My Diff failing as well

[pbhawkin]

Well, I just had my TDV MY07SE (so NOT an early model) WITH a ediff (never used/activated) in for it's 4 year service and was told it is failing and needs replacement. The dealer had allready contacted Alliance (the extended warranty people) who have 'pre-approved' it and so the dealer had ordered it!!
My extended warrenty expires in April 2012.
The car has 70,200Km on it and has had no real 4wd'ing and little in the way of towing anything other than an occassional box trailer with some wood once or twice.
It mostly does the communte to work (6.5Km) and the occassional long trip on highways with the family.

I certainly wouldn't say that this is NORMAL wear. AND that I am lucky I have the extended warranty! 4 years CAN NOT be normal life expectancy surely??

Basically means that any future LR products will have the extended warranty taken at purchase and the car got rid of before it expires. Why take the risk, of what is building up to be a rather long list of common issues occurring (hand brake, EGR, Diff, excessive tyre wear, etc) even when the car is within the 3 year manufacturers warranty?

I have posted this on Disco3.uk forum too.

comments?

I had front and rear at 33 months and 37000km last Aug. Highway and
no loads . The fronts are renowned rubbish , the rears far less so.

what is the cost for replacement of a front & rear diff?
Independant vs dealer

Nooooo - I have a 09 RRSTDV8 with 88000 on the clock and have had no problems - I feel a bit nervous

[dangermousehouse]

What are the symptoms of this?

Did you suspect there was a problem, or has the dealer bought it to your attention.

Is this limited to the e diff type?

A diff failing on a 4 year old vehicle! holy smokes, maybe they applied the same philosophy as ZF did towards the 'gearbox filled for life'

Best change your transmission oil........Do a search.

As Neil note the front diff is a reasonably well know problem, not heard of many with the rear diff having an issue.

There is plenty of discussion about ensuring the diff oils are changed a much more regular intervals than suggested by LR. I had my last service (45K) done by a Sydney independent and he advised me he was going to change the diff oil and did that together with the normal service for less that the dealer had quoted me.

Still failing diffs are a concern particularly in a vehicle that sounds like it has done very little if any "hard work".

Extended warranty is obviously a good idea.

My independant suggests changing all oils and filters after the first three thousand k's. It makes sense to me - however fine modern machining has become, there is still likely to be some swarf from the running in process.

He also recommends transmission oil changes at 40,000 k's. He has stocks of the relatively inexpensive Penrite ATF that was available before ZF stopped supplying their special additive to Penrite.

I arranged to have my 3.0 engine oil changed at 9K but the correct oil was unavailable from LR so had to wait until 22K, although possibly the "correct" oil was for DPF-fitted vehicles, which mine is not. I had both diff oils changed at 9K and again at 45K to check for metal contamination and will have all oils changed shortly before the end of warranty which will be around 90K.

Hello All,
I had my D3 transmission drained, flushed and refilled with new Penrite ATF Synthetic oil by a Sydney Indy in May, 2010. This was at 110500 Km and it was a great improvement until 3 months and 7000 Km later when I started having problems and eventually required a new gearbox.
Of course it may have not been the Penrite oil which was the cause but if I go down this road again I will definately use ZF ATF. Also I have since been told by a Ford workshop foreman that when he was on ZF training course the German instructor stressed this point. I know that OEM people always say this but he convinced the mechanic.

Thanks for the warning, swampy1. My indy was told that Penrite was buying the ZF additive, but that after a while ZF refused to supply them.

But who knows? Is the problem the lack of an additive, or the presence of something in other oils that maybe dissolves some very special material in the ZF box?

Not worth the risk - I will stick with the genuine ZF ATF.

Cheers,

My 2008 D3 gone in for 60K service and 3yr wty expires in 2 weeks. Therefore asked they perform wty check. Within 2 hours was rung to say - whine in fron diff so will replace under wty, excessive movement in fron suspension so replacing ball joints and other components etc. As far as i was concerned having just also replaced 4 Cooper LTZs and got a great deal from Cooper as they had not made it to the 50K warranty mark, the D3 was running and handling really well. I had agreed to the extra fuel injector service over and above the standard minor service charge and had just stated I thought that there might be more frequency and more of a clunk when accelerating away afer foot off. Wow really happy they are so on to it and doing all this no questions asked but sure does make you wonder, how you could expect to run without taking up the extended wty! May have to think more seriously about back to basics defender options as in an earlier post in general chat re changing from D3 to older defender. Still the extended warranty price does not seem too outrageous and at least the dealer seems to really be doing the right thing and did so with the previous Disco as well. I do like to get them dirty and another trip west is on the cards. I will say that the current D3 has been absolutely flawless and I would not have suspected any of the above needed doing.

.... I started having problems and eventually required a new gearbox..
What was damaged ?

[rob4play]

What was damaged ?
Don't know yet just had the call to state doing due to whine in diff and movement in front suspension. Ordering the parts in, apparantly all in stock so should have back Monday or Tuesday and get a better breakdown then.

.... My indy was told that Penrite was buying the ZF additive, but that after a while ZF refused to supply them.
But who knows? .
.. When Penrite first started claiming their oil was for
ZFHP26 box , a few of us asked for a specific details and a
guarantee. Their HQ wouldn't supply such info , and shortly
after D3's began failing , they withdrew the claim of compatibility. :mad:
Reckon they just thought they'd have a bit more market ?
I really would like to know what's SO special about it's content .........
or rather , why the box is such crap without it.

[Tusker]

Just a thought..

Anyone know what oil Ford are running in the Territory 6 speeds?
