Loud "bang" from the back?

[BUNNY15]

Devilsfan I remember your lift because I was a huge fan and thought I would be using the same system and set-up. In the end though, I decided against it due to towing concerns, but let me ask you, have you ever noticed any fluid dripping from where the yoke meets the transfer case? Even minor drips?

The reason I ask is because I ended up going with the Fabtech 6" and 40x15.50 but experienced this problem with the pinion angle being too aggressive causing more slippage than expected, soon to fail if not corrected. To make a long story short, I did not notice any loud noise with the problem, but I agree with HUMTECH. You may want to look at that for sure because mine was driving just fine too, and I just happen to notice the SMALL leak by chance one night in the driveway.

I have noticed that unless you just crack the case, then the problem can lie within the early cases and you not even know it until it's too late. There was no sure way for the tech to tell me why it failed or when, but that I had sheared some of the original casting where the later models have a rubber bushing. The early cases did not have that. Keep us posted. I know I'd be interested in the root of the problem. Good luck!

p.s. I ended up having to replace the entire back casing of the tcase and lengthen the stock driveshaft about 1.5". The shop that did the lift (biggest national company around, wink wink) said they had not encountered this kind of problem on the H2 using a 6 and 40x15.50s in the past.
