• Position: Rear lower control arm / lateral link - connects rear axle assembly to chassis/subframe, controlling wheel lateral and longitudinal position under dynamic loading.

• Functions: Maintains correct wheel alignment geometry under load, ensures stable rear-end handling, helps manage camber and toe changes, absorbs suspension loads, supports consistent tyre contact and handling predictability.

Over time, the rubber bushings and ball-joint interfaces of control arms degrade due to stress, heat and fatigue. This can result in excessive play, clunks over bumps, vague handling, uneven tyre wear, and difficulty maintaining alignment. Fitting a new, correctly spec’d OE Match arm restores precise suspension geometry, improves handling confidence, reduces unwanted movement, and prolongs the life of tyres and associated suspension components.
