Default Re: Slight vibration after subframe reinforcement

The fact that it only does it from cold and only for a few minutes and then goes away tells me it's not related to bushings/engine or tranny mounts/guibo/csb.

Does the car only do this when driving from cold, or also while simply idling for say 2-5 minutes?

Sounds that once it warms up there is some clearance change and enough pressure/volume of some fluid circulating...

Have you tried letting it start from cold and simply turn steering wheel lock to lock? Revving it a little do anything with car stationary?

I had steering wheel vibration at slow speed when my power steering reservoir was low because one of the banjos was a bit loose and there was a leak. Driving a higher engine speed seemed to smooth it out with pump circulating all the fluid.

Would be helpful to really isolate where this vibration is coming from, like at least front or back of the car.
