Wheel Wobble...

[DJones]

Andy, have the wheels been refurbished, if yes check the large centre hole where it mounts on the driveshaft, particularly if powder coated as they often won't be centralised because of the paint between the mounting face and you can't get rid of the vibration until you clean it all off.

So 525 miles over Christmas, with plenty of motorway driving around wobble speed Need to sort this out. I'm changing the front brakes soon so I'm hoping that they're part of the problem as they judder a bit and it all seems in phase when you brake during the wobble phase. It also seems to change with left and turns, which I've had with the 996s before. I'll be trying some different pads as the DS2500s are prone to juddering if the car is left outside and the discs get Rusty, which they always do, leaving a pad imprint.

Does it increase under load eg in higher gears. I've had this on cars with worn inner cvs.

No, was worst on the motorway at steady 80.

I've also experienced this on a MK2 GTI.

I think I'll need to get some wheels that are known not to wobble and try those first, as that'll rule out the wheels. Be odd for both sets of my wheels to give the same results but not impossible I guess.

DTI and a magnetic base should be easy enough to try too.

Could be something simple like a buckled alloy?? Had that on mine got the buckle removed and alloy rebalanced and problem solved?

Might be that the CV joint are dry and need re-greasing. Had that twice so far with inner CV joints.

Had an annoying wheel vibration through the steering in my Merc for over a year. Both front alloys were straightened and balanced, all the suspension was checked and even looked at engine mounts. Nothing found. Changed all 4 tyres and hey presto it's gone. The rears where unbalanced and with a slight bulge which sent the vibration through the driveline and up the steering column. Even if I rotated the wheels it would have felt the same.......

Discs and drive flange are easy enough tested for bend with dial gauge and magnetic stand if you have them. how clean are the mounting faces, could cause run out too.

Could be prop centre bearing. It made a he'll of a noise in my typ85 90 at about 60-70mph. I packed it full or sikaflex and it helped. I think driveshafts have to be seriously out of balance to feel it due to the small diameter and relatively slow speed.

The ramp technique has helped me find stuff like this before. Mind your self on moving parts obviously.

Have you got access to a 2 poster ramp at all? Lift her up in the air and have somebody 'drive' the car while you have a look for wobbliness underneath

It's the same on 2 different sets of wheels and tyres, so while it could be that they're both out, I had one set balanced recently and it made very little difference. Happens as you hit motorway speed, so about 60+

The discs do get a bit of corrosion on them, wit the car sat outside, so they're a possibility, especially as the DS2500s are quite soft compared to say a Yellowstuff EBC.

Anyone know where to get driveshafts refurbished? I can paint them etc. but I'd like to make sure they're in balance.
