Caliper removed, no apparent wheel bearing play or anything fouling the caliper/disc set up. Noise still there and some "notchyness" felt whilst rotating the disc.
Seems more and more to be coming from the wheel bearing.
Refitted brakes and checked hub centre nut. Not loose so loosened off.
Cv joint moved in the hub so not stuck/seized in there.
Pushed back shaft against spring and rotated disc, noise seems to be coming from the wheel bearing area.
Undid all nuts etc to allow cv joint removal from the hub unit, and hub unit removal from the car.
I had to sacrifice the anti roll bar drop link as the nuts where well and truelly corroded on. No flats on the ball joint shaft on these plastic drop links.
Cv joint out of hub unit, noise still in hub unit and notchyness felt, so a wheel bearing problem.
Hub unit hub removed and bearing balls and cages removed from the hub. Bearing outer races still in hub as circlip well and truelly corroded in.
Etch marks from plastic cage clearly seen on inner race "inner race" and on other surfaces, which would account for the loud noise.
will post pics when all of the bearing is out of the hub unit and ready for installing new bearing assembly.
Some water must have got past the rubber seals and the idle time between Jan and april withn the car stationery for that time, added to any "etching" and resultant bad noise.
The wheel bearing on the off side front may also be similarly effected, but one side at a time.
No issues with rotated shaft in gearbox heard but the acid test will be when I next drive the car I suppose.
The strut is off the car and the top turn plate checked, all good. Time to strip the strut down, fit new top gaiter ( if I can get one as the one on it is torn ) and paint the parts before re fitting. This is a job I have been planning for a while but not done as I knew the anti roll bar drop link nuts where gunna be a problem. The are not a problem now apart from the cost of a new drop link.
The hub abs sensor is well and truelly stuck in the hub so great care is needed, else a new one of those as well. I'm having great fun!!
