I seem to have acquired a leak where the driveshaft meets up with the rear diff. Anyone else noticed this?

No problems here. But my warranty runs out in 3 days so it will prolly happen in 4...

I had the same problem. It'sa badseal. Mine was fixed under warranty, but it can be that hard. My truck was only in the shop for about 20 minutes when they said it was done and it hasn't leaked since.

My 06QC had a small leak at the same location(Pinion Seal). Took minein just before the3/36 ran out and it was covered under warranty. I saw the dealerinvoicesheet andI believe thatit was ~$185 for parts & labor. DIYers, as you might expect,replacing the sealrequires aspecial holder and installer and an accuratestarting torque of 210 ft lbs. Servicemanual states to removebrakes(assumingdrums)in order to measure and obtain the proper pinion rotating torque before and after the seal installation.

Data below taken from section 3 of our Service manual:
CAUTION: Do not exceed the minimum tightening torque when installing the companion flange retaining nut at this point. Failure to follow these instructions can damage the collapsible spacer or bearings.

Increase in5ft lb incrementsuntil proper rotating torque is achieved.

NOTE: The seal replacement is unacceptable if the final pinion nut torque is less than 285 NÂ·m (210 ft. lbs.).

Had mine done some time ago. Just a very small moist spot the dealer notice when I was getting a free check-up on it.

So they just did the warranty thing and replaced the pinion seal.

I am lucky to have a dealer who goes out of their way to make sure things are in top shape, and also warranty any work.

Remove Drive shaft, mark Differential yoke retaining nut and shaft with a punch, count the # of threads before removal of nut, remove nut, remove yoke andseal, replace seal, install yoke and nut the proper amount of threads you counted going 1/8 inch past your punch marks, reassemble drive shaft check fluid done.
