Gday to all you R32 guys...

I have an R32 GTST and after say 10mins of highway driving at say 70km/h+ my car feels as if it loses its rear grip for a half and instant - scary stuff. My HICAS light then comes on.

I have deduced with the help of my new mechanic that it is the HICAS system changing the steering direction of the rear wheels. When you first start up the car apparently the rear wheels steer in the opposite direction to the front but after several minutes of driving they revert to the same direction as the fronts / / to / /

/ /

if you know what i mean...

My question is... does your R32 suffer this herendous and sh#t scary tail wag as it changes??? When i say scary i mean drift style sideways (so it seems)...

Your feedback is much appreciated...

Mine's fine, never had any probs with it in the last 14 months. My hicas light used to come on but it was caused by a leak in the power steering pump. The light is only a warning to tell u if its not working. The hicas only moves the rear wheels something like 1.5deg either way depending on speed. Hope this helps :D

Mine does the same thing. I have almost taken out cars when you get caught in rydges in the road. Bloody scary.

My hicas light is on and my steering has gone heavy. I think it might be the power steering solenoid down near the rack.

Let me know if you sought it out.

Cheers guys...

yeah Doc, that's it - it goes really heavy and sometimes my car actually stalls if it occurs at slow speed.

I remember now that my mechanic said it had something to do with the aftermarket steering wheel i have because the sensor is apparently linked at the steering wheel and when they fit an aftermarket jobby it screws up the system somehow.....

Haven't had any problems with my HICAS on the hwy. Did save me from a great mess once though when I saw a turnoff too late and hooked it hard left at (undisclosed)km/h.... Instead of sliding off the road and into that big tree...I was carried merrily on my way & into the corner - felt bloddy wierd!

When I first start the car, I have to turn a left & right a little before the steering becomes light again.

Also If I idle the car for too long the HICAS light comes on. I've tried running the diagnostic, but it wouldn't work :confused:

MY R32 gtst won't show the hicas light at all. Full stop. There is no light from what I've seen. It seems to turn o.k, but i've NFI if the 4ws is actually working or not. The computer is still plugged in under the rear parcel shelf, the rack is still there, all of the hydraulic lines are still there... I dunno?

mine isnt really disabled properly it just doesnt work lol

im waiting for Dr-Drift to come over with my pineapples so i can pull the plug on the hicas and disable it properlly... but if u ask me... its a hell of a lot better... i hate how it pulls to certain sides when driving before it stops working... even before i stuffed it i hated the feeling it gave when turning.

Had the same problem and took it to givin wood on the gold coast.

The problem was the steering selector for the hicas.

It seems that there are two types and on one the selector is at 38 degrees so that at speed the thinks it is in a permanent left turn. this problem is only fixed with the correct part or by a hicas lock kit.

I've never had any issues..

Just a question for all those who are saying that they have a hard to turn steering... have you checked the power steering fluid recently?

Have you changed it at all?

As for the drift pineapples... they do not do anything for the HICAS. I believe that they are simply for stopping axle tramp, and allowing you to set your car to drift a bit more stable.

The only way to disable HICAS on our R32's is to get a proper lock kit.

You can't just disconnect the computer cause that means that the rear is then able to turn 1.5 degrees in any direction the road drags it.. NOW THAT would be scary.

When your HICAS is working properly, it only works when you are traveling above 80kms. And it ONLY works to turn the rear wheels in the SAME direction as the front to make lane changing on the highways, a smoother process.

So this thing about your mechanic telling you that it turns opposite at low speeds and same at high speeds is false.

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
