Thread: 2010 2.4l 110 Puma Deefa:Front Diff Gone Bang in the Night

The Ashcroft ATB should fix that problem. I've used truetrac's in the past for that same reason. The only issue I found was getting your tyre pressures right to equalise the tyre diameters - if there is a slight difference in tyre diameter, left to right, the vehicle will want to wander to the side with the smaller tyre.

It is usually not so much a strength issue with the two pinion centre, but more that the hole for the cross pin wears and the cross pin works it's way out until it jambs, or breaks. Yes they suck and Land Rover have hardly ever built a strong drive line in all of their 65 years.

I have read that the life expectancy of a Rover diff with traction control is in minutes not hours.
I went the ATB for this very reason

Yes I read that bit about traction control last night as well.... Is it just a matter of bolting on the new Ashcroft atb? Is it a specialist job?

That is the Ashcroft sales pitch. If they were that delicate in practice the diffs would be a service item on D2's.

Paul this is nothing to do with Ashcrofts and they never claimed this in any way.
The information I quoted is what I read on a forum, I don't think you can doubt the weakness of the 2 Pinion Rover Diff.
The Leyland Brothers had the same problem in the wheels across the wilderness adventure in 1966.
I dont think 29dinosaur will argue either as he has the photos to prove it.

That said when I removed mine it didnt seem too bad and it had done 170 K with TC

If you just get the ATB, you'll need to set the crown and pinion lash - can be done at home but its not an 'easy' job.


If you go a full replacement third member, it's just a basic replacement of a non-broken version of the bit(s) you have already removed.


I'll try and put up a pic of mine tonight. Out of interest - is there a gasket under the dif centre, or is it just silastic?

You're right not Ashcroft. But it is a US based vendor of the ATB diffs who claims 30 minutes to an hour life out of the rover diffs with traction control. I take that kind of opinion with a large serving of salt.

I've seen video of the Moab(?) rock crawling those Utah guys get up to, and I wouldn't be surprised if you could kill a diff in an hour if you subjected it to an hour of continuous battering in those circumstances.

To me that is pretty extreme usage, and I find it a bit difficult to use that as a benchmark for life expectancy if the diff.

Just the silastic goo....
