RTAB Wear

Rear Trailing Arm Bushing (RTAB) Wear

RTABs are one of the most common rear suspension wear items. When worn, they compromise rear-end stability.

Symptoms

• Clunking from rear over bumps
• Rear end feels loose or wanders
• Excessive rear tire wear
• Failed rear alignment (can’t set toe)
• Visible bushing deformation

Diagnosis

1. Raise rear of vehicle
2. Visually inspect bushings for cracking or deformation
3. Try to move trailing arm by hand — any movement indicates wear
4. Check alignment specs — worn RTABs cause toe changes

Repair

See the RTAB Replacement page in the Suspension section.
