Bad Vibration

Post by punk_180 »

Hey all,

as some may know i have just bought a 75 series 1HZ 1992 model.

I was driving today and i noticed that on the way to my destination at over 80 km/h there was a vibration that was coming through the car and was quite noisy and rough.

Well on the way home it was doing it but it was getting worse. It is now doing it for around 50km/h up. It seems to be doing it both under load and not under load. It isnt as bad on the throttle and when you get off the throttle its really bad.

I have just had a wheel alignment done on Friday.
The mods i have are:
2" OME suspension lift
Brand new 33 x 12.5" cooper STT's with new rims.

I have spoken with my GF's brother ad he said his does something similar but not as bad and he seems to think it may be something in the diff.

Can someone please shed some light on the situation please.

Thanks all.

Check all bolts, wheelnuts first. Could possibly your uni joints but. Check the angle they are on. I'd say your rear uni's are now on a big angle due to the 2 inch lift. I know 2 inches aint huge, but it was enough to knock mine over the edge and start shuddering.

Good luck bro.
