Wierd Steering Issue

[dmr]

my friend owns an r32 gts-t, stock springs, shocks, rims/tyres, steering wheel etc.

he showed me today a puzzling problem how the steering is normal up till about 65-70km's, which then the steering wheel automatically turns to the left roughly 15 degrees while the car stays straight and remains there.

if you slow down under the 65-70km mark, the steering wheel then turns back to 0 degrees while still staying straight. pretty tripped out!

he's had no smashes or anything like that.. does anyone have any idea what would be causing this?

I have a feeling this could be something to do with the hicas. Hicas kicks in at ~80kmh mark.

What's happening to your friends car is wierd though, never heard/read of it before.

that's what i thought too, but he has no hicas issues. he had a hicas issue when his speedo cable wasn't working inwhich it wasn't sending a speed signal to hicas, causing the steering to go hard. but that was fixed a while ago..

[dmr]

anyone else have any idea what would be causing this?

[scarface]

that happened to me too, u got air bubbles in your power steering, i bled my power steering and it went away

[dmr]

thanks buddy, i'll help him do it tonight and see how it goes

sounds like the hicas is turning one way and so he is automatically correcting.

remember that the steering wheel has a connection to the rack, so if the steering wheel turns you are turning the front wheels, the steering wheel just can't turn on it's own without turning the wheels.

problem. the hicas controller is stuffed. solution. replace the controller or get a lock bar.

it happened to me but it was a bit random and generally when accelerating hard, so i locked the rear rack.

My car used to do something similar, the wheel always sat about 10deg left of centre and at about 80km/h when accelerating hard, the back end would get a bit quiggly for a couple of seconds - only around 80km/h.

Removed the rear steering rack yesterday and whacked in a lockbar (cheers NV_01), steering wheel now sits straight and no more squirling in the back end..

I can only assume I've been crabbing along for a while now O_o another thing I noticed was that when reversing out of my driveway the wheel would sit about 10deg to the RIGHT, then left again when moving forward. I think hicas was fubar'd!

its a problem with the hicas, install a lock bar it could possibly solve the problem

THANKS FOR THIS INFO GUYS!!! I thought I was just going crazy with my R32 because on the freeway the steering wheel would sit to right but when I was driving in normal streets (60k zones) the steering wheel would be straight. Might have to convince the g.f to let me get a lockbar and see if that fixes it.

i had this problem...was quite nerve racking when it suddenly does it.

mine went away...but i am removing my hicas atm...how much of a pain in the shitter is it!!!!!

Why did nissan even put these hicas systems in in the first place. Everyone takes the bloody thing out.

Yeah i had similar problem on GTR locked the hicas and never done it since, very unsettling, and weird when you tell people and they say no that can't happen, Yeah well we know different, It can and it does.
