Hi,

Just gone and bought 3 new Bridgestone tyres (2 front, 1 rear, other rear replaced ~ 1 month ago) and had them balanced , fitted and tracking checked at a "National Tyre"... only cos they price matched tyre-shopper.com

However, driving up north tonight i've noticed a horrible shudder at ~65 mph but only when accelerating, or using a little power to keep the current speed up.

Now i'm 240 miles away from the shop that did it, so going to have to hope taking it back to a different shop will at least attempt a rebalance for free, see if that gets it, but this doesn't sound like just a bad balancing job, but i'm not sure. There was definately no shaking before the new tyres, but i'm wondering if they knackered anything while doing the tracking as, in their words, "it was stiff and took a lot of heat to move"...

Thanks in advance for any guidance,

that happened mine after i hit a pot hole few weeks back, fine at low speeds but at 100kph it shakes cause the pothole buckled the wheel:thumbdwn:, or else check that all the nuts are tight

doesnt sound like the tyres to me as they would shoulder whether you were accelerating or not, wouldnt they?....could be wrong though.

Correct, the wobble would always be there, but it would certainly be more pronounced when accelerating - if it was one of the front wheels (driven wheels) out of balance, as a rule though you can drive 'through' an incorrectly balanced wheel, i.e. wobble at 65mph, fine at 80mph.

Check gearbox and drive shaft damage (& wheel bolts), if you have even the tiniest amount of play in the drive shafts where they exit the gearbox you will have major problems....

if it's had tracking its possible a track rod end may have been left loose, seen it before but i doubt it would be that to be honest. worth taking it somewhere for a once over.

A wheel could have thrown a balancing weight as they are usually stuck on. This would cause a wheel to be badly out of kilter and this would produce a nasty shudder at x mph.

Either that or they've badly ballsed something up at the front end :rotz:

Just taken it back for a re-balance, looks like i had thrown a weight, but haven't got the car back up to 65 which is where it had started to woble.

Will be on the motorway for a test run in the morning to see if that's fixed it, and will let you know.

Had exactly the same with mine, wheels were out of balance.

it is joint a cv joint

had same symptoms on my cordoba had everything checked cv ect , then swapped wheels round front to rear and most problem stopped only could feel rear end wobbling in the end it was the tyre was slightly distorted so two new tyres and now car runs smooth, strange that the tyre centres balanced wheels and fault remained ...

Had similar problem it was miss shape tyre, balanced completely fine but on car a pig, over inflate and problem showed up under braking as well.

I had a slightly alarming incident on the M1 yesterday. Vibration and knocking getting worse over a few miles, only there whilst maintaining a steady speed or slowing, not there when accelerating. Pulled over, thinking CV joint or wheel bearing... Nope - very loose near side front wheel! :eek: Jacked it up and re-torqued and went around the others to be safe.

Moral of the story is when tyre fitters say be sure to re-torque your wheels after a few miles, it might not just be an *** covering exercise after all. I'll be doing so in future.
