Thread: High KMS - Transfer case...

Graeme, I would be very interested to hear how your 8hp output splines look. I’ve only read about this issue applying to 6hp transmissions.

Yep but what JC is saying is that the gearbox will need rebuilding anyways around the kms the splines wear out at 250k-300k kms.

The TC part number was superseded for all MY11 L322 and for some or all MY11 D4, with Microcat showing a starting MY11 VIN BA567766 which could be the start of MY11 D4s and the part number has been superseded several more times since. I wonder what improvements have been incorporated.

When my transmission failed to proceed at ~130,000 KM the transfer case was also replaced as the coupling was severely worn. 2007 D3. It didn't look like it had ever had any lube on it from new.

ok,

so G box re build - 7.5 k
TC another 1k?

I will get it pulled with G box out and see how we go - suspect the re build coming.

bit depressing But then again 325,000k.

A couple of pictures of my output spline and transfer case from 2011. The vehicle had ~130,0000KM on it and was a March 2008 delivery. I'm dubious that there was ever any lube in there.

Having discussed the task with the local mechanic who R&R'd the D4 gbox, I now only have to decide whether its worth paying $50 for the LR grease and O-ring kit or just use moly grease without fitting a new o-ring.

you have to pull the tc out right? or can do with out total extraction to get lube in?
$50 for an o ring - i would book that (but assume pulling out)?

Yes, unbolt the TC from the gbox and at least move it back far enough to clean the splines.
Effectively $50 to have a new O-ring on hand if its needed.
