Thread: Persistant transfer case leak on disco2

Any idea of the possible problem? They removed the case and replaced the seals each time, and I guess inspected surfaces of shafts for wear. Its a 2000 model disco two, about 170k ...

Maybe they are damaging the seal lips every time they reassemble. Just because they are a LR stealership doesn't mean they will always get it correct.

Agree - unless the t-case is lined up perfectly it is easy to damage while reassembling.

The method many people use is to slide the seal over the mainshaft, then line up the t-case, then only fit the seal just before all is tightened down.

But someone posted a very good method on here - using some really long bolts with the heads cut off to line up the t-case so it slides straight on without damaging the seal.

Maybe the same section (read Muckanic) is doing the job each time using his same method?

Being a cynic, but are you 100% sure they actually tackled it, or just handed it back saying they did?

I'd be a bit sussed on whether they've even done anything. I know that I've had my TC out a few times (also trying to fix leaks) I've been a tad rough putting it back in and re-used the seal for two installs with definately no leak from the input seal.

Sounds lioke what the Stealership did to me when I bought a used Dsico. I took it back under warranty with an oil leak from the head gasket. They fixed it by giving me a loaner for the day, steam cleaned it and told me it was only oil they spilt during service. Yeah I got tossed!!!!!

Ive posted that a couple of times but for putting the bell housing up to the engine. IT will work for the Tcase but you have to pick the right holes.

I prefer to put tcases on with the gear box removed and with the box standing on its nose then lowering the tcase down onto the back of the box from a vertical position.

on the note that 4bee sugested blackwood fords got really shippy when I pointed out that theres no way they did some of the things they claimd as the paint pen marks I had put on fill bolts and drain bolts hadnt shifted nor had the lip of it on the washer cracked in any way. They got even poopier when i pointed out that the wheel rotation hadnt been done cause the black light that I just waived over the rims still had the positions marked on them where I left them (IE LF on the left front tyre). Took the service manager to come out to believe that one. when I wanted to know how they did the brake pad check without removing the wheels and started making noises about I paid for it It will be done now or I will get a full refund and a free extention of my warrenty on the basis of poor dealer servicing he sort of went a very funny colour and headed back to the service department....

Paint pen the bolts and the joint between the gear box and the tcase, see what happens.

Dave, they only got shippy & poopier because it appeared to them that you didn't trust them to do the work you were paying for.
