Hi guys,
I have an old XJS Rear End.
Is there an option for to change hub carrier - Part No. P26698 to a new option that will bolt on?
Cheers,
Mark.

 

The hub carrier is bolted on. There are no other rear hub options. If your hub/driveshaft is unserviceable, the best option is to buy a second hand one.

 

Agreed,

You mentioned elsewhere its not a Jag car, no problems.

A snap of what you need might help.

This what I call the rear hub, although the snap is to sow the grease bleed hole, but I reckon enough is there to get the idea.

 

Welcome to the forums Mark,

I suggest you post photo(s) of what you have and what you hope to do with it. The Jaguar IRS is a regular for finding its way into other applications so there's bound to be a solution once everyone can understand the issue.

To clarify, are you asking if a new/different/updated/specialty choice exists?

I'm not aware of any, but that means nothing.

If nobody here knows of any choices you might also check out the websites catering to the Cobra kit car crowd and/or street rod crowd. The Jag IRS has found its way into so many other project/kit cars over the decades. I gotta think that somebody has been there and done that by now

Cheers

grant
i have been told that a XJ40 hub carrier might be a bolt on replacement for the carrier i have which looks exactly like the picture you posted
picture below is what im looking at to replace mine with




cheers

An XJ40 hub carrier that you puctured is not a simple bolt on to an early Jag rear suspension. The complete half shafts, hub bearings, fulcrum bearings, fulcrum bolt, and hub itself that the wheel mounts on are all different. In addition, the XJ40 hub assembly is designed for outboard disc brakes, not inboard.

XJ40 hubs with all of the above different parts and more are sometimes used to convert an XJS from an inboard rear disc setup to outboard rear discs. There is also fabrication involved to do that swap. That may be what they are referring to.

 

Mark,

That snap of mine is the hub unit from one of my S2 cars.

The Inboard brake outer hub is what it is.

YES, people have converted to Outbooard brakes, as mentioned, and used the XJ40 stuff, but the difference in attachment etc is like "chalk and cheese", NOT imposisble, nothing is.
Inboard brakes is what it is, and those hub units are unique, from MK10 right up, in so far as looking the same, I have never measured or anything else if there would be a difference from the 1960's to the last of the Inboard brake cars. I doubt it.

All the Series cars and XJS (Inboard) are the same, that I know. ABS cars, as in real late stuff are basically the same, just with an ABS sensor, which if the fitment has NO ABS, who cares.

They are Handed, for the purists, as in the grease cup faces the rear, a dirt ingress thing through the tiny hole, really??, otherwise no changes.

Do you have an issue with one, broken?, noisy bearings? etc.

 

thank you for the information
cheers

 

guys
i have found some numbers stamped on my diff and just asking if anyone can decode for me
numbers are T L79 3082
any and all help would be grateful
mark

 

Is that on metal tags under the rear cover bolts? If so, then I would expect a PL tag, meaning "Powr Lok", i.e. limited slip, and 3.08 could be the axle ratio.

 

the number given is stamped in the housing
the tag on the diff cover is 43/13 im assuming thats 3.31 ratio
just trying to work out if its open or powerlock without opening it up
cheers
mark

 

I don't think those numbers have any significance.

 

If the Power lock is working, then, wheels off the ground, turning one wheel forwards will make the other turn forwards also. An open diff will make the other wheel not being turned rotate backwards

 

3.31 is not XJS that I can remember/find.

Our XJ12 S2 Fuel Infected with the BW12 trans are both 3.31

XJS PreHE with the TH400 trans ran 3.07 LSD. I got one for our S2 Daimler 6cyl from a 11/76 XJS, complete with sway bar etc. 3.07 was the ratio for S2 XJ6 4.2 with BW65 trans.

XJS V12 manual trans, the 300 odd ever made, NO idea what ratio.

Still unclear what you are attempting to do based on a bolt on hub carrier to replace what is there?
Inboard to outboard brakes, already discussed, and NOT bolt on.
I know of nothing that would be bolt on for that arrangement.

Those ratios above are for Aust market, as I do know other markets got different ratios in some cases, for the same engine trans combination.

 

guys
im confused
as i have the diff out
i turn one side and the other turns opposite
then if i turn the input (tailshaft)both forward and backwards both wheels turn in the same direction
cheers

 

This is normal, the diff is not a limited slip diff. Assuming it is a GKN Salisbury it can be turned into one by replacing the internals (not the crownwheel which you keep, but the bits that is bolted to) by an LSD unit.

 

Thank you for the information very grateful
