If the car has got to 84K then it would have failed by now...

If they do the work and you get vibration they will not fix the vibration for free - how will you prove it wasnt there beforehand etc?

If they do the work and the diff starts to leak oil because they damaged the seal how will you prove they damaged it?

If you walk back to your car to find the mechanic holding down the adjuster on the steering column so it breaks the motor - how do not smack them in the face when they say that will cost you £800 to fix!?

I'm don't agree with this. The issue with the propshaft is that it is sometimes not very accurately aligned when assembled in the factory. On a badly aligned shaft the splines begin to wear at the diff end and eventually they give up altogether. The rate of wear will be dependent on the amount of misalignment. So if there is only very slight misalignment then it could still go pop but it might not do so until 85k. Similarly, if someone has their propshaft or diff taken out for other reasons it could be put back together less accurately and could similarly go pop after a period.

In my opinion, if there is a recall it has been done for a good reason and it needs to be carried out.

I've never heard of a diff blowing at that mileage - of course that doesn't mean to say one never has... but to do 84,000 miles with a misaligned diff would be a miracle. The ones that left the factory weren't "massively" out in the first place and obviously as the splines have to line up there are only X number of ways to locate the shaft.
I would speculate that the misaligned ones were only 1 or 2 splines out as any more and it would have been glaringly obvious.

Personally though, I would rather go without the raft of issues experienced after this recall has been carried out.


On the topic of recalls, in the states they have recalled the L322 over the front cat's falling apart. We have the same parts, but no recall. They also have a steering column recall, we have no such recall.

Recalls are all about what LR think they can and cant get away with.

I'm not sure what you mean by "1 or 2 splines out". As I understand it the issue is one of alignment i.e. positioning of the centre differential relative to the front one, thereby causing the splines to engage at a slight angle. There is a CV joint on the rear of the propshaft near the centre diff, but not on the front. The modification inserts a CV at the front end of the propshaft thus allowing for some misalignment.

By extension of your second theory with regard to recalls, LR obviously don't think they can get away without doing this one. I reckon that tells us something...

Correct, but if you ensure there is no misalignment in the first place then you don't need the flexible coupling.

When this system is used in BMW's there is no need for this, the problem stems from Land Rovers "Slap Dash" build approach. It's not fair of me to tar every LR build line employee with the same brush, after all there are thousands of RR's out there who's Diff's have not failed and who are on their second owner (so know nothing about the recall)

Land Rover have acknowledged that the bulk of failures were at 30-40K then in another 30-40K after replacement (before the flexible flange)

I don't really see it as a build quality issue. I see it as a design fault. As you know they changed the design for the later cars.

It had a different engine & gearbox...

The LR bulletin says that the problem occurs from being misaligned on the production line. Simples.

On the BMW X5 that uses the same drivetrain this doesn't happen. Simples.

That doesn't matter - the gearbox output shaft connects to the transfer box which transmits power to the front and rear propshafts via the centre differential. The only connection between the engine and the front differential is that they are bolted together at the sump. So the design of the front diff/prop wouldn't need to change if the engine and box was changed other than to address the mounting points.

I still think the apparent "risk" of having some other knock on problem is worthwhile. Perhaps by now they've done so many of them that there's less chance of a cock-up? !

"OVERSTEER" ------is when you hit the fence with the rear of the car.
"HORSEPOWER" ----is how fast you hit the fence.
"TORQUE" -----------is how far you take the fence with you.

Both of my range rovers had the diff recall done by strastone Newcastle, they collected the cars, valeted them, and returned them the next day.
Works were carried out within a few Days of asking......they must have needed the work!!!!!!
