Rumbling/vibration through chassis and steering

[GavC]

As above in title. Tried a few things things so far... Changed various suspension bushes, new front tyres, wheels balanced, new brake discs and pads. Full belt change done recently too.

Any pointers guys?

Happening all the time ? Driving ? idle ? Revving ?
Have you checked your dogbone ?

Check various things like the drivers engine mount isn't shagged
Check the gearbox mount under the battery , they sag and cause the exhaust manifold to vibrate against the subframe.

Driving for is a definite, not sure on revving - I'll check tomorrow and let you know.

Those are 2 things that I haven't checked, what is tell tale signs of wear?

Driveshaft ok?

Accelerating ? Cruising ? Decelerating ? or all the time while driving ?

Last mechanics visual inspection didn't reveal anything obvious but wouldn't rule them out. Anyway to diagnose them?

Just the usual really.

Noise on lock.
But looking at them should point out an issue really.

I don't have noise on lock

I'll check this mount this week, how can I diagnose it being buggered? The dogbone mount was replaced lately too, perhaps I'll check this is still in place securely.

You say the dogbone was replaced recently, did you powerflex it? If so, that will cause more vibrations until it beds in a bit.

So the vibration isn't speed sensitive, which rules out a wheel imbalance. If it feels like its coming through the whole car (you can feel it in your seat?) it could be coming from the rear, so check for play in the rear wheels first off. If the rear discs have been changed check the spacer has been fitted correctly as well.

I replaced it with an OEM one

Wheel bearing?

+1 for a wheel bearing. Mine is making a horrid squeaky metal-on-metal grinding sound. I only worked out it was the bearing when I took the front wheel off and could see the ball bearings behind the ABS ring!

Turned out to be combination of poor balancing by tyre shop (no longer using them, they didn't say there was anything wrong plus I had my doubts about the guys working there for the boss) and perhaps the tyres not bring great, came on my 2nd hand turinis. They were continentals with ok tread all round. I was in a good position were I had new p zeros on my old wheels so I had these swapped over at a new tyre shop.
