Fits 2002 Dually Silverado Crew Cab

A 4" 10GA tube works well in pressing (pounding) these seals to the hub. It's a tight fit on axle shaft so don't forget to lube inside of this seal, and it's shaft (Teflon grease worked great). I suspect early failure, of these two piece seals, can be due to eventual loosening of hub bearings, which can happen, especially after installing new bearings(probable problem from factory as well) (the outer race of the outside bearing will eventually migrate in, to it's stop, which is a C clip), so best to check periodically for loose play (tire off ground). A spongy brake pedal is a good symptom of loose hub bearings.

Perfect fit

I have a 2005 2500HD. This was a tricky part to find and took a lot of research to make sure I was getting the right one. Even the local parts stores did not have the correct part listed. This stopped the leak at the axle. Easy to change. Just make sure you get ALL of the old seal off the axle. Sometimes the center part of the old seal stays attached to the truck. Mine was not hard to remove but the old seal did come apart and part of it was still on the truck.

2001 GMC Sierra 2500HD Duramax

Worked great on my 2001 GMC Sierra 2500HD Duramax’s rear axle. Both sides started to leak and this fixed it. You will need a special socket for the spindle nut and be sure to top off on gear oil. The rear bearings are oil bath and if you are low they will not be lubricated properly. Happy wrenching!

works!

When you go to remove the old one, MAKE SURE YOU REMOVE ALL THE OLD SEAL OFF THE AXLE TUBE. Took about hour and half to replace, but great fit.

Get the right seal for your GM 14 bolt axle to do the job only once.

Correct axle seal for the GM 14 bolt. Same seal what came on 2002 and newer trucks, this has the rubber inner seal that fits against your axle tube. This seal with also work on and upgrade your older 14 bolt so you no longer have the seal that rides on the housing. Only thing needed for the upgrade is this style seal, direct replacement!

Axle seal install

If you buy GM it always goes on perfectly. Can only guess how much they charge to do this job so I tackled it myself. Thank God for Utube video! Actually went pretty easy.

Why did I wait so long?

A couple of youtube videos showed how to replace these seals. Super easy with the right tools and a modicum of mechanical know-how.

This is the OEM seal!

Identical match for what was in my '05 GMC Sierra 2500HD. If you're a masochist go for a cheaper, non-oem seal. As much of a pain in the butt as replacing this seal is, I think is well worth a few extra $ for OEM. Not to mention that when your cheezo aftermarket seal fails again, you'll also need to replace the oil contaminated parking brake shoes again, and possibly disc brake pads, too.

Good factory replacement for AAM 11.5

Will fit any 01-10 AAM 11.5 rear axle. I primarily only trust OE replacements, this worked perfectly fine.

Upgrade

Its an upgrade from the one that came in the truck
