It seems to be a common problem though.Iirc there have been quite a few mentions of steering wheel not pointing straight ahead on here after a visit to WIM ?

its a common problem in all geometry shops.. one man need to climb and hold the steering or use a fixing apparatus which they generally forgot..

I can assure you that WIM always use clamps for the wheel.

Other factors are involved which can and do affect things - although the front wheels are on linear slide plates, there will be some friction.  And the amount of force going into seized track rods....


I always WD40 (on several days leading up to) and plusgas (day before) mine, maybe this is why rarely suffers off centre wheel - well,, until its first launch, anyway

I have been watching this thread with obvious interest wondering when to intervene..... The steering position is the only human intervention the Hunter machine cannot police since it's only interest is the chassis not the cosmetic position of the steering wheel.

Nevertheless us driver are interested in the steering wheel position ( rightly so ) so what's going wrong? The steering box and satellite components have what can be a lot of collective play. No one part would be worn out, just worn, which is the realm most of our cars live in for most of their life. Once the chassis is set the steering position needs to be established in the center of the play and it's here it can go wrong.

Many times i ask the owner to confirm the steering position and still in a driven state the position can be off. It's not good for the owner, me or the ramp time to have a complaint and i strive to get the steering position finalized first time but the nature of the best sometimes defeats me. In an ideal world there wouldn't be any play in the steering box or satellite components but it's not an ideal world. All i can say to those who have made deliberate attempts to use us is i'm sorry if you have been let down, it's not due to poor workmanship or a flippant attitude toward the calibration.

WIM - I know we have privately discussed this, but would it be beneficial to have engine running when doing front toe, to remove some steering box play?

Worth experimenting with, at least?

[tunnie]

Feel free to use me as test, within next month or so I'll be down in the 2.2 for a tune up

Already tried this on my car during the second and third attempts. 2nd attempt was unsuccessful but 3rd time lucky.

Also Tony mentioned the car electronics causes the readings to fluctuate. Probably not enough for the readings to be incorrect though

[TheBoy]

Guess where TBE is right now?

Getting those shit tyres replaced? 

[SMD]

They can't be that bad, that they warrant replacing after a couple of months. Surely they are good enough for TheGirl, unless her name is Susie Wolff

Replacement is being seriously considered, they are THAT bad

But not this weekend.

Re engine running, we tried that several times.

On my old car, talking purely about the cosmetic centred steering wheel, and not pulling oddness, the deciding factor was sorting the rear track rod adjustment, as the rear was being steered out of line from the rest of the car. A slight crab, in effect.

Heat those bloody rear track rods.

[TheBoy]

I've always left with thrust angle at 0 or 0'01, possibly why I never seem to have trouble with offcentre steering.

There are benefits to a daily dose of WD40 in the week leading up to calibration

That said, TBE needed an awful lot of heat yesterday. I thought we were beaten....

[LFF64]

I wouldnt mind a slightly off steering wheel as long as the car went in a straight line 

[LFF64]

And I must add Tony has been really helpful in trying to get mine sorted 

[SMD]

still not sorted?

[LFF64]

No  I
had it adjusted earlier today while they had it in doing the tyre (not WIM)(simply tyres Aylesbury)
It seems better and doesn't drift as much but still does slightly they said they put it back to VX settings they have they did have two goes at it they checked it this morning aftervI said it was worse than before and it had moved so not sure what's going on there I will keep an eye on it and watch out for tyre wear
