Vibration and Chattering Noise When Cornering

SYMPTOM

Chassis vibration and tire chatter noise when cornering.

PROBABLE CAUSE

The rear differential has an insufficient amount of limited slip differential (LSD) lubricant additive. An LSD additive or a gear lubricant with LSD additive was not used when the rear differential lubricant was changed.

DIAGNOSIS





To verify the vehicle is equipped with a limited slip differential, open the hood and check for the option code G80 on the ID plate as shown.

CORRECTIVE ACTION

Add the LSD lubricant additive listed under REQUIRED MATERIALS to the rear differential.

1. With the rear wheels supported and the chassis level, remove the rear differential filler plug.

NOTE:
If the rear wheels are not supported, differential lubricant will flow out of the filler hole when the plug is removed.





2. Using a suction gun or a syringe, remove approximately 4 ounces of lubricant from the rear differential.

3. Add one 4-ounce bottle of LSD lubricant additive to the rear differential, then reinstall the filler plug and tighten it securely.

4. Drive the vehicle in tight left-hand and right-hand circles, (approximately 10 times each) to distribute the LSD lubricant additive.
