OK Gurus,

i carried out extensive road testing yesterday, as with regards to shuddering/wobbling motion whilst driving, basically you can begin to feel the symptons around 35mph and continue into the 80's (i didnt go any faster), and when braking i noticed that the car shudders ( not a lot but it is noticeable).

I have had previously (a week ago, when i brought it) the tracking done and two new tyres on the front, complete with front wheels balanced too.

So guys, what do you think, have i purchased a lemmon  , shes only done 54k nice conditionnlots of toys etc, but i am worried she is gunna cost me a bomb to repair..

looking forward to your input, and if anyone lives around dunstable, who can cast an eye over it for me, i would be greatful

Regards

was it just the front you had the tracking done ,or was it a full geometry set up ?? 

[GT]

well i dont know know, they put a lazer on each wheel, and he said the front was out by 3 points or so 

[noel]

did this problem only occur after the tracking was done 
just another thought have they tightened wheels nuts up,should'nt happen but can.

warped front discs causing steering wheel wobble on heavy braking?
buckled alloy or defective tyre fitted somewhere causing vibration whilst driving?
i assume you have checked these items since you started the first thread ?

Hi

I have checked the alloys out, they are fine, i have had the front tyres changed, and when i checked the rear wheels the tyres looked OK

With regards to the discs, would this not have been picked up when the new tyres and tracking were done ?

How do i check the discs

ide check the front discs for scoring and un even wear,under heavy braking if you can feel the brake pedal pulsating as well as the steering wheel wobbling, imho, youve got warped front discs.best to change discs and pads at the same time..
always worth having the back tyres checked for bulges before balancing..

[GT]

i  will check to see if there is any pulsating, as well as steering wobble..

So if i get any pulsating, it could be the discs,

If i get steering wobble it could still be the balancing

Anything else,

Will report back as soon as i know

Regards

I had an egg shaped alloy that gave similar symptoms. It was only apparent when on the wheel balancer you could see it was out of shape as it was spinning

Knackered wishbone bushes can cause odd vibrations as well , worth having them checked although if you've had a full geo done if was somewhere decent they should have checked those as part of the alignment....

Worn/faulty dampers , also fairly easy to check.

Out of balance wheels are of course the obvious one, if the vibration is felt through the seat its the rears , if the steering wheel is wobbling then its the fronts. You dont generally feel the rear balance issue until you reach speed whereas front balance is usually obvious as soon as you are moving.

OK Eyes down Gurus,

After reading through all the comments do to with my problems with the wobbling etc, i took the car back to national tyres, and had them recheck what they had done, the list is what they found

>Tracking OK
>Front wheels out of balance my 15g & 20g, Rebalanced for free
>Rear wheels, well out of balance, now balanced cost £14.50

>Disc and pads on the front are worn, need to change them...

so we are getting somewhere gents, thanks for your help

Yesterday, car drove fine, infact lovely, today driving to work, the car is slightly vibrating/wobbling, what can this be... could the suspension be at fault... could it be something simple .... answers on a post card please

Describe the wobble in more detail. Is this a left right wobble through the steering wheel for instance?
