Hello.
Can anybody shed some light please.
Between 40 and 50 mph my front wheels wobble. Especially when going in a straight line. Under or over those speeds it's fine. I have bad the wheels balanced, they are not buckled and no bulges in the tyres.
Its becoming quite irritating now especially as I'm using the car a bit more now the weathers nice.
Any help would be appreciated.
Cheers,
James

I've had wobbly wheels only between 60-70 before on my daily driver. I had everything rebalanced and double checked, and it ended up only being the crappy tires that were on it. The sidewalls weren't faulty, just simply weak. They'd buckle when driving at certain speeds. I have new tires on it now and it is way better. Perhaps that's it?

My V66 has had an annoying wheel wobble since I bought it last year which I have been trying to solve, as yet unsuccessfully. It starts at about 45 mph but varies in intensity depending on road surface and is worst in the straight ahead, ie steering linkages "unloaded" it seems to improve over 50 but is in fact just getting more frequent and a bit less noticeable but at high speed the steering is vague, particularly when braking heavily. The parts I have changed in the last thousand or so miles, in order, are; tyres, wheels, anti-roll bar drop links, reaction rod rubber bushes, shock absorbers, shock absorber top mounts, bottom ball joints, and finally the rubber coupling on the steering column. The latest attempt is to fit new bearings into the steering rack and rebuild it, this is now done and the rack will be fitted and tested this weekend. I'm hoping for a result as the guys at the Daf Hobby day last month seemed certain that this would be the problem and the old bushes were pretty knackered when I took them out. That and the fact that I'm running out of things to replace now... I'll post again if this solves it.

As you siad, you have replaced most of the usual suspects. Hopefully that will resolve things for you.

Either that or it's time to attack it with the on-car wheel balancer.

So.. After rebuilding the steering rack the wobble was much reduced but still there and noticeable from 50mph. The only rubber part of the suspension that I hadn't replaced were the inner suspension arm pin bearings but the Dutch guys tell me that these NEVER need changing. In desperation I fitted the new tyres back on to the original steel wheels and tried those. The drive is transformed! No wobble at any speed and the handling is so much more precise. I'm pleased that I have tracked the fault but not happy that my redrilled wheels are obviously not right. The wierd thing and what distracted me from the alloys was the fact that it wobbled when I first got it and on the original steel wheels so I assumed that it must have been something else.

Thanks for the update, now the question is: In what way are the alloys not right? Concentricity? Side to side? Warp?

I reckon concentricity, the sleeve bolts I used weren't the nicest quality and when they were drilled out to be tapped M14 there was a concern. One of the Dutch guys, Andy, is using conventional type wheel nuts but on new M12 studs and has had the Renault alloys welded and redrilled with a conical taper to suit the nuts. These would self centre which my sleeve bolts won't and I think this is part or my problem, his method is a much nicer solution. I may update the Renault alloy wheels thread on the DOC forum with photos of his setup if he doesn't mind.
