The KNUCKLE STEERING is the primary structural hub carrier at the front axle that pivots about the upper and lower ball joints or the strut top mount and lower ball joint to provide the steering axis around which the wheel assembly turns, simultaneously serving as the rigid mounting platform for the wheel bearing hub assembly, brake caliper, ABS wheel speed sensor, and tie rod end. Cast from grey iron, nodular iron, or aluminium alloy depending on the vehicle's weight class and performance requirements, the knuckle is a highly loaded structural component that transmits all lateral, longitudinal, and vertical forces generated at the tyre contact patch into the suspension linkage during cornering, braking, and road surface impacts. Its geometry is precision-machined to define the kingpin inclination angle, steering axis offset, and wheel bearing bore concentricity that are fundamental inputs to the vehicle's steering geometry — caster, camber, and scrub radius are all determined by the knuckle's design dimensions and cannot be adjusted independently of the knuckle itself on most modern suspension designs.
This unit — PEUGEOT/CITROËN 364754 — is manufactured to OEM-equivalent specifications: overall casting geometry and machined bore dimensions, wheel bearing bore diameter and face runout tolerance, ball joint taper bore angle and thread size, tie rod end taper bore, brake caliper mounting face position and thread specification, and ABS sensor bore diameter are matched to the original part. Supplied as a direct bolt-in replacement for standard fitment. Available wholesale from 13.39 USD, MOQ 50 pcs, production lead time 26 days.
Steering knuckles are damaged primarily through impact events — kerb strikes, pothole impacts at speed, and collision damage — that bend or crack the casting, distorting the wheel bearing bore from round and shifting the ball joint taper bores out of their design angular relationship. A bent knuckle produces a characteristic steering pull, rapid inner tyre wear, and a camber angle that cannot be corrected by alignment adjustment alone because the knuckle geometry itself has changed. Always inspect the knuckle for dimensional integrity after any significant wheel impact before performing alignment — a knuckle with a distorted bearing bore or cracked casting cannot be safely returned to service regardless of how the alignment measures.
- Support the vehicle on chassis stands and remove the wheel before beginning disassembly — the knuckle carries the full weight of the wheel, hub, brake disc, and caliper; support the lower control arm with a workshop jack set just below its unloaded position before releasing the ball joint to prevent the arm from dropping suddenly and over-extending the driveshaft CV joint or brake hose beyond its travel limit.
- Release the tie rod end, lower ball joint, and strut-to-knuckle pinch bolts in sequence before attempting to withdraw the knuckle — use a ball joint separator tool rather than a hammer to release taper joints; striking the knuckle boss with a hammer to free a taper can crack the casting boss or damage the new knuckle's taper bore if the tool slips. Never use a pickle fork on a ball joint that is being retained for reuse.
- Press the wheel hub and bearing out of the knuckle before transferring to the new unit — the wheel bearing outer race is an interference fit in the knuckle bore; use a hydraulic press with the correct support plates to remove and install bearings without applying force through the rolling elements. Never use an impact hammer to drive a bearing into an aluminium knuckle as this cracks the bore and destroys both the new knuckle and the bearing.
- Measure the new knuckle bearing bore with a dial bore gauge before pressing in the new bearing — confirm the bore is within the OEM tolerance for interference fit; a bore that is oversized from a previous oversized bearing installation or manufacturing variance will not retain the new bearing outer race under cornering loads; an undersized bore will crack during pressing.
- Torque all taper joint nuts and strut pinch bolts to OEM specification with the suspension at ride height — ball joint and tie rod end nuts must be torqued with the joint in its normal loaded position to prevent the rubber boot from twisting and tearing; tighten all fasteners with the vehicle on its wheels at ride height or with the suspension jacked to the ride height position before final torquing.
- Install the new KNUCKLE STEERING (PEUGEOT/CITROËN 364754), torque all fasteners to specification, refit the wheel, lower the vehicle, and perform a four-wheel alignment immediately — knuckle replacement changes camber, caster, and toe simultaneously; never return a vehicle to the customer after knuckle replacement without a full alignment check and adjustment; confirm ABS sensor air gap is within specification and the sensor produces a clean signal on a scan tool before road testing.
