I've been leacking fluid from my tailshaft housing boot. I don't know why it started leaking after I replaced the u joints in my d-shaft. WHat do I need to replace to fix leak and how hard is it? Should I change My t-case oil as well? If so What is the process and how much fluid?

TIA

3. Use a suitable chisel or pry tool to remove the rear
extension housing dust boot (2).
4. Use a suitable chisel or pry tool to remove the rear
extension housing seal.

inspect for defects.
2. Install the extension housing dust boot and seal
assembly with Installer 9037 (3) and Handle

allow the plugs to be accessed for torquing during

So it seems as thow I damaged the seal behind the dust boot? Where Can I get this Seal. Thanx for that info

 

Not sure if its a dealer only item, check the parts stores I guess. If not, then I think this might be the part.

I have had my 06 Dodge 3500 in the shop many times for a leak, and had a boot replaced and was told this was the problem. ONLY to find out now that they tell me it's the Transmission Tailshaft Housing Leaking and cost to replace is $737 (parts, labor, and tax). I have 63K miles on my 06 and have had it in the shop many times for leaking.

What other options do I have for fixing this problem?

 

Va.Diesel Please fill out your Signature so everyone knows what your truck is equipped with. Have you crawled under to see exactly where its leaking from? Could still be the seal, maybe your slip joint has a burr or nick, and damages the seal when the DS is re-installed.
