Delphi TC4662 Lateral Arm - Rear Lower Rearward

OE-Style Rear Lower Rearward Lateral Arm

Delphi TC4662 is a rear lower rearward lateral arm built for select Audi suspension applications. It uses a forged aluminum construction with rubber bushings to support rear suspension geometry and consistent alignment on the road.

Compatible With Audi A6 allroad, A6 Quattro, A7 Sportback, e-tron Quattro, Q5, Q7, Q8, RS6 Avant, RS7 Sportback, S6, S7 Sportback, SQ5, SQ7, and SQ8 rear lower rearward positions across 2017-2023 model years.

• Forged aluminum construction for strength and reduced unsprung weight
• Rubber bushings included for OE-style isolation and ride control
• Black matte, uncoated finish
• Bent arm shape for the specified rear suspension geometry
• Standard replacement grade for direct service use
• Non-adjustable, non-greaseable design

Detailed Product Overview

The Delphi TC4662 lateral arm is engineered for the rear lower rearward suspension position and is built to match OE-style dimensions and material characteristics. Delphi applies dimensional and material analysis to help ensure proper part-to-vehicle compatibility, and each component is tested for temperature extremes and salt-spray exposure to support durability in demanding conditions. This part cross-references Mevotech Supreme CMS701206 for the same application.

Use Delphi TC4662 when servicing rear suspension wear on Audi A6 Quattro, Q5, Q7, and related models listed below. The part number TC4662 is also a useful reference when verifying replacement options for the rear lower rearward location.

Common Issues This Part Can Address

• Rear suspension looseness or clunking from worn bushings
• Uneven rear tire wear caused by suspension geometry changes
• Rear-end instability over bumps or during lane changes
• Alignment drift after bushing or arm wear
• Excess vibration transferred through deteriorated rubber bushings

Installation Notes and Tips

Install in the rear lower rearward position only on the listed Audi applications. Because mounting hardware is not included, reuse or source the correct fasteners separately as required by the vehicle. After installation, perform a professional wheel alignment to verify rear suspension settings and restore proper handling. Confirm bushing orientation and mounting hole dimensions before tightening to specification.

Quality Assurance

Delphi builds this suspension arm using OE-focused engineering practices and subjects parts to extreme temperature cycling and extended salt-spray testing. The TC4662 is designed as a standard replacement part for service work where OE-style fit, material selection, and durability matter.
