Gtr Sorta Just Swerves Itself

[Evasion]

Hi guys just picked up my 32 gtr last night (farking love it awsome awsome car and thats coming from a 3037 equipped 180sx owner lol) and was just curious into something that has happened a few times.

I was on the highway from picking the car up travelling arpound 110-120 on slight throttle to miantain speed wasn't really full concentrating so don't know any thing else, but all of a sudden the rear end of the car sorta stepped/steered out to the left and I had to correct the steering, it felt as if the rear wheels were turning as in 4 wheel steering.

Another time I accelerated hard 1st 2nd 3rd for a little bit taking off onto a highway and when I backed off the throttle the car again sorta stepped to the left again,

My car is suppose to be fitted with a tomei hicas lock, when I turn the car on the hicas light comes on and never goes away so I presume its cause its been locked.

Is this normal possibly to do with power been distrubited to opposite wheels atesa? etc or something, its just got me worried as it is pretty scary when your car does something you dont expect.

Also while driving theres no wobble or weird steering feel but the car does slightly pull to left not bad though.

could be a number of things ie worn bushes etc - the rear cradle ones can fail although the car shouldn't behave radically. try checking wheel alignment first and see what you have. GTRs havea tendency to tramline but that's usually felt at the front.

it is not normal, definately get the rear end checked out

check that the lock kit it fitted right also!!

Check the rear cradle welds near where the control arms attatch to it, they can crack and eventually break off VERY dangerous. I wouldn't be going anywhere near 100klm/ph until you have it checked out.

Sorry to hijack.

When its said that GTR's (r32) tend to Tramline.

How is that problem fixed? is it because of the AWD?

Thanks

if the tomei lock kit has been fitted correctly it shouldn't light up the hicas light.

I suspect someone has just unplugged the solenoid in the engine bay and the rear end is flapping in the breeze, or the warning light is really telling you that there is a problem.

I had the same thing happen in my 32gtst and it was a problem with the hicas. First port of call will be to check that the rear end is locked as it doesn't sound like it.

sounds like tramlining. if it does it heaps over a specific stretch of road drive back over it and it would probably do it every time... common with wide rubber.

Hmm K, thanks for that cause the hicas light never turns off so may be telling me something there, have to visit a workshop sometime soon and pop it on a hoist and get someone to look over it.

Its just weird its done it prob 5 times now, did it again and I have noticed it after I give it a squirt so dont belive the road surface is the problem.

First check that your power steering fluid is up to the right level. If its low the HICAS light will come on. Mine was right at the bottom of the filler reservoir - bringing it up to half way (check the markings on the stalk connected to the cap) sorted it out.

Well first things first:

Have you had a chance to get the car wheel aligned? One of the side effects of getting a HICAS lock kit installed is that is puts the rear toe in out to the shithouse. Too much rear toe will cause you large amounts of rear wheel tramlining. So check that first. Will cost you <$100 and is worth doing on a newly acquired GT-R in any case.

Secondly have a look under the back for dead subframe bushes.

I feel like an idiot, yesterday I was going through the engine bay comparing where stuff is opposed to my 180 and I completely over missed the power steering resovoir, had a look at that just then and no oil was in it so topped that up and that got rid of the hicas light. And it is not a major swerve as the title suggests more just just like it strafes to left for half a second just to give you a quick shock. But yeh has only happened a few times last 2 times been off throttle after accelerating hard, if it happens again ill be going for a wheel allingment/get it put on a hoist by mechanic

No the AWD has nothing to do with it. Symptom of wide rubber and suspension geometry, can be exacerbated by using stiff sidewal tyres - I had Michelin Pilots for a while and they were hopeless for tramlining. Yokos hardly cause a problem.
