I own a 02 ram with the 4.7 and while at the muffler shop getting duals they noticed some tranny fluid biult up and said i had a transmission seal leak. its right where the drive shaft and i believe transfer case meet. Its barely leaking and not causing me a great concern right now but i was wondering how hard it would be? i am pretty mechanically inclined and can do quite abit but to replace the seal would i need to drop the tansfer or tranny or could i just slide under drop the shaft and then pop a new one in? any help is appreciated.

 

If the leak is where the output is on the t-case, then you could just drop the driveshaft and replace the seals. It is a fairly easy job (experience w/other vehicles, not the ram). Be careful when you pull your old seals not to scratch up the inside of the snout on the t-case. Also, a bit of gear lube will pour out so watch out. When putting in the new seals set them in perfectly square to the snout. Put a little gear old on the lips of the seals then plug your driveshaft back in. Done. Hope this helps.

If someone has better experience, then please correct me. I would like to know too in case it happens to me. Thanks.

 

Front and rear main seals can be a PITA to replace. Not because it is technically difficult, it is just time consuming and you only have limited space. Throw in the fact that you probably don't have a lift makes it that much of a PITA.

Personally, if it is super small and you keep an eye on the fluid level, I'd let it go for now with the knowledge that it will need to be replaced in the near future.

 

Yeah, thats a better solution....

 

Oops. I re-read the post and see that you are referring to the drive shaft seals. See what DeWalt said regarding seal replacement. But as I said earlier...
