Rear Right Suspension Control Arm Assembly

Why you need it

This rear right control arm keeps the wheel in the correct position, holds camber and toe, and stabilizes the SUV under load. Fresh bushings and joint reduce vibration, stop uneven tire wear, and restore quiet, solid handling. It’s a critical link for safe braking, straight tracking, and comfort on rough roads.

How it works

The arm connects the rear knuckle to the subframe. Rubber bushings and a precision ball joint let the wheel move up and down while resisting side and fore‑aft forces. Under cornering and braking, the arm locks wheel geometry so the tire stays flat on the road . Correct geometry equals grip, stability, and long tire life.

What happens if it’s bad

Worn bushings or a bent arm cause clunks, rear steer, shudder at speed, and fast tire wear. Alignment won’t hold, ABS/traction can trigger, and braking distance grows. In severe cases, joint failure risks loss of control ⚠️.

Symptoms to watch

• Clunk over bumps from rear right
• Feathered or cupped rear tire
• Wandering or pull, poor straight-line feel
• Torn boot, cracked bushing, rusted arm
• Alignment out of spec after short time

Pro tip: replace hardware, torque at ride height, then perform 4‑wheel alignment ✅.
