Power Steering Issue.

[Ehgriez]

Hey guys.

I've had the strangest issue recently. When I speed up to around 80km/hr I can feel the steering wheel shift to the left and then it stays on an angle until I slow back down where it straightens back up.

I have a feeling that it has something to do with the speed sensitivity of the power steering as it seems to happen at around the point you would expect the steering to be heavier.

Anyone got any ideas on what the issue might be? Only noticed it occurring on Friday.

Cheers,

Greg.

Are you talking about the position of the steering wheel?

If so, sounds to me like it might be a loose steering rack on the mounts. Could be caused by worn standard rubber bushes.

Happy to take a look if you need/want.

Mine used to do that before I removed teh cactus HICAS..

As did mine, My steering Improved alot when Hicas was gone... Pretty sure it was Faulty

Yep this is Hicas playing up...

I have found that whenever I do a wheel alignment or anything where I turn the steering wheel from full lock to lock with the engine off, the Hicas computer goes into some sort of diagnostic mode.

The symptom of this is that the Hicas rack seems free to float or do what it wants. The first thing you notice is you have to correct for this with the steering wheel. Typical the wheel is 10deg of centre on straight road...

The way I fix this particular issue is to stop the car, turn off engine with wheels facing forward. Wait 10-20 secs and then start the car again. All is fine after that.

Now this 'may' be what is happening with your car. OR it could be a fault with Hicas..but definitely something to do with Hicas..

It seems to be more like 30degrees off centre. It is also perfectly straight at low speed, I can FEEL it shift when i speed up.

R Dirty 3 It would be great if you could have a look sometime, I head up to Ellenbrook pretty often anyway.

Have a HICAS lock bar in my boot, should probably get around to installing it.

Brad(RDIRTY3) works for WA Suspensions in ozzie park, so you would be taking it to their workshop

Put the lockbar in and then take it to Brad to be re-aligned, you won't regret it

Mine did this too.

My problem was the result of the HICAS ring location in the boss kit being out of alignment due to the adhesive coming unstuck.

The HICAS thought that the steering wheel was in a turned position and shot the rear wheels out. Twas funny crabwalking down the road at speed.............

Throw out the HICAS. Best move you could make.

+11ty gazillion.

Yeah I need to get around to it, I find it hard to get a spare 6 hours with a mate to get it done is all.

Probably look at doing it next week some time, see if that fixes the issue or not.

ok we ripped that shit out tonight, 3 hours or so of work.

Noone mentioned how f**ked up the bolts are that hold in the hicas actuator thingimy, a good hour of that 3 hours was me grunting and pulling at a huge breaker bar to get a 1/8th turn out of the damn thing-.-

Ah well, got it off in the end. Can anyone clarify which of the boxes under my parcel tray is the hicas one? Is it the one stamped with NISSAN on the passenger side, or the other one on the drivers side?

[bubba]

Leave the HICAS control unit plugged in or you'll lose your speed sensitive steering.

[Ehgriez]

ahhh duly noted. Do I need to do anything else with the wiring?

No. Just pull the HICAS globe in the facia or else it will annoy the crap out of you.

[Ehgriez]

yeah I figured that;)

[Ehgriez]

Just wanted to point out, this has fixed my steering wheel angle issues.

Just need an alignment and all will be fine.

Hi am new in here. Am driving a R34GTT. Well I seem to have this same problem but mine is the steering wheel to drive stairght I need the steering wheel at abt 5 degrees to the right. Even after alignment done they had to manaully drive and adjust the toe to the fronts for the steering wheel to drive staright but after driving a while it well go back to the same?? Done 3 alignments from differeent places the last was at Malaga Suspensions the got the steering wheel centre but still can when ard 100km/h it starts to pull to the right. Can it be what you guys are talking abt tht my HICAS is also f**ked? And how to confirm? Hope you guys can help me out?? Cheers

[Ehgriez]

I'm not too sure how to test it but from all accounts its better out than in anyway.
