Hicas, Big Problem

[tim83mm]

ive had a search around and cant find anyone else with a problem that seems as bad as mine,

thats why im posting,

the 1st problem is under acceleration the rear end feels as if every bolt in the rear cradle is loose and the whole thing is just swaying about to do as it pleases very unseltling feeling,

but whats worse is under hard braking the whole car pulls very savagely to the right, requiring you to make sure yourve got a firm grip on the wheel incredable unselting

now ive checked everything from all the plug and loom conections, pwr steer fluid level/leaks, even the rear rack to make sure it was secure

so im stumped as to what it could be, so if anyone can help, please

(sorry bout the rave)

It could be that your bushes are stuffed giving some slack in the components.

same thing with my R33 Gtst........especially on bumpy sydney roads. Very unsettling indeed, some say the ride is supposed to be this harsh

This is a bush/alignment problem. Get the Pedders safety check done. Cheap and professional. If HICAS is a problem it lights the warning lamp on the dash.

Can I suggest that the brake problem is unrelated to the rear end problem. The brake problem is probably the result of the LH caliper siezing, sometimes it can be an imbalance in the front caster settings.

someone hasn't cut the speed limiter have they?

Its denfinitely not a problem with bushes as it has nolathane bushes fittted through out front an rear,

and i can tell the difference between the the two it is the hicas, badly worn bushes never feel like this

its not an alignment issue either as i just got new tyres fitted and a alignment done,

but the hicas warning light is on most off time to

and the car is fitted with an aftermarket steer wheel to

<{POST_SNAPBACK}>

That would have been useful info to have from the start

Is the wheel a proper HICAS wheel? Is it aligned correctly?

hey there my r34 has the same problem, i thought my shocks wer gorn i have hks coilovers, n i have dat HICAS appering up on my dash. is there ne way 2 fix it o get rid ov it? B)

[tim83mm]

I pulled the steer wheel off and had a look, but im quite sure what to look at,

there was 2 plugs at 11 and 5 o'clock pos, but one just looked like the pwr for the horn

the car has a momo wheel on so im sure wheather its compatable with hicas

[GTRgeoff]

There should be a slot in the back of the wheel for a long black protusion in the centre of the wheel to insert into.

Also what the elk says sounds like a good opinion too.

Did the subframe bushes get done as well??? if not they are the culprit I'm talking about.

There are two different boss kits for R32 (unsure of which model you have). Part numbers ON-110 and ON-115 (iirc) and one is used for early model R32's and one for late models.

Search for a thread titled "My GTR" by "Pentae" and there is a lot of info on the second page. Might help clarify? If not R32, disregard!

hi, did they do the bushes in the hubs also and the rear rack ends/tierods, if these are worn this will add a lot of wiggle to the rear end, jack up rear of car, support on stands and try to turn the rear wheels left to right by hand, there should be no movement at all!

but more likely it will be your steering wheel, aftermarket wheels seem to cause a few probs with hicas as people dont align the pin properly.

DON'T get your wheels aligned at Bob Janes or Tyre Power etc (just a warning!)...Bob funked my HICAS, the light is on when cold and on when I turn left now

Brakes: check the pads...also the distance away from the disc of the front left pad might be greater than the front right....possibly due to being more warn down.

HICAS: meh!, everybody dance now (Baseketball happy dance )

Hmmm i have a momo wheel aswell i dunno what boss hit it have either i thinks its also momo so i dunno if my hicas is stuffing up i never see light on only when i start the car and then it switches off but i am also getting a scraping when i 1st start out driving the car when cold and a lump lump lump like i am running over golf balls but only with right hand rear wheel i check tyre seems good and when i get abit of speed it seems to go away and i dont feel it till i leave my car and start it again after work.

That sounds far to dangerous to waste money on fixing

Just get a HICAS lock bar. I spent forever trying to avoid doing this cause I had perfectly working HICAS, but it started making the car feel a bit unsteady in the wet so I got rid of it.

HICAS Lock Bar, Wheel Alignment and should be sweet

I have this same problem only the lump sound is on the front passenger side. The car still handles wonderfully, just that sound worries me. I'll probably take a look later in the week when I install my brake pads.

yer well i took my tires off had a good check of them not a problem and all the suspension seem sgood np at all.

[jrm]

Doesn't sound like a HICAS problem to me, HYBRID VL - especially if the HICAS light isn't coming/staying on

Go see a wheel/suspension place and get stuff checked out. Could be anything like worn suspension bushes - best to get it checked out.

[HYBRID VL]

Ok try to get the HICAS diagnostics and i couldnt get the diag happening so im thinking that maybe my HICAS light isnt lighting up because my boss kit isnt allowing it to work.
