Thread: Bang goes the Puma diff

Sorry to hear.

If it is the Diff it's the first front diff failing on a Puma that I have heard of.

Noisey rears yes...but again not many catastrophic failures.

As Dave says above I'm sure that traction control and torque contribute but I would agree with Pete that a fundamental manufacturing defect is the likely culprit.

The cross pin has probably come out. For some reason LR insist on using these diffs in the front Defenders, (sold in Aust), instead of the stronger 4 pin unit, (which is a direct replacement).

If the car is out of warranty I'd suggest upgrading to the 4 pin, or an aftermarket center, (ARB, Detroit, Tru-track, etc).

Cheers,

Edit: Just saw your post about warranty, perhaps the dealer can be talked into fitting the 4 pin diff?? (Part number TBB000280)

Thanks everyone, I will certainly push for the 4 pin upgrade.

Here is a video of being pulled out:

As you can see, pretty **** weak.

WTF is a drive member? For $50 bucks, I'll have two though, think of some use for them....

I know rover diffs are weak, but I have a classic Rangie sitting here with 400000km on it, never done a diff and it has done its fair share of hard 4wding.

I have also seen smashed diffs on my friends Rangie's with 35in Simex and superchargers, and busted my supercharged Patrol on 36in swampers rear diff.

But standard size tires, easy 4wding low km car. Surely a manufacturing fault. Hopefully landrover come to the party and do it under warranty

Edit: Thanks for the 2 constructive posts above that were done whilst I was replying

Relax man. Your pride and joy might be temporarily busted but nothing that can't be fixed especially that you are under warranty.

A bit of lite-hearted feedback is surely not too much?

Hope you get it sorted mate.

Some interesting info on this thread. Especially the contact patch images Ashcrofts have put up.

Scary stuff!!!

Since some have had no issues and others have been through 3-4 diffs in one vehicle, it seems most likely a QC issue in machining or assembly.

If it is a front diff pin failed... its deffnetly not the first... i cant see why your worryed about warrenty... thats what its there for if its a tru not at fault problem... but theres no way they will swap it for a 4pin... and im sure a 4 pin rear wont fit in the front?
