Had a nice freebie winter check done by my local Jag dealership which was nice until they kindly informed me that I have a slight N/S rear diff leak

They said to monitor it for a little while, but just wonder if anyone has had their rear diff replaced and rough cost? May also wrap replacing the rear bushes at the same time, as I'm obviously going to have to sell a kidney to cover the cost.

Also with the age of the car, would you recommend replacing the sump at the same time?

Thanks.

 

There's a great thread in this forum by 'flyc2c' on putting a Quaif LSD in. Parts cost is around $1500.

 

I would have thought that the drive shaft oil seal could be replaced. You can on most diffs rather than change the whole diff

 

It can be. The entire diff is rebuildable/re-sealable. Any driveshaft/diff/manual trans shop can do the work. The remove and replace is the expensive part which my thread shows you how to do. Depends on the DIY level.

 

Wrong thread, sorry.

 

I’m not sure how old yours its but there is a batch of bad Jagdiffs around 2008/9 model years. Anyway, I had the same issue and initially hadthe drive shaft seal replaced which lasted only a month (120GBP) before leakingagain. I then had the whole diff replaced with a 2nd hand unit at ajag specialist for about 600GBP which has been fine for the last 2 years.


Sonot too horrific.

 

I believe there is some interchangeability with other Jaguar models as well.

Cambo would be a good resource for that.

If you have a high mileage vehicle and don't want to invest too much, I'm guessing you can pick up a low mileage used one on the cheap.

As Flyc2c points out, you don't need a Jag Dealer for this kind of work so either rebuild or replace can be done for less at a trans shop.

 

Just had mine changed as the L/H seal went which is how they all start to go.

I used a refurbished 2004 S-Type 3.0L auto rear diff and just changed the back plate as it has a different cooling vane. Both have the same ratio of 3.31, been spot on since replacement.
