zoomzoom Posted May 17, 2008 Share Posted May 17, 2008 ok, i searched for some other threads though i thought id post another since my symptoms are a little different. it seems when i get up near 90kmh or faster, theres a shuddering in the steering wheel. it seems to be temperature related too? if you get up to 90kmh within 15 mins or so of starting the car from cold, the shudder is there, but once the car has been warmed up for a while, it goes away. since the car will be going in for a big service soon i figure i should compile a list of things to check through Link to comment https://www.sau.com.au/forums/topic/219651-another-steering-shudder-problemhelp/ Share on other sites More sharing options...
Duncan Posted May 17, 2008 Share Posted May 17, 2008 shudder through the wheel is generally wheel balancing Link to comment https://www.sau.com.au/forums/topic/219651-another-steering-shudder-problemhelp/#findComment-3874196 Share on other sites More sharing options...
central coast person Posted May 17, 2008 Share Posted May 17, 2008 dont worry sounds the same as mine all i need is a wheel balance and alignments those are what i have been told it is (professional mechanic guy for rims and alignments and balancing drove it and its been conformed) so id say 99.9% sure Link to comment https://www.sau.com.au/forums/topic/219651-another-steering-shudder-problemhelp/#findComment-3874276 Share on other sites More sharing options...
Red Sky II Posted May 18, 2008 Share Posted May 18, 2008 I will be interested to see how you go with this as sounds similar to a problem I have had for the last 3 years - tried wheel balancing and alignments (at both tyre places and professional suspension places) plus put in a castor kit (made a difference) Is worse when colder and seems to disappear after a while Link to comment https://www.sau.com.au/forums/topic/219651-another-steering-shudder-problemhelp/#findComment-3875638 Share on other sites More sharing options...
zoomzoom Posted May 18, 2008 Author Share Posted May 18, 2008 yeh it seems odd, as all the tyres were replaced only 3 months ago, and barely 2000kms at that. the only other thought is something to do with the drivetrain...it definitely goes away once the car is warmed up substantially, so if it was a tyre balancing issue, wouldnt it always be there? are there any possible issues with bearings, diffs or attessa system warming up?

IMPORTD Posted May 19, 2008 Share Posted May 19, 2008 its not wheel alignment or balancing. I had the same issue. It is the power steering pump and fluid. Seems to be fine once the car has heated up. Check your fluid levels, give it a good flush with some new fluid and take it easy until the car has warmed up.

Red Sky II Posted May 19, 2008 Share Posted May 19, 2008 Hadn't thought of that Kylie, so will investigate Did you need a new pump or just a full fluid change?

IMPORTD Posted May 21, 2008 Share Posted May 21, 2008 just a full fluid change Link to comment https://www.sau.com.au/forums/topic/219651-another-steering-shudder-problemhelp/#findComment-3884778 Share on other sites More sharing options...
kidafa Posted May 21, 2008 Share Posted May 21, 2008 just a full fluid change Full fluid change being sucking all old fluid out of resevior with a syringe and re filling or is their something else too?

AndyD Posted May 22, 2008 Share Posted May 22, 2008 Just read the stroy in HPI of gtr brake upgrade this is the explanation it gives of brake shudder Qoute"In a nutshell if your getting feedback through the steering wheel and suspension when you brake at certain speeds and pressures,then you are experiancing what is known as brake shudder,This feedback can range from a faint vibration that is barely noticeable,to a series of shakes that are so bad they feel violent enough to almost rip the wheel from your hands. It doesnt matter if your on the track or the street,because it is caused by an uneven build up of pad materieal on the surface of the rotors. It is agrrravated by the high temps of the track and by the switching back and forth between two incompatible friction materials. It should also be pointed out that the shudder is the result of a thickness variation in pad build up on the rotor surface and not the popular myth that it is caused by warped rotors."end quote Hope this helps somewhat there is also a very good guide to bedding in brakes and pads but to much for me to re-type here i suggest everyone grabs a copy and has a read for themselves some very good info in there. The article also gives Hawk pads the big thumbs up for pads i read somewhere else on these forums that they make str8 swap pads for stageas so this may be of note to those needing to upgrade soon.

LOL just be aware that there are a couple of skyline owners (and a 350Z owner) that are too paranoid to brake near a cop car, using those Hawk pads, as they increase brake noise a LOT.

Duncan Posted May 24, 2008 Share Posted May 24, 2008 probably an installation problem - even the hawk race pads i use don't make any noise Link to comment https://www.sau.com.au/forums/topic/219651-another-steering-shudder-problemhelp/#findComment-3892265 Share on other sites More sharing options...
