You may remember my previous thread in which I started on the intermittent power steering failure in my sisters Grande. Unfortunately my spare time and the weather haven't really lined up so the car has been to a couple of garages. I'm not sure what the first did but they just said that the EPS motor needed replaced and it does not look like they did anything with the ground straps in the engine bay as suggested here on the forum.
To clarify; the issue is that the power steering goes dead when you turn the wheel away from centre however it seems to function normally a few of degree's in either direction and even further if you turn it very slowly.
I sent it to the garage I normally use for a second opinion and specifically asked them to clean up the ground straps and the EPS torque sensor connector. I spoke to them today and they said that the EPS motor had a vibration while turning the wheel. They also mentioned that there was a ring behind the steering wheel that was slack which they have tightened up but I'm not sure what that is.
With this new information about the vibration from the motor, and keeping in mind that it works slightly off centre and when being turned slowly, would the original garages diagnoses of a failed motor be correct?
Is there any other quick fixes I should try before sourcing a EPS motor?
How big a job is it to change the motor?
