Does anyone know how to remove a front abs sensor as mine won't budge
Yes sensor is faulty. Is there no way without taking the hub off?
Chances are it will disintegrate once you start to work on it. The hub is easy enough to remove. You can release the hub nut, then the splined bolts on the driveshaft (transmission). Turn the steering wheel and you should be able to drop the drive shaft down and out. That will give you peace of mind that no debris gets onto the reluctor ring, etc. Use a little grease in the aperture when fitting the new sensor.
Does it matter which direction the steering wheel is turned?
Will I be able to release the hub nut with the front end up on stands. Just put a couple of bolts back in and get someone on the breaks?
No, do this with the wheel on the ground. Take the alloy wheel cover off (covering the wheel bolts) and get an impact hex socket on it with a 1/2 ratchet drive bar. Some hub nuts are Allen bolt variety. If that's the case - then I can recommend Laser tools which are excellent. I use a length of scaffold tube on the bar for leverage.

Incidentally - there's no need to touch the strut pinch bolt, turning the wheel works. Another tip - don't hit the CV joint with a steel hammer to remove it from the driveshaft, only ever use a rubber mallet.
The GKN kits include everything. In my experience they're good for 2-3 years. Audi boots are better. Changing the boot on the CV joint is going to add another hour tops. Well worth it if you're removing brake components and driveshaft. Means everything will be sweet as a nut once you remove ABS sensor. Other main thing is that once CV boot splits (and it will) and normally when you least expect it, the CV gets contaminated (loss of grease and grit gets in) and you'll end up having to replace the CV too.Ok do you know where I could get one on its own? I can only find them as part of boot, joint or bearing kits and although the boots could probably do with changing I don't have the time to do them at the moment
Yes, I would.Do I need to take the caliper off aswell? Sorry for asking so many questions but this is the 1st proper job I have done on a car
