Bad Vibration care to guess the cause.

[flango]

The Volvo has been out of action 2 days this week due to a very bad vibration which needed investigation, let me explain:

The vibration came on at 65 mph and just stayed there could not drive over it at all, at 75 mph it was so bad the whole dashboard would shake and the vibration could be felt throughout the whole of the car, felt as though it was going to shake itself to pieces. After looking at the obvious and Several phone calls to the local dealers to see if they had ever seen it before and phone calls to Volvo technical no one could shed any light on it.

Anyone care to have a guess what the problem was and it's not particular to the Volvo could happen on any car, I'll buy the closest a pint at the next GTG

Crashing down a pot-hole in the road?

 

[flango]

Nope, that was my first thought too

Has it recently been off road? Had dirt stuck inside the wheel of my older ML with the same effects on the motorway.

Undertray.

 

[verytalldave]

OK then, seeing nobody else wants to play, then I'll have another guess.............
Faulty shock absorber......

 

[312 Sprinter]

Frozen water in one of the tyres?

 

[C240Sport97]

rear tyres worn

or

rear wheels out of balance

 

[brucemillar]

Old Lady with Zimmer Frame hanging on under the car.

 

[camerafodder]

Loose panel under the car?

Ignore that, Corned beat me to it!

 

[flango]

C240sport97 is kind of close with his first guess but it just needs expanding on.

 

[C240Sport97]

buckled rear alloy

 

[flango]

buckled rear alloy

nope, stick with the tyre theory.

 

[adilhk84]

Nail stuck on inside of tyre?

 

[camerafodder]

Bulge in the sidewall or perhaps something big stuck in the tyre itself?

 

[brucemillar]

De-laminated tyre.

 

[flango]

none of the above, need to think more obscure

 

[SL300-24]

Propshaft coupling...

 

[Deleted member 37751]

Loose wheel-nut/s?
