Power Steering Issue.

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. :(

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.

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

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.

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?

      1992 R32 GT-R Race Car

      By bardabe · Posted

      I'm selling my personal race car. 1992 BNR32 Skyline GT-R About eight years ago the engine developed the dreaded low oil pressure problem. I removed it and found the issue. However shortly after I moved half way across the country, moved my work shop, bought a house, got married, then moved my shop again to it's permanent location for the time being. in turn I do not have the time to race this car as it should be. In turn the engine I built for this car will end up in my street car and this car I hope finds a home with someone who can use it to it's full potential. The roll bar was built by Jason Noren Fabricaiton in Pomona California to SCCA and NASA Specs. The car used to compete in redline time attack and global time attack enthusiast class. It also has a fire suppression system.  The car is with me at my workshop in Kyle Texas, USA. Shipping it is no problem, I can personally deliver the car to the port of either Houston or Los Angeles. Any other port depending on where it is may require transport but we can always work that out.   The chassis itself is rust free, rear quarters and under fenders are free of any rust so it's a very solid foundation for anyone who wishes to move forward with it. As posted and at the asking price of $20,000 USD the car includes all of the following;   All OEM Body panels, front fenders, rear bumpers etc.  OEM Nissan Projector headlamps (Pictured N1 lamps were removed) OEM Nismo Side Skirts / Extensions OEM Rear Spats  Front & Rear Subframes are installed car is full roller Rear Subframe has Cusco Camber Arms, Whiteline HICAS Elimination Front Subframe has Whiteline tension rods and whiteline Sway bars w/ endlinks.  Buddy Club N1 Coilovers All chassis wiring and engine wiring is in tact. Attessa System is fully in tact and was functional before engine removal.  BCNR33 GT-R Brembo Brakes F+R with Endless MX72 Plus Pads, DBA Rotors & Stainless Steel Brake lines Billion Racing Radiator Billion Radiator Hoses Fluidyne Engine Oil Cooler Accusump System (trunk Mounted) 5 Speed Transmission w/ Transfer Case F+R Prop-shafts Rear Differential With rear Axles.  Nismo Gauge Cluster Nismo Clutch + Flywheel   Essentially what is needed to make this car running and driving again is as follows: A working Engine, an ECU, and time to put it together. The price posted is or best offer as I am willing to remove some components to accommodate price to a certain extent. If any serious buyer wants full detailed pictures, videos, or any questions I'll be happy to answer them. I believe this car is priced to move quickly considering it's a rust free and very straight chassis but always open to fair negotiation.  I can be contacted via phone or email. (+19517081648) email is [email protected]
