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

      @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.

      I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.

      Duncan's V37.......race car?

      Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.

      Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
