This is the continuing saga from my last poisting - wheel bearing keeps failing. Today I tried to fit some new brake discs and noticed that one drive shaft was different in diameter to the other. So, I phoned up the cit dealer who had refurbished my drive shaft to see if he had made a mistake. He was adamant that he replaced the original. This can't be true surely! more importantly am I at risk?
Couldn't get one disc off - the holidng screws are siezed in.
Found Activa has 2 different driveshaft diameters

If the splined part isn't the correct diamter, it could have play on it, so that when the drive shaft drives, it could get out of alignment and try to apply torque in the wrong way, i.e. putting a load on the bearing that it isn't supposed to be exposed to.

Its quite easy to test : release the hub nut both sides and look for any unduly slack on the axle stub in the hub. It should slide firmly in/out (in fact tend to stick) - but not have the slightest sidewards movements.

According to the parts list from a Swedish internet supplier I have regularly used, the Xantia Activa hub has 25 splines while the standard Xantia has 15 splines - so I doubt you could even get the wrong driveshaft in there. The reason that the driveshaft are different diameters could be that one is solid while the other is hollow. I know this was the case on my '93 XM TD12. As long as the splines on the ends of the shaft are correct, the shaft diameter may not be that important.

exactly right, one size is hollow on is solid, should make no difference to the car. There is an active post on activanet.co.uk about this at the moment.
Nisk I've had a couple of people ask me what the TD12 is from memory in your contry (or just you refer this to the XUD11ATE/BTE which is the 2.1 L turbo D (in your case with it being a 1993 its a XUD11ATE). Could you just confirm this and it has aparently caused some confusion.
