The following diagnosis might be helpful if the

vehicle exhibits the symptom(s) described in this

PI.

Condition/Concern:

Rear axle chatter or shudder on turns on Chevrolet

Corvette and Cadillac XLR.

Recommendation/Instructions:

Flush and fill the rear axle with synthetic axle

lubricant GM P/N 89021677 (Canadian P/N

89021678) and appropriate amount of the friction

modifier additive P/N 01052358 (in Canada

992694). See fluid amounts listed below.

Note 1: In some cases it has shown that a second

flush procedure on a second repair visit will correct

the chatter/shudder concern prior to replacement of

the clutch packs.

Note 2: To properly flush the rear differential

remove the left differential cover and get all of the

old fluid out off the differential, wipe out the

residue replace the cover o-ring and then reinstall

the cover and fill with the appropriate amount of

fluid and friction modifier additive.

If the complaint or the condition persists after the

flush and fill, replace the right and left rear axle

clutch packs following published service procedures.
