Ashcroft ATB/Torsen Diff Front, Centre & Rear Install

**Bobby D** · 3rd December 2016, 12:51 PM

Wow, a very happy Christmas to yourself indeed!

This has made me very excited, my LT230 ATB and R380 with HD rear support bearing should be shipped out from the UK on Monday.

Just managed to squeeze in a booking with my local Landy mechanic to get the new gearbox and a new clutch/DMF swapped over before Christmas... also getting a Td5Inside Hybrid Turbo put in, all a big whack to the back pocket. I think the LT230 ATB will have to wait until Feb or so.

Good luck with the job.

The extra spline ones foul the factory alloys unfortunately.

*For the diffs any reputable diff or speed shop would be a good bet for setting the diffs
You will save money if you take the front and rear diffs and the ATB/ bearings and seals into the diff/speed shop and say here fit these!

Thanks Steve.
Yeah I figured a diff specialist would be the go for the front/rears. We've got a few driveline guys around here.
The pinion shouldn't have to come out should it? Or only if the thing has been that badly set up from the factory.

A salisbury rear with detroit locker will fix any upcoming issues ( and there will be with that rear diff) for ever...��

Yeah I know. I wont go down that route though.
Despite the known P38 type diff issues, I'm sure if its properly set up and driven by myself, then I won't have problems.
Pegging might be an option and I wish Ashcroft made a HD R&P for the P38 like they do for the rover.

I was actually on the verge of just ordering two completely assembled, pegged diffs ready to bolt straight in. $$$

Who is your Landy mechanic Bobby?

A new joint that has opened up in Fyshwick called The Series Workshop. Run by a fantastic gentleman named Johnnie, he knows his stuff. Things have been working out for him, every time I drop in there seems to be more Deefers and discos there

There it is..... Justin-Salisbury-C
He is correct though, but we have covered why most Defenders dont need it

The LT230 transfer case in the Defender TDCi (puma) has changed from what was used in the earlier model Defender, Discovery 2 except the detent position for the range selection, the extra ribbing on the case, what has changed though is the method of how they were doing the preload on the centre diff. The two selective shims on each end of the diff are a one size fits all, instead of using the correct thickness to obtain a good pre-load. On every Defender TDCi I've checked the preload, they have all been very average to poor.

Add to that.... A LOT of new Defender TDCi (puma) owners are new to owning a Land Rover, let alone a Defender, and have not been shown (or read) the need to engage the centre diff lock for anything more than gravel, assuming in part that the traction control would do whats required, this in turn causes excessive wear on the copper shims on the side gears of the centre diff.

Re HTE rear axles / drive flange, they fit for the standard Defender alloy wheels, BUT the centre plastic cap wont clip on. Other alloy wheels such as what was fitted to the SVX model, also fit, but again the plastic cap wont clip on.
