Car pulling to right under load.
Hi,
I’m looking at buying a car (Volvo!) which tracks very slightly to the right when coasting, although when accelerating is reasonable. I cant say I remember the steering wheel moving although it did seem to want to pull very very slightly to the right when driving in a straight line. Its just had 3 new tyres (rears and drivers front - 235/40/18) and a new drivers front shock absorber - by a Volvo main dealer. I don’t think its been tracked. I appreciate it could be a number of things, although does anyone have any starters please? Its going back to Volvo for them to have a look, but talking to them on the phone they didnt see too sure. Many thanks

Oh, its 3 years old and done 60k.
Shock was replaced due to leak. I assume the other front would be best replaced to keep them paired?

How does it react under braking?
As you say, i'd first start off by getting two tyres the same type and wear on the front and then see how it feels. It could be a difference between the shocks and likewise I personally think it's best to replace those in pairs as well. I assume it was just an OEM replacement shock? It could be just an alignment issue, especially if something has been disturbed during the shock replacement. However be cautious if you're thinking about purchasing because if it's not suspension related, it could be chassis related

Hi Martin,
Braking is fine, albeit I didn’t lock up as I had the family in the car as well, but if it was the shock I assume it would show something up under reasonable braking? Being low profiles (more so than the Supe!) are the tyres more susceptible to any minor geometry deviation? The old tyre I’d say has 4mm on it. HPi'd fine and spoke to the main Volvo dealer who has always serviced the car and all was good. (This was whilst I was inspecting the car on loud speaker) Seems very genuine, but you’ve got to trust no one. They seemed just as surprised, as they just MOT’d it hence the OEM shock. It has active suspension (soft/hard setting) assuming that’s all working fine. No fault lights.

Yep, would expect if it was a dodgy shock that it would show up under braking, especially after lifting off.
Lower profiles certainly do make geometry problems more pronounced, because there is less sidewall to absorb any movements. Think i'd try to organise the same tyres on the front and if the issue is still there then get to a geometry specialist with it. May seem a little extreme for a daily driver but they would tell you more in an hour than us lot hypothesising. Also the money spent you'd probably recover on reduced tyre wear over the years

Had it looked at Volvo and couldnt find a problem, which was what i was expecting.
They swaped the tyres around and it now pulls slightly to the left!!

LOL
Did they swap front to back? (assuming the fronts are directional) Actually thinking about that, if you have directional tyres are they all on the correct way round?
