'86 XJ6: Most Annoying Task So Far...

![Default](/forum/images/icons/icon1.gif)
lubricating the rear suspension. One cracked fitting, with the end broken off in the hub carrier so I have to get an extractor and get it replaced; pinched my arm on a caster of my creeper (OUCH); grease going everywhere but where intended; I finally had to remove a rear wheel, loosen the clamps and slide the plastic u-joint covers back to access the Alemites, and even then it was iffy to get the grease in. Everything seemed to be in good condition, though. I only got one side plus the two inner pivots before it got dark. I also cleaned the aluminum hub carrier, but was not prepared to check the lube, so later. I cleaned the inside of the wheel well and the wheel and reinstalled, and came in to attend to my wounds and get the grease out of my hair. I plan to change the diff lube also.
I am planning the AC compressor replacement: I found a rebuilt GM unit for about $155; will replace the expansion valve, flush, and do the water pump and belts at the same time.
Two tons of pure British fun!

Good work!
Glad you disclosed "....so far..." in the subject line. There are a couple jobs you might face that go beyond annoying![Smile](https://www.jaguarforums.com/forum/images/smilies/smile.gif)
Before buying a compressor determine if yours has a "Superheat Switch" or the "HSLP (High Side Low Pressure) Switch". The difference is critical and almost undetectable, visually, if you had both type compressors sitting side by side. It would be a shame to find out *after* you've installed it. Some vendors don't know or mention the difference.
If you have the small (about 1.25" square) three terminal thermal fuse clipped to the compressor bracket, you have the "Superheat Switch" type compressor. One wire from the fuse comes from the a/c controls. Another goes to the clutch at the front of the compressor, and the third goes to the superheat switch at the back of the compressor.
Compressors with the HSLP switch don't use the thermal fuse. The switch at the back of the compressor has a wire that goes right to ground.
Yours should have the Superheat type....but, IF the compressor has already been replaced, it MIGHT have been converted to the HSLP type.
