Vivaro pulls to the right when accelerating

[alchim]

Vivaro pulls to the right when accelerating but steering wheel is straight,brand new wish bones fitted,there’s no play in track rods or ball joints, tyres are new, and tracking has been checked,any ideas anyone.?.

Tyre pressures correct?

Get a geometry check, especially as you’ve had suspension arms changed.

Torque steer

I drive a 65 plate, the facelifted version and it does seem to wander a bit above 40mph on sort of less than perfect A and B roads and does pull right noticably under power. No knocks but a dry creak from the OSR over speed bumps etc so I was leaning towards strut top mount but could be wishbone arms or as has been said, geometry needs a tweak. On the latter, a routine check and adjust is no bad thing regardless... assuming there's no worn / bent components, which should obviously be rectified first.

Binding brake?

[GreenV8S]

All the possible causes for that are scary. I would be very cautious about driving it until the problem was found.

I had this problem and noticed it more when i put it in reverse, turned out to be a rear lower axel bush somehow the nut and bolt had worked lose and the arm had elongated.
My local garage welded it up and replaced the bush good as new now

As above, that is not something simple like a binding brake or torque steer, it is something vital/critical & potentially extremely dangerous.

I personally would NOT drive the car at all until it has been jacked up & every suspension joint checked.

1st port of call would be checking what has just been done has been done right.

Why did the wishbones get changed?

Changed your tyres recently?

[ingenieur]

It's a van, who cares. Get on with it.

It sounds like that. I didn’t think many vehicles still exhibited this nowadays.

Might be worth knowing what in the rear controls toe in and toe out.

In my car for example there is a rear trailing arm which controls toe. If the bushes holding rear trailing arm are worn then you can get all sorts of weird behaviour like that.

Sometimes with these things it can be illuminating getting someone else to drive the vehicle for you over various types of roads in a manner likely to display the symptoms, whilst you are in another vehicle and watch how the vehicle behaves.
