I've got an 06 silverado and the right front axel shaft seal is leaking (40K miles). The dealership told me it would be $337 to replace. Before I had them do it I figured I'd look into it myself or have my mechanic do it.

I've got the Haynes repair manual and it looks pretty straight forward. The question I've got is, where exactly is the seal? There is fluid on the axle tube flange where it bolts to the CV joint, so I figure there is a bad o-ring or gasket there. However the Haynes manual has you pull the axle out and then replace the deflector, seal, and bearing of the differential. For some reason this doesn't seem right.

Has anyone ever replaced the axle seals before? Is the Haynes manual right?

I had the dealer inspect it today and they noticed the leak. I thought it was odd and told them not to fix it and I would discuss it in more detail when I picked the truck up. I asked him since its only 2 yrs old (bought March 06) if they could fix it under the warranty he said nope because I've got more than 36K miles. This is the dealer I bought it from and let's just say I'll never buy another car/truck there again. I don't have any confidence in them. The only reason I had them inspect my truck was because it was free.

I also had the arm rest break twice. Another dealer fixed it in January then shortly after it broke again, the retainer pin fell out. I tried to fix it myslef but I couldn't get the seat cover off so I said screw it I'll have the dealer do it so I don't have to struggle with it. Long story short the dealer today said they would have to order a new arm rest but then I told them how to fix and they were able to fix it. Of course they charged me so now I have to go to the other dealer to try and get the $50 credit.

Other things that have been wrong with my truck are:
-Knocking steering column
-Leaky intake gasket
-Clunking from the rear differential (had the original dealer look at it many times but they couldn't figure it out, they even changed the drive shaft but that did nothing. Other dealer said it was common and told me about the service bulliten)

I'm not too impressed with this truck.

At 40 k you should be able to get that seal goodwilled.Especially since it is only out by miles.

GMC Sonoma, thanks for the help. This is pretty much the exact same thing that I have in the Haynes manual. After reading this it definately sounds like the seal is at the differential and the fluid leaked down the axle tube and is leaking out the at the flange where it bolts to the CV joint boot.

Is it possible to remove the axle, bearing, and seal with out the special tools? ALso I couldn't find the parts on the NAPA or AutoZone website, do you know if they carry those parts or if I will have to get them from the dealer? Do I need to replace both the bearing and seal or just the seal?

I have an 06 Z71 I'm replacing the rear axel seals on my truck but I wanted to add that the steering coloum knocking was a recall in the GMC Sierra for 05 and whatever years the same column was used, as you may know they are damn near the same truck. I installed a body lift on my truck which included a steering extension to compensate for the 3 inches which just made the knocking worse. The fix I've heard is a new non-greasble shaft that GM has agreed to replace of trucks up to 100,000 miles, I havn't looked into it but I would suggest anyone who has the problem should get it to the dealer to check it out. It's a quick and easy install but the part and labour should be free.

Same Problem here. Leaky seal on Right front shaft on 2004 Silverado with 45900 miles. I asked dealer to check "Goodwill" adjustment. He said "No! No!" It has over 36K". I said I "only" asked you to check. He was aware of the problem but said "no help was available". Appointment is for Friday- said around $250.

This truck had a problem with the 4WD indicator lights when new which they finally repaired.

Surprise! I walked into dealership (Day-Centennial Chevrolet) in Uniontown,PA this morning to leave my truck for repairs to leaking front axle seal. Service manager said he talked to the boss and he and GM will give a Goodwill adjustment. He wants to change both sides and put in new bearings and fluid change. Said he had to order parts and will be in next week. First he said it'd cost me a $100 and then decided it would cost me $50. Said the dealership wanted to keep my business. I'm stunned! Thanks GMCSONOMA- it pays to ask. Hopefully the problem will be fixed. Guzda
