Hey lads hope you're well! I'm Dave the new guy here, hope to get to know you all better.

Anyway, for now I've got an 06 wrx with a constant vibration at all speeds in neutral and in gear, feels like corrugated roads. no noise at all, no steering or braking problems. Normal handling over bumps, with the vibration on top. No change to the problem whatsoever after doing the suggested suspension (entire struts to coil overs) and tyres (balanced and aligned). No change after moving front wheels to rear either (in case a wheel was buckled), it still bounces like in the video I made (legally) yesterday on the freeway. It seems to have a rhythm, and is speed dependent, not bump dependent. I'm thinking maybe runout or drive shaft. I think it started after flooring it from gravel to road.

I'm interested to know if you lads have had a similar problem or can recommend a repair shop. So far it's been to Subaru, pedders
, Bridgestone, and jax, they're all clueless! (Edit, have used the search here and on nasioc and a few other sites)

Cheers! Dave
