Downeast Johnny Posted December 2, 2016 Report Share Posted December 2, 2016 This is one of just a couple potential problems with this T-case. (Also look out for a leak at the output shaft seal. The seal seat can wear oblong and then a new seal won't cure a leak). Other than these problems, it is a strong unit. Guy's have run pretty high HP through them and they hold up well.

liftedssguy Posted December 2, 2016 Author Report Share Posted December 2, 2016 is there any early fixes to the rear seal issue? Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted December 2, 2016 Report Share Posted December 2, 2016 is there any early fixes to the rear seal issue? All I've ever heard about the seal leak problem is that it takes a new tail piece casting to repair. Quote Link to comment Share on other sites More sharing options...
Doughty08 Posted December 3, 2016 Report Share Posted December 3, 2016 Or it could be the output shaft bearing is in need of replacing, not a big job just don't buy from the dealership. If I recall correctly the bearing alone was 45 bucks. Quote Link to comment Share on other sites More sharing options...

Downeast Johnny Posted December 3, 2016 Report Share Posted December 3, 2016 (edited) The internet scares me sometimes. I was cruising another site and this came up as a pop up. (I hadn't searched for this part and so it had to be known that I had responded to this thread). Any-how this is what the "pop up" lead to. Looks like a good deal to me if you needed one. Made out of aluminum instead of magnesium. Hope they have a good method of isolating the two metals. https://www.amazon.com/gp/product/B00BI3JIPG/ref=ox_sc_sfl_title_1?ie=UTF8&psc=1&smid=AYUN1EXO5XQB3 Edited December 4, 2016 by Downeast Johnny (see edit history) Quote Link to comment Share on other sites More sharing options...
