steering self centering
Hi all
Advice please.
When checking for self centering I found that when turning right centered ok, but when turning left did not.
Comments please.
Cheers
Keith

Did you make sure the top wishbones are the correct way round?

Caster is normally the biggest factor affecting self centering - also toe in and tyre pressures.
As above, check that your wishbones are the right way round, making the top ball joint behind the lower one. You might try a little less toe in and
increasing tyre pressures

And check that your steering rack is centered when the wheels are pointing straight ahead (may account for the assymetric centering).
To check - wind the wheel fully left, then go fully right while counting the number of turns of the steering wheel. Divide the number of turns by 2,
then wind the wheel that many turns back towards the left. If your wheels are still point straight ahead then you're properly centered! If
not, leave the steering wheel in that position and adjust the track rod ends until they are. You'll need to re-adjust the tracking afterwards
if you do this.
(and apologies if you know all this already).

Very recently Gavinc had the same problem at IVA, we did the same thing rotating the mushrooms to add more caster andtoed the wheels in, this was
better but no cigar, the tester hinted that on some occations toing out had helped, we did this and bingo we passed.

rotating the mushrooms doesn't alter the castor as it's measured by the angle between the ball joint centres not the angle at which the
hub lies back.
That's prob why it didn't work, not being pedantic just saying so it will save others doing it needlessly
