Body wobble/vibration under acceleration

[Nick Warwick]

Hi guys

I recently changed both driveshafts due to my drivers side causing extreme body vibration/wobble at speed. This solved the problems but i now have a very similar problem but this is now only on setting off acceleration.
It will only occur at speeds between 15-25mph and then disappear. Ive recently noticed one of my front top mounts knocking too which I'm suspecting isn't helping.

Can anyone shed any light on this?

My first thoughts are either suspension related or engine mounts, or even driveshaft gone defective?

Mileage is on 149,000

Thanks
Nick

I'd say you'd need to carefully check the tyres for being out of shape, and the condition of the inner rims (buckling) etc.

Engine mounts are another area to investigate.

Possibly the gearbox (torque) mount? When I replaced mine for the e-Focus one, the original showed signs of wear at approx 125K mileage.

All tyres are brand new as of last month, I've checked for any eggs but nothing present.
While i had the tyres fitted i had one of the alloys (now on the rear) repaired due to a buckle.

With this being the D5 engine and its current mileage i do think it would feel a lot nice to drive if i replace the engine mounts. How easy is this? has anyone done a tutorial?

Thanks for the replays

I buckled an alloy on my S40 T5 and got shocking vibration between 65-70mph, even when I had the buckle repaired the vibration was still there, although not as bad, it was solved when I changed to a new set of wheels, I don't think they can ever fully get a buckle out of a wheel and even when I had the buckle repaired it took them ages to balance the wheel, so I was never convince they manage to balance the wheel properly

Sounds very odd, I seem to recall have this issue on my other Volvo (a 2.0D) but at higher speeds than what you're suggesting.

This was rectified by changing the wishbones for new ones as the rear bushes were shagged to smithereens!

And most recently on my D5 it had a bad vibration when at speed, the dealer I bought it from had put a really worn tyre on it and once that was replaced and 4-wheel alignment was done the car now sails smoothly.

In regards to engine mounts - you can inspect the bushing on the top one as it sits above the alternator and timing belt area.

Other one is on the under-side of the engine - from what I gather the e-Focus torque mount does not fit to the D5 engine.

As you say, it could be hammered top mounts - did you get new ones when you lowered the car?


Hope this helps!
