Volvo S40 - trembling car on high speeds

[fmalina]

Hi,
I own a Volvo S40 (Diesel, 2.0 Engine). Up until recently it felt in the car like on a sofa even on high speeds.

Although after the last MOT, I feel the car is uncomfortably trembling from above 60MPH (no matter if its on 5th or 6th gear).

What could be the problem?

Thank you

the tracking could be out?

I wouldnt think its that expensive to go to a tyre place and get it checked

Oh yes, that sounds very likely. We'll check it out. Thank you

Hello,
I'm having what seems like the same problem with my Volvo S40 (petrol, 2000 reg). It started a few dayus ago, and getting worse. I changed the rear right tyre as this was losing pressure, but no change. And now I've noticed that the car is leaning towards the right at the back. Can hardly notice the lean at the front.

Anybody who knows a little bit more about cars than I do (not very hard at all) have any ideas as to the cause ? I'm getting it seen to later today.

I also noticed when changing the rear tyre that there's a disc behind the brake disc that's completely rusted and crumbling to pieces the minute I touched it - see photo. Again, I'll point it out to the mechanic, but does anyone know if this is serious or not ? Surely , can't be good !

Many thanks !

Cheers.

Resuscitating this one...

I've got a T4 and had the same problem, now fixed:

Put the car up onto a ramp and with my hand turned the wheels on all four corners, the front left would stick at every revolution.

Essentially previous owner had installed cheap disks (service history shows he paid through the nose for them too!) and the front left disk warped resulting in wobbles at high speeds and under braking. Installed Vovlo disks and problem solved
