I've got the ~~wobbles~~

[Welly]

Having had a wheel balancing issue at 70mph ever since I had to replace 'that' tyre which suffered an express deflation that day; I surmised the grubby little tyre place (nice but a bit in the dark ages) weren't too hot with the old wheel-balancing skills.....

Finding a shiny new place in town I thought they'd have a sparkly new balancing machine and could 'do' all four wheels for me, which they did, for £18.00.......and........I get a 'new' wobble at 80mph ........go back a week later and they admitted their sparkly machine was out of balance itself and has just been re-calibrated and they would sling all the wheels back on the machine and do it again free of charge.......great I thought.........until the wobble remains

Now 99% of the time a wobble or vibration through the steering wheel is the balancing or a buckled wheel or flat spot/bulge on the tyre (they confirmed my wheels rotate good and true beforehand) so can anyone advise on what I might be missing here? I've had new wishbones 5 months ago so the ball joints and bushes should be good, new ARB drop-links and new top-mounts.

Could it be a wheel bearing? brakes binding? or simply bad balancing? find yet another wheel-balancing operative?

This is driving me insane now, I have to drive at either 70 or 95mph now - starting to get angry looks through my village

I know some cars really need the wheels balancing on the car,i ysed to have an old Vauxhall years ago and i had to have the wheels balanced on the car as that would be the only way i could stop the wobbles.

some tyre fitters dont balance wheels properly,
or another thing ive noticed they dont dip the wheel in water after putting new tyre on the rim,

igo to the same tyre fitter all the time now, theres too many monkeys out there

Having had them balanced twice, is be tempted to lift the front two corners and see if you can feel any play. If you're only getting wobble at those kinds of speeds, chances are its only a little play somewhere.
If everything feels tighter than a yorkshiremans wallet, try rotating the wheels - fronts on the back and vice versa. If the wobble goes, you know its down to tyres and not running gear.

I've seen wobbles at 50mph on a 7 series being suspension subframe related.

Got to agree with this, except the Yorkshireman's wallet, I have family in Yorkshire....but there again.....

These things can be misleading too. I've had two instances where what I would have sworn was a front wheel balance issue actually turned out to be tyre flaws on a back wheel.

Still nightshade's approach would track that down too. Does the Volvo have a 'proper' spare?

Not the 'dangerous' brakes, is it?

Thanks for the input, some good ideas going.

Think I'll have once last go with the tyre operatives and then move to 'Phase 2' looking for wear

I've been driving for 23 years and have had more sussy trouble in the last 5 years than in all the others put together. Must be our shitty roads

no wheel wobble on this one, http://www.youtube.com/watch?v=RGY3qUJN ... re=related 700 horses

ask to have the wheels balanced on the FINE setting, and can you find out roughly how many weights they have put on each wheel...

[Welly]

Well, they've/I've found the problem at last.......





Knackered Steering Rack well, the O/S Inner Track Rod to be precise. I've seen these can be bought separately so hopefully can get one fitted without disturbing the Rack too much. Any main dealer would say it needs a new rack at great cost so I'm hoping I can do the cheap fix or I'm screwed

Grabbing the wheel at the 9 and 3 O'Clock positions then whole thing rocks from side to side by about 5mm hence the 'wobbles'

[steve_earwig]

It had to be something like that I don't know how them Ovlovs are put together but I'd have thought that it was pretty likely the rack has to come out (Haynes: 1. Remove boot lid...) so I hope it doesn't come to that. Let me know if you have any problems sourcing, I can get Goran to look stuff up

New Inner and Outer track rod fitted Monday and the wobble is still there (a bit)

Needs Aligning (again) but I still think the balancing needs looking at, either that or there's a kinda 'soft spot' in the tyre structure

New rear discs/pads are on and they've been running pretty Hot, I've checked for binding and they're fine, I am reassured a bit as a Volvo Tech on the Forum said my model does run the rear brakes quite hard - to the point of wearing the pads at the same rate as the fronts

Then you're probably right - can you swap em all in turn for the spare?

It's all relative, I guess. I seem to get 40k plus from the fronts and don't expect I'll ever find out with the rears. Maybe Dai's had his long enough to change em twice?
