A4 1.8 fwd
I have read so much my head is spinning and my pocket is empty from replacing pretty much everything suspension/drivetrain related

I have a rotational throbbing In the steering mainly when turning right, left slightly.
The faster and the more I turn, the worse it gets.

I have replaced all control arms, drop links, front wheel bearings, tie rod ends, outer right CV twice and the right CV shaft once. Steering rack and pinion.
Put brand new coilovers in, but I still get the problem.

I have removed the coilovers several times to check torque.
Double checked all control arm torque, but no luck.

I put it down to CV again.... But its only throbbing like theres a bubble in my tyre, no sound on full lock (no nasty clacking sound)

Could it be drop links? I hear if your cars low, standard drop links can cause issues. Is there a way to eliminate them as a problem?

I also have a power steering leak somewhere near the firewall, my guess is the bango bolt or the high pressure feed. But i don't think it Is related as the pump is fine.

I have replaced too much, just need some friendly advice.
Cheers to all.

 

check your wheel bearings.
