Steering wheel vibration @ 95-105 kph

[MINT96SS]

I'm in NZ, so no Bob Jane. No locknuts, either. The stock nuts are torqued to 115Nm.

this happenend to me ages ago in my old vh sle, i got the rotors machined and put a brand new set of pads on it and it went away, could be worth a try?

Just get the front wheels balanced on the car - this will also balance the brake disc, wheel nuts, trim etc....everything that rotates.

This is the best course of action from the sounds if it. The machine can spin up much faster than the off-car balancers and will get the dynamic balance of the whole wheel assembly. Also chek that the tyre pressures are OK and the tyre wear is not irregular.

I'm considering slotted rotors and adjustable Konis for it anyway, and my link rods are clunking too.

But the 110k service is due first, so I'll get the front end THOROUGHLY looked over, including the rack, just in case I've missed something.

Driving home tonight it actually behaved pretty well, so go figure?????

Rule of thumb. Vibration under 80kph - front wheels/balance/front end. Vibration over 80kph - rear wheels/balance. Doesn't seem logical but that was the problem with my VS Calais.

If all else fails check the driveshaft alignment. A specialist would have to do this as you need a 'driveline inclinometer'. From memory this procedure is in the factory workshop manual. I think there are different lenghts of rear lower control arms to correct the angles if they are out. (im assuming a 5link rear end)
Could it be a worn uni joint throwing the tailshaft out of balance?

Are the left and right front tyre pressures the same? A variance will cause a vibration...
Worn shocks/struts can also cause a vibration....

Also a long shot, but a similar issue happened to a mate of mine's car, but it was at lower speeds it felt bumpy/vibrations as though a wheel was wobbling... problem was the wheel nuts were on the wrong way around (the pointy end that digs into the wheel was facing outwards) allowing vibration/movement....

I think my shocks are slowly dying a death. It gets a bit floaty at highway speeds, especially at 120ish.

I intend to replace them with Koni adjustables.

Unbelievable.

Ive just noticed similar issues with mine, got new rims on it 2 weeks ago, 1 week ago I gave a kerb in a frikkin carpark a fairl good thump with front left pass. wheel - 1 week old after never scraping a rim in years!! :doh: - $150 repair job there but thats another matter
I was on the freeway today and 95KM/H + the steering wheel starts to vibrate....pretty sure its the first time Ive been on f/way and that speed since the rims went on....just wondering if whacking the frikkin kerb in the carpark might cause the vibrations......i checked the locknuts and theyre all randomly place on each wheel so might try the opposite the valve theory

Trty swapping the front wheels for the rear - the tyre itself may be internally damaged.
