Default 1996 XJS U-Joints

In my efforts to stay on top of repair issues I am considering to replace all of the U-Joints . Can someone please tell me the total required and if they are all the same?

My guess is Six (6), 2/rear wheel, 1 at trans and 1 at rear axle.

When I crawl underneath I just want to do it one (1) time!!!

As always thanks for your help

Not that you asked, but I'd suggest reconsidering

Anyhow, I recall the 4 u-joints at the half shafts being different than the u-joints for the propshaft/driveshaft. Yes, six total.

Cheers

As Doug said, the UJs on the rear axle are not the same as those on the propshaft. The axle ones are stronger and if you use propshaft ones in this application they will fail.
There are 6 in all, 2 on the propshaft and 4 on the axle.
If your rear axle UJs are not grumbling, clicking etc etc, then they are fine: just grease them every 3 or 4000 miles, and the inner fulcrums and the outer fulcrums and all will be well. There are 10 grease nipples in all. The propshaft UJs have no grease nipples.

Why are you suggesting to reconsider???

Is there something special about changing these U-Joints VS the likes of other vehicles including the half shafts on the older corvettes.

Thanks

Paul

You didn't mention any actual problems so it sounds like money and effort expended for no particular reason. And it ain't a 15 minute thing. U-joints are not a maintenance item. You replace 'em when and if they fail. My '85, 180k miles nearly, has 7 UJs. Six are original and still in great shape.

Do as you wish, of course . But I hate to see someone go thru all that work if it isn't really needed.

Cheers

Ok, this is new to me. Iíve had this particular 96 for five years and 60,000 miles.....never greased up anything at a nipple.

How many grease points do I have....other than the 10 you just mentioned? I suspect Iíll be objecting grease into those points in the near future. I have some synthetic stuff I used when i replaces the hub bearings a couple of years ago.

Facelift U joints are different. They're 1300 series and they do not have grease nipples. It's a common Ford / Volvo item. It's also sealed and has lifetime synthetic grease. I've never seen a bad one. That would be consistent with Ford's strategy for its brands including Jaguar... a single part number for a multiple products and applications, economies of scale saves cost.

There's two on each shaft and my recollection is there all the same. So that would be six.

I replaced the U joints in my car with Corvette which are sealed.

I agree if they are not worn do not replace them.

The u-joints you’d end up buying at AutoZone are junk compared to the kind Jag used..., Birfield brand if I’m not mistaken...

I thought Jaguar typically used Spicer? But, whatever brand, it's a fair bet it was high grade

And, yes, you gotta be a little careful in buying UJs. Not only in terms of quality but in terms of design. Lots of different part numbers will fit into place....but look at the "X" section. Some sellers offer a UJ that fits ....but is nowhere near as robust in the center "X" section.

Right, Birfield owned Hardy Spicer, and a bunch of other brands before they were bought out by GNK. They are Spicer... good quality stuff. Beats the pants off “Duralast”
