Hicas - Wheel Alginment?

[Greg]

Well I refitted hicas today, the aim being to get back my power steering, which it did but not as much as i hoped (power steering pump probably on its way out).

Anyway I have a handling problem now. It feels like the hicas rack has a lot of freeplay in it, sich that with any front steering movement, the rear wheels are free to swing the full movement that the rack allows (regardless of what speed I'm going). I can feel the rear end swaying side to side (like an S going up the road). The hicas light is not on and does not come on when this is happening.

I did a hicas diagnostic and got code 32 (neutral input switch not present). I always got this code and previously there were no problems.

The wheel alignment looks to be straight, but I'm going to measure when my I have another set of hands to help me.

Any suggestions would be appreciated.

my suggestion would be to re-lock out your hicas and get your power steering problem sorted

air in the system?

wow that was quick! thanks for your replies guys

I did a dodgy wheel alignment with a tape measure, it previously had ~1cm toe out EACH SIDE! I set it to ~neutral and the problem is gone!

Amazing how much difference the toe makes.

absolutely toe in/out changes the way the car feels dramatically
