[BP5 Legacy 2.0GT Steering vibration issue]

All is well now, it seems that one of the wheels wasn't quite sitting right when I bolted it up to the hub.. it looked fine and the wheel lug nuts were tight, but meh, its ok now and I don't have to worry

 

[BP5 Legacy 2.0GT Steering vibration issue]

My partners 2007 Legacy GT seems to have an issue with the steering, or perhaps the drive train, when turning at low speeds there is quite a vibration through the steering, which seems more evident at certain steering angles, or often just steering the steering wheel left and right a little when not moving (as a test). It seems worse when the car is in Drive, in Park its not as bad.

 

Perhaps the idle is too low? I have noticed the idle drop a bit when experiencing issues, but it has never stalled.

 

I have replaced the Power Steering Fluid, this helped a noise issue the pump had at least.

New Front disc rotors (nothing to do with this fault) but they were warped and needing doing.

This car was complianced 5 months ago and it has done 5000k's in that time, the suspension bushes etc look fine, could a wheel bearing cause this issue?

 

I noticed a little bit of oil around the flange on the small intercooler pipe that goes from intercooler to turbo. 

I removed this and cleaned it up, the o-ring still looked fine, was a tiny leak.. but will monitor..

 

This problem has really only occurred in the last week or so, previously the steering had been fine.
