I removed the front wheels on my XK8, removed the bolts retaining the speed sensors, removed the wiring connector but I could not budge the speed sensors. Everything I have read just says 'remove speed sensor' but it was impossible. How do I get them out? I didn't bother trying the rear wheels.

 

John, they just slide out. At least mine always did. I wonder what's binding yours. You did remove the hold down bolt right? As I recall it is 1 bolt per sensor.

if you missed it, no worries just let us know if you need help spotting it.
**edit- sorry John it was late, I see you pulled the bolt.

The speed sensors probably haven't been moved for a decade or more - on my car they were stuck solid, but will come off eventually.

 

As said in the original post, I removed the bolts but the speed sensors would not budge. I tried to ease them out using a flat bladed knife, I gave them a dose of WD40 and left them for an hour and I tried to tap them from the other end using a very large screwdriver. Neither front sensor would come out.

 

There are much better things than WD40!! (The clue is in its name.)

 

 

The sensors can get road grit between them and the housing. Sticking a pressure washer nozzle in there should dislodge it. If that doesn't do it, you could try a strong solvent such as lacquer thinner to dissolve the crud.
