charlie_pank Posted May 26, 2016 Share Posted May 26, 2016 Things we have done so far (still pulling to the left, just the same):replaced (bent) subframe and lower wishbone - we suspect they were bent when I popped a tyre in a pothole a little while agochecked alignmentcorrected casterSwapped wheels around front --> back Things we are going to try:jack up both sides at front and run engine to check for faulty power steeringjack up and spin wheels to check for bearing failure or brake dragAny other suggestions?

colindavies56 Posted May 26, 2016 Share Posted May 26, 2016 don't swap front to back,swap left to right. Link to comment Share on other sites More sharing options...

CharlesElliott Posted May 27, 2016 Share Posted May 27, 2016 Pulling is often rear toe. Did you check the rear alignment?where are you? I would suggest taking it to a specialist alignment place like Wheels In Motion. Link to comment Share on other sites More sharing options...
Q Catcher Posted May 27, 2016 Share Posted May 27, 2016 It was brake drag on one of our tintops a few years ago: left disc hotter than right; replaced caliper, job done. The difference in disc temperatures was very noticeable, so if one's not hotter than the other, it's probably not that. Good luck. Link to comment Share on other sites More sharing options...
charlie_pank Posted May 27, 2016 Author Share Posted May 27, 2016 the plot thickens: the steering wheel gets turned 90 degrees to the left when going forwards just a few yards and about the same to the right when going backwards. I think therefore it can't be the power-steering. This behaviour is consistent with either the front left bearing or brake dragging. Any other ideas?

7 wonders of the world Posted May 27, 2016 Share Posted May 27, 2016 you say castor was corrected was this set to OE data as most cars have unequal castor left to righ to counteract the crowning on the roads, ie they are set with a rightward bias add this to the crown and you get a neutral pull.If they have been set equal this may be your source.

charlie_pank Posted May 27, 2016 Author Share Posted May 27, 2016 I don't know if it was set to OE data, but it pulls significantly regardless of camber, so I don't think this is the source of the problem. Link to comment Share on other sites More sharing options...
MADMALC Posted May 27, 2016 Share Posted May 27, 2016 'the steering wheel gets turned 90 degrees to the left when going forwards just a few yards and about the same to the right when going backwards'This sounds like a broken/lose/bent track control arm. There may also be a problem in the rack that you can not see where something is again broken/lose/bent. Link to comment Share on other sites More sharing options...
charlie_pank Posted May 27, 2016 Author Share Posted May 27, 2016 Do you mean the steering arm? I thought the track control arm refers to the lower chassis -> upgright link. In the case of my car it's wishbones top and bottom. The lower wishbone was replaced along with the subframe.It could be the steering arm, or something in the rack. It would be likely to introduce some play in the steering though, would it not? Link to comment Share on other sites More sharing options...
SM25T Posted May 27, 2016 Share Posted May 27, 2016 No play if something bent. Maybe the pothole also impacted on the rear suspension .... a few mm out at the rear would affect the steering greatly. Link to comment Share on other sites More sharing options...
MADMALC Posted May 30, 2016 Share Posted May 30, 2016 Hi C,If there is no drag on the wheel rotation to cause the steering to turn so quickly then my, admittedly, limited common sense says something is broken/lose. When you go forward the steering angle is changed one way and when you go back the natural forces exerted on the steering send it back. Can you get under the car while someone pushes the car back and forward with you holding and feeling each joint in the steering and suspension in turn?love m Link to comment Share on other sites More sharing options...
MADMALC Posted May 30, 2016 Share Posted May 30, 2016 Me again. Another thought. If the 'king pin' or macpherson strut is bent then as it rotates between the top swivel point and the bottom swivel point the hub would not rotate evenly about the axis and thus cause uneven/different steering compared to the other side.Sorry if not explaining very well, blatmail me if you need more.l m Link to comment Share on other sites More sharing options...
