XK8 differential oil change, easier way
I just changed the differential oil in 98 xk8 the easy way. Didn't have to jack the car. Took less than 3 hours. And most of the time i was sitting in a chair. Here are also some pics of the aaahhaaaa moment for getting access to the fill plug.
I also got 4 videos on you tube.
I thought this DIY was awesome and had to post it. Thanks Chris

hardest part
The hardest part of the job is putting the fill plug back in. For fear of stripping threads, i used some modeling clay on a long screwdriver to get the plug started. The wobble extension couldnt get the plug straight. After it started it was no problem to tighten with the 1/2"drive wobble extension.
Next hardest was making the videos.

So, if I understand correctly, the drain plug is easily reachable. So it is easy to drain and inspect the fluid. With your approach, the fill plug is now reachable easily, too. So, the diff can be filled back up. Would you mind sharing what you filled the diff with, and why? Thanks.
PS: Definitely not looking to add anything on my to-do list, but I might have to, now.

diff oil
Since the shell spirax 90ts oil is not attainable, i went with valvoline fully synthetic 75w-90, with "extreme high/low temperature protection".
From reading another post, a redline rep said his product will be comparable to the shell oil. So, i ordered some redline 75w90 but it didnt get here in time. so now i have two quarts sitting on the shelf. it is also fully synthetic.
The car has 180k miles, the oil was dark gray/brown to blackish coming out. I took out almost two quarts with the hand vacuum pump. And put in the 1.9 quarts of clean oil with a funnel and hose.
Anyways if i screwed up with the oil and someone has two quarts of the shell let me know i can change it pretty easily.

What a great idea, it's going to be my next job, thanks for that chrisgski.
I've been looking for the right oil that's recomended by Jaguar, and it seems quite difficult to find, but I went SNG Barratt with the part number JLM20255 and they had it in stock, it arrived today.

Bet you the supplier is Fuchs/Silkolene and same as their Race 90.

2 Rubber Grommets Without Hole - Rubber Plug - Solid Grommet 1 1/2" Diameter
Chris, This might be a better idea for the hole. You can have easy access again and a little sealer will water proof it. I'm sure a larger one is available.

Been there done that! Piece o'cake
Yup -I've been doing this way on both our XJ8 & XK8 for yrs- on our '98 & '00 there were actually access holes already there covered with color matching patches, grind those away , then to make it easier use knibbler to make access openings larger for hand, then once done treat & seal it back how ever u see fit ( I use aircraft quality tape cause here in Phx it dont rain or snow much!)
Cheers!
Cheers!

Right, just tried to change the diff oil, trying to work out where to drill access hole, it seems a later car is slightly different, so jacked the car and had a look and there's a support plate holding two stays/ struts blocking the filler plug, so you'd have to drill that one to, but I'm not sure about that because it make a bit weaker.

second differential oil change
well i finally got the oem correct differential oil from SNG Barrat. Ordered on July 30th recieved aug 20th. Changed the oil again. Piece of cake, took less than 2 hours. And 1.9 quarts means 1.9 quarts. Had to clean up the floor of .05 quart. LOL.
The oem "final drive thermal 90" oil is a lot thicker than the valvoline 75w90. I noticed the slower pour rate in the funnel. So i recommend the thicker viscosity oils like mentioned in the above post. (90-140s) Also the valvoline oil after roughly 1000 miles turned from nice yellow color to a colbalt gray black color. It kind of surprized me how dark. Which may be it just mixed with some of the dirty oil and gears inside. Dont know.
Nevertheless, i have the correct oil in it now, and hopefully it will last another 180k.
