Vibration Front End? Z3 1.9

[S555RGC]

Hi guys...got a weird one.

There is a vibration at the front end on my z3....I think it's more passengers side.

It only happens at 2700 ish revs and is more noticeable when coming down the revs and not on the throttle.

The vibration can be felt through the floor and through the gearstick if you put your hand on it.

Once you pass 2700 up or down the revs there is nothing.

Any offers of what this may be...I have my theories but would like to hear your thoughts please

Regards

Rhys

Hi Rhys,

Take the front N/side wheel off and inspect the bushes. You will most likely find that they are perished and need replacing. If you don't, it may be something worse like a bent control arm which you would need someone who knows what they are looking for to diagnose. Most of the time it's bushes.

If you only get these vibrations at a certain RPM/Speed I doubt it's wheel/hub related as the logic doesn't match up.

Keep us posted,

Daz

Car thoroughly checked over....no issues found

Maybe a bit of heat shield on the exhaust?

Did a track day in it on the weekend with no issues at all so all must be well.

Exhaust is being changed soon anyway so this may dispel or confirm the heat shield theory?

New Longlife cat through to tip exhaust installed and the vibration has gone, must have been a dodgy mount or lose bracket/heashield
