Wheel/car Shaking Between 108-120km/h ?

[I GOT RICE]

hey guys, my R33 keeps shaking including the steering wheel only when im doing between 108km - 120km then after that its fine. I just got the car alligned and balanced and it fixed it for the day then its back to its shaking self again after the next day.

any suggestions?

Tail Shaft maybe. Damaged wheels?

Check the virtical control arm between the upper and hub for play. The load bearing in there may have play and cause vibration due to wheel instability. You should also check your castor rods to see if the bushes are split and leaking oil. Failing that, I would be looking for a strut failure or leak.

Just a thought but the weights from the wheel balancing hasnt come off has it? Happened to mine and since it fixed itself for the day maybe it came off after the day.

When they did the wheel allignment the bushes were leaking a bit- but they tightened it up and said it was all good.

sometimes poor quality chinese tyres can cause this too

If all the wheels are balanced, i would be checking the steering rack bushes or check if there is play in the rack ends, ive just a real bad case of the my friends car shaking very violently, found the steering rack bushes were disintergrated and tightening them wouldnt do a thing. You can get these bushes of ebay, pretty cheap, look for d-project bushes. hope that helps

Take it back to them would be the obvious suggestion.

Got the same problem here buddy and one of my rims is slightly damaged. About to get it re-rolled in the next week or two; should fix my problem then

tie rod ends

how long has it been happening before balancing? maybe rims wasn't put back on properly. Do you have aftermarket rims? check if the centre hub is the right size, otherwise the rim won't be truely centered, and 5 studs won't be strong enough to keep it centred after driving for some time. it only takes just a few 0.xx mm off the centre to cause vibration. It happened to me when upgrading my stock rims to aftermarket, need to go back to the rim shop to get some centering hubs.

or perhaps the rotors need machining? with my old rotors that fixed the vibration for quite a while (until I swap to 17" rims - then it became the rims' problem).

well if as you say the wheel alignment fixed it then I'd go with the wheel alignment bolt not being tightened up correctly and has come loose after a day returning you to your previous settings. Get it re-aligned at the workshop or at least go back there to tell them the problems back
