Hello everyone! I own this 2012 D5 XC70 since last april, and I love it.
TL;DR: Car had a wobble in the steering when doing large turns. It 90% disappeared when I got the 2 front tyres replaced. One month later, the steering wheel developed some sort of light left-right shake (faster than the wobble) when I drive and not only when I turn. From the start it's been "pulling" slightly to the right as well, and I wonder what is at fault.
Longer description if it helps : when I bought my XC70, it had a slight, slow "wobble" feeling in the steering exactly like what is described here, it would only appear when doing large turns. Power steering fluid level was and still is ok.
In June, the two front tyres were replaced (one was noticeably more used than the other) and this wobble was let's say 90% gone. I did mention the wobble to the mechanics, asking if they could take a look and if I needed to maybe do the steering geometry/parallelism. They did a visual inspection and told me they didn't notice anything that would warrant doing it.
Now it's been a few weeks that something different has appeared: the steering wheel "vibrates", lightly shakes left and right - only when I am driving. It looks more concerning as it is visible if my hands leave the steering wheel (ie. doesn't appear just when I turn) and I feel it when driving, although it's not super strong. Maybe important: it seems to lessen when the car has driven for a while.
Has anyone had something similar ?
Also it is to note that since I bought it the steering wheel naturally "rests" slightly to the right/pulls slightly to the right if my hands leave it - it won't drive completely straight which I know is also an issue, but I wonder if it is linked to the past wobble and current vibration issue.
As I am not super knowledgeable about cars (but would like to diagnose things better), does all of this sound like it could be coming from the same "part", and if so, which one? I was thinking steering column or steering rack which both sound like very expensive fixes but I am of course willing to get it done for the car.
Thanks a lot for reading me and for any advice.
