Detailed Description

Delphi TD4957W is a rear suspension stabilizer bar bushing kit engineered for 1997-2001 Infiniti Q45 applications with the specified suspension package exclusions.

What It Helps Address

• Rear sway bar movement caused by worn bushings
• Clunking or rattling from the rear suspension area
• Excess play at the stabilizer bar mounting point
• Reduced suspension response from deteriorated rubber bushings
• Fitment issues when replacing an aging OE rear bushing

Installation Notes and Tips

Confirm rear application, suspension package, and bushing dimensions before installation. Inspect the stabilizer bar and surrounding brackets for wear, corrosion, or deformation before installing the new bushings. Because mounting hardware is not included, reuse or source the required hardware separately if needed. For best results, compare the original bushing shape and measurements to TD4957W before service.

Quality Assurance

Delphi subjects its OE-based suspension and steering components to extreme temperature and salt-spray testing, along with dimensional and material analysis, to support consistent aftermarket replacement quality. TD4957W is built as a standard replacement part for the listed Infiniti Q45 rear applications.
