Rear Axle /Diff Seal

[als99]

Has GM come up with a resolution for the what seems to be frequent occurance of a fluid leak at the the diff and left rear axle? It seems I read several posts last year about this problem. My 99 has less than 12,000 miles and has started leaking badly.

there are newer seals now available that are supposed to take care of this.

When installing the rear axle side cover(s) a new o-ring and axle seal should be installed and a material such as Loctite® 518 should be applied to the outboard side of the o-ring. The sealant should be allowed to set prior to filling the axle with oil and driving.
