Alignment Issue

[MIVEC]

Hey guys,

For a while now my car has had alignment issues in that the car always pulls left as soon as the wheel is left to itself. Obviously the faster I'm going the more noticeable this pull is. I've had it aligned numerous times and also replaced the front bearings in the hopes that this would fix it. My suspension shop seems to think all my bushes are in order and can't seem to pinpoint my problem.

The worst of it occurs whenever the car is taken above 100kph. The steering wheel starts shaking pretty crazily and makes any sought of trip in a 100 zone a bit annoying as I get jelly arms at the end of it and sore wrists.

From what I've heard elsewhere warped discs might be a contributor but I'd imagine that'd only be the case in a braking situation rather than just driving. I'll be getting new discs/pads soon regardless but I'm interested in any other ideas of what might be causing this.

Control arms maybe?

Any help is greatly appreciated.

Pete

Um what are your tyres like?

When I bought my old R33 the tyres that were on it were 'feathered' which caused the steering wheel to vibrate quite bad at speeds above 80km/h or so (felt normal at 60km/h). I dont know much about it but basically the tyres wear unevenly (due to misalignment) and you cant balance them to fix the problem, so although they still had good tread I had to get new tyres which fixed the problem (and an alignment to stop it happening again).

Just something to check. Good luck.

If the road cambers to the left, then the car will steer left.

Have you ever rotated the wheels so that the wheels swap sides, ie left -> right, right -> left ?

Try swapping the fronts to the back (unless of course you have different width wheels front and rear) to see if the problem persists.

Are the wheels sitting on the hub centring rings? Or sitting on the wheel studs?

[MIVEC]

Yeah I've got wider rears than fronts so that options out.

The tyres are brand new as are the rims they're sitting on. They've been balanced and problem persists.

An additional note, whenever the car is hoisted up the problem disappears for a few days before reappearing at a slow pace.

Aiks! Mine seem to have the same problem but it pulled more to the right and find it harder when turning on long sweeping left hander. But now its getting much more twitchy after installing the Cusco adjustable camber arms (front & rear), Cusco tension rods and Nismo Swaybars.

Alignment check seem ok. Think it could be the bushes?

That's what everyone else I've spoken to seems to think. I'll bring it up when I go see the shop next.

Thanks guys.

I would love to find out the cause of this problem. I am still running the crappy 225*50*16 compliance tyres that my car came with so it may be due to shitty tyres. Above around 130kph it gets bad bad scary vibration and also pulls to the left but not badly. The shock is transmitted through the steering wheel but dosent seem to affect the cabin which is strange.
