Rear Wheels Swaying From Side To Side? Help Pls

[PSI.33]

Hey Everyone,

Just a quick question regarding my handling as its gettin me a little concerned.

Has anyone had this issue with their r33 as well or have any ideas what this could be?

When im driving it feels as if the rear of the car is swaying from side to side.

Appreciate any feedback guys

Regards

Michael

Check your rear cradle mounts and bushes

[Spunky Munky]

I suggest you check your tyres...are they too worn? I just to get heaps of rear wheel fishtails when I had worn out tyres...spend the extra cash on your tyres for safety...

[Gabbo2047]

had the same problem. turned out to be rear tyres were worn on the inside. changed and problem went away. went and got alignment and camber adjustments done the next day.

[Kinks]

I only get that problem when I'm trying to push the throttle through the firewall, I'm in 2nd gear, and it's wet.

Besides that nah haven't noticed it. Make sure your HICAS is plugged in and functional.

Try turning off HICAS all together, pull the fuse and the plugs(under car). I had this stupid prob where my HICAS was not functioning properly and felt like i was oversteering when taking corners slow on wet days(which i found out later it was acutally the HICAS doing some extra turning for me). Sometimes even "swaying" while driving straight on a wet day(whn driving alittle harder thn ususal). See if that works for ya

I'd bet $100 on HICAS... had this exact same problem on my GTR, locked out HICAS and all was well with the world.

yeah there could be a number of things. drop by pedders for one of their 14$ checks and see what they tell you. I'm sure they won't miss anything that is worn and needs replacement

[_bobo_]

yeah it happens to me to, only in the wet and when its raining,

ill be driving along at around 70-80k's and feel the car sway side to side, feels like its loosing traction a bit, and at that speed unexpectedly; its a bit scary lol, especially when you notice all cars behind you move away and overtake =].

I think it is the tyres though, although mine are less than a year old and are pretty much bald...and for this set of tyres i havent been doing anything stupid like burnouts or anything, only thing that would of demolished them would have been doing the advance driving course.

my money is on bushes.

The arse end was moving around on mine a fair bit.

It was two things.

1. Left hand rear hicas tie rod ball joint was shagged causing the rear to tramline when cruising and at WOT.

2. Subframe bushes were shagged (leaking) causing the car to feel as if it was steering from the rear under hard throttle only. On the dyno I could see the subframe pushing forward.

I locked out the hicas and removed the hicas lines to the rear of the car, if you have an R32 gtst be sure you fit a power steer cooler if you remove the hicas lines as you'll find the steering will become a little stiff as the temps increase on hot days and when giving the car a hard time.

The exact same thing is happening to me.

I am getting and have been getting it for awhile, noticeable lateral movement over the rear tyres, only on certain uneven surfaces.

I have read on these forums of that being a hicas issue. BUT this is server swaying and only happens occasionally.

Took it to pedders, they were nice enough to hold onto my car for an hour or two, do a few 'blockies' and proceed to tell me it's all good. (Didn't surprise me when he didn't ask to be paid)

Also on a side note my rear right is toeing in with a few degrees of negative camber(can take a photo) and I am only seeming to spin the rear left wheel now too.

So it's off to a new suspension shop and try to get someone with an idea to fix my car then the diff than the......

try shock absorbers rear are they doing a dance kind of when you go over a bumpy surface thats what my problem was

+1 for HICAS issue.

I'm driving a WGNC34 and experienced same symptom. All the sudden the car's rear end becomes wobbly, it feels quite nasty especially at speed of 100km/h+.

Mine had some HICAS issues back in last winter, the dash light lit and steering became somewhat odd, hard to describe. Back then I found that the main position sensor of HICAS did have marks of damage (it's basically the lowest part of the car near the diff and can be easily damaged when driving on rough surfaces, gravel or icy snow). The main angle sensor (the one right next to HICAS motor) was cracked on the base of connector and I fixed it then and all went well for a long time but... Well, today the same problem occurred and this time it was very unpleasant. Rear wheels from left to right on random intervals and on every driving speed, usually HICAS comes on when driving something like 60km/h+ but now freaked out all the time car is moving.

As I have to drive daily I didn't have time to start checking sensors or the motor, I just disconnected the motor connector and left the whole HICAS off for now. I must continue with the fault diagnosis whenever I have the time. Luckily I have another working ECR33 HICAS to change sensors if needed.

And for the record, I have fair shocks, brand new tyres and steering angles adjusted not long time ago.

If anyone has ideas of how to continue with the inspection I would be happy to hear.
