Anyone know of known issues w/ the '02 2500HD 2WD rear axle seals? My Dad is
getting ready to have a third seal replaced in 91K miles before the warranty
expires. The first went around 50K miles, the second around 62K miles and
now the third! I had one go on my first '02 2500HD inside of 15K miles, but
have been fortunate on my current 2500HD 4WD at 41K miles w/ no issues with
'em thus far.

What is required in pulling the 2WD axle? Does the diff have to be opened
and a lock ring pulled or do you just remove the bolts from the plate and
pull it? This obviously for future knowledge once the warranty expires in a
few weeks.

Thanks,
Kevin

First thing I would check for is a plugged vent line on diff because
they generally have a very long life unless they are overheated realy
bad a lot for excessive torque loads. I have had seal not leak on 20
year old axles. Too heavy a lube in realy cold weather can shorten
their life too.

It is a full floater (whether it is a 10.5 or 11.5 depending on
engine) they still both just pull right out without even jacking
vehicle up.

Thanks for reply. I will suggest he ask them to look at the vent tube while
in the shop. I know he's going to ask them to go over it with a close
inspection, but you know how that can go. I will note though that we have
both had good results from the particular dealer it will be going to, so
hopefully it is done this time to last a long time.

Happy New Year,
Kevin
