Hicas - Wheel Alginment?

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 :worship:

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

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
