Heavy Steering Shakes While Turning!

[DaGr81]

ok ive done a search and while everyone has problems with shaky steering at 110 +, i dont have that until i get to 120 (not that i should be doing this hence why i havent fixed it) but my steering shakes violently while turning, softly between 60-70 (theres a sound like something rattling loudly coming from the drivers side, then violently between 70 - 110, now it only happens when im turning to the left (highways) but going towards the right its smooth as silk.

anyone care to point me in the wrong direction so some workshop doesnt spend my savings by guessing whats wrong?

thanks all

Just get Pedders to do one of their cheap suspension inspections, and wahatever they find just replace yourself.

yup thats on the list mate,

more suggestions please if we can narrow it down between now and when i get there that way it would save some time.

Do you still have HICAS?

[DaGr81]

Yes still have hicas, should I block it out?

Hey mate,

That sounds like your driver's side front tyre may have flat spot. If you have a flat spot on one side when you turn you usually notice it way more, also gets worse with speed. Its one thing you should rule out anyhow, so have a very good look at the tyre. Flat spot will usually be towards the inside due to neg camber.

I wouldn't lockbar it down and block the lines till I was sure it was HICAS at fault. Usually the HICAS light would light up if there was an issue (then you would run the HICAS self-diagnostic). Put the ECU into self-diagnosis mode and check for error codes.

Also check your powersteering fluid level (since R32's HICAS runs off it, R33's and nweer are electric-based not hydralic-based)

Cheers for that, I'll check for a flat spot when I get home tonight, hicas light doesn't come on + I've got PFC can I still run a hicas diagnostic through that?

[DaGr81]

I've got a r33 but power steering fluid is perfect as well, but how can I explain the rattling sound and this only happens on left turns as well, but even at 50/60/70 it's loud enough to hear through the exhaust noise

Ok just for future reference to anyone that has the same symptoms, the problem was actually a drivers side tie rod end, problem fixed by installing a rose jointed item (although a pedders one would have been ok) I figured the rose jointed items would last longer. I also replaced both the front ones to prevent future problems. Cost came to $149 for both not including installation which will be done within the next week.

Apparently it can also help with bump steering so i'll see how it goes!

Thanks for all the input though.
