Reason Im asking is because my rear is 3.7 and the spare I have is 3.4. I cant see the tag on whats in mine and there is some severe continous clunking under load that's getting gradually worse that several workshops cant pin point. Thought Id buy another diff before the new engine is dropped in this weekend and the diff bushes get changed by a workshop either today or tomorrow. Any help would be appreciated.

People replacing parts to no avail and it almost always turns out to be transfer case. It is basically a separate unit with its own fluid ect so the box should be OK if its not currently giving you any dramas.

My bad on the diff specs I should of cleaned the sticker better all TTGs and FX6s are running 3.4s. Ok so who builds a tough transfer case? good for 500kw or their abouts???

The weak link is the awd box unfortunately.Lots of power plus heavy vehicle = broken sh*t Edited 28/05/15 04:50 AM by barnz Link to comment Share on other sites More sharing options...

Think Iv rang every gearbox/transmission place going. I bought a stock one today to get me through they aint cheap. Maybe 3D image it and give the file to a machine shop make it out of something better. Link to comment Share on other sites More sharing options...

I had to replace mine on my 08 F6X (90k km's) as the rear one was non existant and the bolt was just banging around freely. I've also just recently (96k km's) had the control arms replaced and the front radius arm bushes replaced as they were toast also. Surprisingly the rear diff bushes and all bushes except for the bump stops are still like new!Keep us informed though as I am doing some extra mods soon and will settle for whatever the standard turbo can put out but atm it is roughly at 270-280awkw (110mph at the drags).Cheers,Brett Link to comment Share on other sites More sharing options...

I can't however confirm that 100%. Just thinking we know the zf can be built to take 500kw, just wondering if a different transfer case can be made to work. I know r32 transfer cases are just about indestructible.... Unlike their gearboxes...Its a niche market so something off the shelf for the power your chasing is probably not going to happen.
