it just be air screw adj ?
HElp Thanks john.
It's worth getting the suspension set up by a specialist.
Hi
My book locost failed on this. I got the tracking set up properly and it passed, but still didn't centre in the way I wanted.
I welded wide upper wishbone brackets on to give more castor adjustment and replaced the sierra steering column bearing with a spherical bearing which
made a small improvement. The thing that made the most difference was adding a shim in the steering rack box to free it up.
If I was doing it again I would try the tracking set up and extra shim first before getting the welder out.
Good luck
Dave
The quick trick for IVA ( you should do it properly in slow time) is to pump up tyres to 30+ psi and put some toe out to the setup
This is only a temporary fix
Well known cock-up in the book that the 7deg of castor was only 3.5deg. Ive made mine with the full 7 and should be fine but it doesnt center like a production car.

Other bodge is valve springs inside the steering rack boots limits the steering though when they get coil bound but does the trick.
Not enough caster have it checked
