I wouldn't get a more modern Jag i.e. XF XE as I don't like them, too European looking especially the inside. I have been looking for a XK8 but again it's a parts problem as Jaguar cannot supply them any more and that means going down the second hand rout.
So there we have it and by the way the diff swap cost me five hundred smackaroonys (if that's the way you spell it) So I'm off to the pub now to drown my sorrows
Suggest a 5% by volume addition of a product called Extralube ZX1. This is a friction reducer which does not alter oil properties. Google www.team-zx1.com for further details. Call the company direct for a chat about this product. Stewart is the man to talk to. Mention my name and the JEC. You should be able to pick up a 250ml pot of the additive on Ebay for around £12. Its nearly double the price in Halfords!
I now have 300ml of ZX1 in my freshly EDT treated XJR. It certainly makes cold starts quieter on sub zero days and has gained me 1mpg on the motorway. Its an interesting product and I`m about to trial some in my supercharger sump due to increased lobe rotor gear chatter caused by having a stiffer drive coupling fitted. ZX1 is quite suitable for diffs even though high oil sheer forces are present.
Jag diffs of the period have always been a little suspect. Not particularly of the highest quality and with quality control problems at various times. Build cleanliness apparently caused many issues with cutting swarf and cutting fluid content sometimes being found in dismantled units. The issue also affected some X350 models as well. If you get a good one, that`s great. If not, well, what can we do except swap out for another unit. Watch for leaks on the near side drive shaft oil seal. That is the tell tale for a diff that is in trouble.
Drink more beer. It can`t do any harm.
I rang David Manners earlier and explained the above to find out how much a new shaft would be and he told me that the shaft is in two parts and I would only need the CV joint end that goes into the diff. So I think the way forward now is to get one and a new seal and see how that goes. So my question is has anyone ever split one of these shaft's and is it easy and does the shaft come out of the wheel hub easily or would I need a puller to get it out and a press to get it back in. The reason I ask this is because when I fitted the new seal last year I removed the wheel assembly and shaft in one lump.
Thank's in advance.
I believe it can be pulled by hand. That said I`ve seen Jagcare struggle terribly with getting a shaft out of an XF diff. As your one has been in pieces recently, I would suggest it would probably come out fairly easily.
As regards splitting the shaft to separate the two parts, I can`t really comment on that as I`ve never needed to do one. Have a good look on other Forums for advice. That might turn up some immediate clues.
To get the shaft out with the hub (quite feasible) separate top and bottom plus the toe rod nut and bolt. The caliper will need to come off the carrier and be tied up. Perhaps worth removing the disc to make things easier and reduce weight. You may find a cir-clip or similar at the CV joint end. That`s all I can surmise presently.
Best of luck. This has not been easy for you so far, Jeff.
No doubt if oldtimer was still with us he would be off to the local scrap yard grab a shaft strip it down and put all the info plus pics on here for all to see.
I had to do some remedial work on my old S-Type (sold on now) and put the article in the August 2017 edition of the JEC magazine.
One shaft came out pretty easy but the other was a downright pain in the a**e!!

I would have thought a good second hand unit via Eurojag or Andy at Auto Reserve with short warranty might be a sound, economic and quick fix that need not break the bank. EJ are great guys to deal with and prices always surprise me.
Apart from this problem the car runs great,it's just flew through it's MOT and I still get lots of pleasure out of driving it. If Bristol Transmissions could have re built the diff for me I would have bought a new OE shaft and that would have been it. but sadly they don't do them any more.
So there we have it. I don't' want to keep spending money on it and still have the leak. Incidently I emailed that company that you mentioned about the oil additive last week but as to date they haven't got back to me.
PS I could trade it in and buy a Mustang
