HYUNDAI/KIA 55275M0000 ARM BUSHING
Product Specifications
| HYUNDAI/KIA | 55275M0000 |
The ARM BUSHING is a rubber-to-metal bonded sleeve pressed into the eye of a suspension control arm, subframe bracket, or trailing arm pivot point. It provides a compliant, maintenance-free pivot joint that absorbs road-induced loads in multiple axes while allowing controlled rotational and axial deflection within defined limits. The rubber element is vulcanised between an inner metal sleeve — through which the pivot bolt passes — and an outer metal shell that is pressed into the arm eye, creating a joint that requires no lubrication and isolates vibration and noise from the body structure. Polyurethane bushings are available as a higher-stiffness alternative for performance and heavy-duty applications where precise geometry control takes priority over ride comfort.
This unit — HYUNDAI/KIA 55275M0000 — is manufactured to OEM-equivalent specifications: outer shell diameter and length, inner sleeve bore, rubber compound durometer, and void geometry are matched to the original part to replicate the OEM deflection and isolation characteristics. Available wholesale from 3.53 USD, MOQ 1 pcs, production lead time 60-120 days.
Arm bushings degrade through rubber oxidation, oil contamination from adjacent leaks, and cumulative fatigue from billions of load cycles over the vehicle's service life. Degradation is gradual and often goes unnoticed until alignment cannot be corrected to specification or handling becomes noticeably vague. When one bushing in an arm is found to be split or collapsed, replace all bushings in that arm simultaneously — they have experienced identical service conditions.
- Remove the control arm from the vehicle before pressing bushings. Attempting to press bushings in situ without proper support risks damaging the arm eye or misaligning the new bushing. Support the arm on a bench press or hydraulic press with the correct sized adapters.
- Press out the old bushing using a hydraulic press with a stepped mandrel that contacts the outer shell only — never drive the bushing out with a hammer and drift, as this distorts the arm eye bore and prevents the new bushing from seating correctly.
- Clean and inspect the arm eye bore after extraction. The bore must be smooth, round, and free of burrs or raised metal from the old bushing shell. Dress any high spots with a fine file and verify the bore diameter matches the new bushing outer shell within 0.1 mm for an interference fit.
- Apply a thin film of rubber lubricant or soapy water to the outer shell of the new bushing before pressing — never use petroleum-based lubricants as these degrade rubber. Align the bushing voids with the correct orientation relative to the arm axis as marked on the OEM part or service manual.
- Press the new bushing in squarely using a suitable stepped adapter that contacts the outer shell evenly around its circumference. The bushing is correctly seated when the outer shell is flush with or recessed to the specified depth in the arm eye — verify with a straight edge.
- Install the new ARM BUSHING (HYUNDAI/KIA 55275M0000) back onto the vehicle, start all pivot bolts by hand, and torque all suspension fasteners with the vehicle at ride height on a flat surface — never torque rubber bushings at full droop. Have wheel alignment checked and adjusted after installation.
