Have had the car a month now and I'm told the rear teeth on the ABS ring are worn. I understand that on the 635 you cannot buy the rings separately but you have to buy the half shaft that comes with the ring at circa £100 each side ?

Can anyone confirm? - mines a 1989 car so one of the last made so getting any from a "breaking car" would mean they are likely to be just as worn ? or can they be reconditioned?

Any comments would be appreciated. - other than that the car runs perfect.

Hi, did you find a solution to this, I have just bought a car with this problem. I would like new rings, did you find new ones if so where, thanks

Hi Gil...welcome to the Forum

You can occasionally find an ABS ring of the right dimensions through some suppliers.

Here are some for other BMW models although probably quite similar if same diameter and number of teeth, etc
