1993 XJS Salisbury Diff, Inboard, Differential Fluid Change
I would like to replace my differential fluid but am unsure the location of the fill hole. I have found the drain plug right on the bottom of the differential. Does anyone have any instructions for the job and the location of the fill plug? Also what is the fluid type and capacity?
I checked the pages in Kirby's book but didn't find much helpful information other than that the fill plug is not easy to remove.
Any helpful info is appreciated. Thanks!

It's on the rear diff cover, about half way up, right of ceneterline. Might be obscured by caked-on dirt.
A little tricky to get to, but doable.
I recall that removing the lower tie plate (gahhh...like 20 bolts!) makes it all a bit easier.
If yours has access panels in the trun, all the better :-). Mine didn't.

This is how I do it in my '95.
I have a hand pump that you can buy in any parts store.
This hand pump has a flexible plastic tube.
You also need a half inch drive ratchet wrench with a 3 inch extension.
Remove the right rear wheel, locate the fill plug, located where Doug described.
This is the fun part...
Attach your extension to the wrench and, reaching up into the rear subframe (you can do it) insert square end of the extension into the square hole in the fill plug and remove the plug. It's fiddly and a PIA but you can get your wrench and hand up in there. Remove the drain plug, drain the oil replace the drain plug and tighten.
Now, using your newly purchased hand pump; fill with 80/90 gear oil, isert the end of the tube into the diff and fill to proper level, replace the wheel and you're finished.
Good luck

I use any name brand 80/90 gear oil with a bottle of limited slip additive. Some gears oils already have the correct formulation for limited slip
Roger summed things up well. The only thing I'll add to to clean the filler plug area well so dirt doesn't fall inside the diff. And always remove the filler plug first, then remove the drain plug.
As I recall the diff holds about 2.25 quarts

Yep, that's it !
In fact, your Salisbury diff is kissin' cousins with the "Dana 44" diff used in scores of American vehicles
