Replacing ABS reluctor rings

Morning all, had a few lights come on related to abs/dsc/traction control and code reader pointed to right rear wheel speed sensor. I've bought a new sensor but when I took the old one off notice it was scuffed and on closer inspection the reluctor ring has corroded and cracked. Ordered a pair of reluctor rings and I'm going to have a crack at replacing them myself so I have a couple of questions.
First, any tips to get the driveshaft bolts undone as they seemed completely solid when I had a go yesterday.
Second where can I buy replacement bolts on their own or am I ok to reuse if torqued correctly?
Cheers
Sam

Garage had a look and said 9 out of 10 times the shaft is seized in the hub (dont I know it!) and i could be looking at 4 hours labour each side plus new bearings probably... to the tune of ÂŁ450! [emoji44]
So I've bought a hub puller and I'm hoping that will free the shaft!
Think it might be about time I bought an impact driver to save me a load of time!
In my experience it's 1 in 10 that's siezed

I thought mine was but I've managed to get it out now without any damage so I think they just didn't fancy doing it to be honest. The job wouldn't have been that hard with the right tools and a ramp, couple of hours tops!

Good Man. :thumbs:
Thanks Marco, seems all is not well though as I'm still getting the orange traction control light on it's own with code CC-ID 35. Haven't had it hooked back up to code reader yet so could it just be the new sensor is faulty.
I haven't done the n/s yet so there's every chance it could be that side now.
Brakes seem better for some reason too but that may just be in my head [emoji848]

Well finally got the driveshaft free from the hub this morning with a bit more punching. My wheel bolts weren't long enough for the hub puller of course! [emoji19] but hey it's out!
Here is the offending ring, cracked as you can see

So far no bearing damage so a very nice saving of ÂŁ450! Well happy. I think I'll leave the passenger side until it gives me a problem though [emoji23]
Thanks for all your useful info!

No luck getting the shaft out of the hub so it's off to the garage for them to have a look and see how much it will cost. If it's going to be a fortune I'm going to buy a universal hub puller and give that a go. My only concern if I get it out is will it go back in easy enough?

I had my local garage replace my passenger side abs ring and it ran me ÂŁ400 for parts and labour so if you can do it yourself you could save a penny or two. I will be doing it myself next time one goes!
bloody hell ÂŁ400!

my local only charged me ÂŁ120 to swap it over and think it was about another ÂŁ50 in parts for a ring and padgid sensor.
I'm hoping it will be closer to ÂŁ120, was that for one side or both? Surely on a ramp it shouldn't take longer than a couple of hours?
it was just the one side, think it was a couple hours work for them to get it all done.

Yeah I was robbed and the idiots put the cable for the wheel speed sensor back on too tight so it kept unplugging itself :rollseyes:

Managed to get all the bolts undone, hub but off, but I can't get the shaft free from the hub? Is there anything I can try without damaging any parts? If not it's booked in at the garage on Wednesday but I had hoped to save a few quid by doing it myself.
Plus Gas, lots and lots of Plus Gas.

Let it soak for hours to penetrate, then give it a whack with a plastic (or other soft) hammer
It's currently soaking in Plus Gas so I'll give it another go tomorrow, fingers crossed. If not I'll just have to fork out for garage fees [emoji30]
