion seizure typically involves bushing inner sleeve bonding; forcing extraction often damages bushing. Inspect bushing condition at cam bolt replacement; if visible cracking, separation, or compression set, replace bushing simultaneously — most efficient timing.</td> </tr> <tr> <td>Cam Plate / Eccentric Washer</td> <td>Subaru cam plate (application-specific reference)</td> <td>The cam plate engages with the eccentric profile of the cam bolt head. Worn / corroded cam plate produces inconsistent adjustment behaviour and compromised joint preload. Inspect cam plate at bolt replacement; replace if visible wear groove from previous cam bolt operation.</td> </tr> <tr> <td>Rear Lateral Link Assembly</td> <td>Subaru rear lateral link, application-specific (varies by model and year)</td> <td><strong>If cam bolt fracture has damaged the lateral link bushing housing or bushing eye</strong>, complete lateral link assembly replacement is required. Repair attempts on damaged lateral link bushing housing are typically unreliable; complete arm replacement is the correct approach.</td> </tr> <tr> <td>4-Wheel Alignment Service</td> <td>Workshop alignment service appointment</td> <td><strong>Mandatory.</strong> Cam bolt replacement disturbs rear wheel alignment regardless of careful installation. Full 4-wheel alignment service is required to verify rear camber and toe are within Subaru OEM specification, re-adjust using the new cam bolt's adjustment range, and prevent abnormal rear tyre wear from uncorrected alignment offset. Without alignment service, replacing the cam bolt does not complete the repair.</td> </tr> </tbody> </table> </div> </div> </div> </div> <script> function qfToggle(id){ document.getElementById('qf-body-'+id).classList.toggle('open'); document.getElementById('qf-chevron-'+id).classList.toggle('open'); } </script>
