V70 2008 vibration/wobble - Page 4

Hi Paul,

I was away few weeks. I'm 99% sure about drive shafts and support bearing. I will have on next week checked front and rear axle once again.

Shocks should be also fine, rear ones are brand new, Sachs. Lately I did also shock test, all four over 90% performing.

I noticed today, that on really low speed, on walking speed, I can feel how on certain place I'm like drive over some obstacle on the ground, small obstacle. Like there is a bump somewhere. I lifted up car and monitored all wheels by spinning them around, everything is perfect condition... What may it be? Can front wheel bearing worn down and give symptoms like this? Real Mystery!

If anybody has some idea, let me know please. Next task will be for me changing front wheel bearing I guess...

I go back to my original suggestion. I may well be wrong, but after your last post I suspect you have a bearing failure.

It won't show when the bearing is not under load (jacked up).

The only other thing I can think of.
I knew a lad whom regularly bump started his car.he had a low speed clunk develop, no obvious cause, all joints and bearings good.
After much investigation we found 3 teeth missing from the crown wheel. The regular bump starting had sheared first 1 then a second then a third tooth when the low speed clunk became noticable.
At more than walking pace it smoothed out and became un noticable.

Paul.

Hi,

Went and checked once again rear and front axle at the official dealer. No problems found, everything is good.

Is there a way, that I can temporary deactivate ABS & ESP on P3, so I could lift up the front of the car and "drive". If anybody know, how to do that, please let me know. Then will be possible to see, whats going on there.

Anyway, next thing will be front bearings to replace, like tommyweaves said while ago.

I think on the left stalk you can select DSTC and then choose OFF with the button on the end. Not sure how much it switches off though! I think it will default back to ON the next time you start the car.

drive shaft or wheel bearing maybe?

Hello, I saw you write about your problem in the forum's commentary. I have exactly the same problem
Have you found a solution to the problem? If you are, maybe you can help me.

Thank you,
