Another thing to check would be the actual tyres having a weird wear pattern where the rubber cubes were wearing wedge shaped and causing a rumbling at speed . The tyres in question were remoulds and ever since I have not used remoulds.

You could have a prop shaft out of balance a damaged drive shaft or gearbox bearings then comes the suspension or engine,gearbox and diff mounting rubbers .
With wheels and tyres if you have a problem with the front you feel the problem through the steering wheel if its the rear you feel it through the base of the seat in other words your backside.

Seems possible, I was thinking drive shaft or CV or the vibration damper that autos have on the drive shaft but, I would expect to feel this through the steering wheel? One other clue that might help is that when accelerating through 55 to 60 the vibration is more than when on a trailing throttle. Also no vibration if going downhill at 55 to 60, so it seems load/torque related.

I thought you would like to know it’s fixed! After the garage ordered the wrong, reconditioned, part they found they couldn’t get a reconditioned one. Neither could they get one from a scrap dealer. An off side drive shaft for a V70, T5 auto is rarer than rocking horse droppings it seems. So after paying an extortionate £460 for an exchange Volvo part, plus £50 fitting, the vibration that plagued the car for a year is finally gone. Many thanks for your ideas.

This appears not to be an AWD V70 so no propshaft. Check your drive shaft bolts at the hub. Regards Peter

I have just had the car back from the garage. I explained all the symptoms to them, this is the third time it's been in, and that there is now a new set of wheels and tyres on it, the car has been 4 wheel aligned, twice.I have I also replaced the spark plugs. I had it serviced and they checked it over once more by the garage.
They say that running the engine on the data logger does not show up any faults on the ignition coils. Although, under heavy load, a gearbox warning light came on and a gearbox fault showed on the logger, there was jerking when a gear was engaged. They don't know if the problem is gearbox, drive-shafts or something else. They say the auto box on this model is its weak point. They think it may be a sticking solenoid in the auto box and it is as expensive to get a recon auto as to repair the solenoid.
They have some drive shafts from a scrapper (80k mikes) that they can fit for about £300, which MAY solve the problem. If it is the gearbox they say a recon one is about £1800.
I was thinking about some gearbox additive. Any ideas welcome.

You may have a damages rim either inner or outer. The balancing can compensate for the error but not the out of round aspec. You need to have all 4 checked for roundness on the inside and outside edges. Also bear in mind it is the bead roundness that is important and will need very close inspection. Regards Peter.
Thanks for the idea Peter but because I've switched front wheels to back and back to front and had ALL the tyres replaced with no change at all in symptoms I don't think it can be wheels/tyres. Although because they are speed rather than engine / gear related I'm inclined to think it is something to do with suspension / drive

Check all engine/gearbox mountings for failing rubber and delamination of rubber/steel boundaries. Common on older cars.
Check with steel bar and try to move mountings. Chances are they are soft in an 11 year old car.

Other way to test out of balance on drive wheels is to sit the front up on axle stands. Chock the rears and run it with the wheels off the ground.
This can also be done removing the front wheels and that takes the wheel / tyre balance out of the equation.

PS It looked as though the Tripod bearing, which the auto only has, had slack in it.

Thanks Peter. I've now changed all the wheels, the new ones are perfect. New tyres. Still has the shudder. Goes in the shop Thursday.

I once had a Ford Sierra automatic which did this, and the problem was traced to a partially seized front brake caliper. Once this was replaced, the car shuddered no longer. Might be worth checking in your case.
