Would be interested to see what people think might be responsible for this:
Was driving to my parents this afternoon on the M60, doing a steady 80 on cruise. Had just passed someone and pulled back into lane 2 when all of a sudden the front end started juddering quite violently.
So I pulled across to the hard shoulder and had a quick look around, although as I slowed and pulled across I noticed it stopped doing it. Couldn't see anything wrong when I got out. All 4 tyres pointing the right way, all wheel bolts in place. No sign of a deflation, and no warning from the tyre pressure monitors.
Decided to try making my way to the next junction and it was fine. Took it to 50, then gradually up to 70 and no sign of any bother. So I stayed on all the way and crept back up to 80 to test - no bother.
Looked further when I got there and no obvious sign of anything wrong. Just come back and all's well.
I wondered at first if it could be a wheel weight that had come off and then whizzed out of the wheel as I slowed. It's hard to tell if it's that - all wheels have weights on, some at the front and rear of the wheel. There is residue on some wheels from weights but it looks old.
Only other thing is that maybe something temporarily got kicked up into the wheel. It happened literally as I went over the cats eyes.
Anyone else got any ideas?
