steering shake

[rainster]

hello people i have a question to ask i hope some one knows.i have a nissan skyline hr34 and i have being experienceing a shake through the steering wheel at about 100km.i have had 3 wheel alighnments and 2 wheel balance on all tyres i cant seem to get rid of the problem it irritates the hell out of me ,so i decided to check the suspension out i noticed that i have had 1 radial rod replaced but notthe other when looking at the bush there appears to be small cracks in the rubber but no grease coming out ,which i had same problem with an old skyline of mine which bothe bushes leaked grease.is it possible that all the grease has leaked out of this bush alreasdy or are the hr34 bushes dont have grease fill bushes anymore.if so is this bush possibly my problem as my rims and tyres have checked and have found to be ok also i have got locater rings installed for my rims.i have checked my top arm bushes ball joints etc .im hopeing some one else has had this experince and replaceing the bush has fixed it as my bush hasnt completly fallen apart to make me think that this is the problem and a bit reluctant to waste heaps of money to locate the problem,help somebody.

Hi, I dont if its the same on the R34's but I know with my R32 that the wheels have to be balanced within 5 grams, some places dont balance that accurately.

Also when you checked your tyres, did you see any bulges in the tyres, also some tyres dont stay perfectly round and will wear and go out of balance.

You havent flatspotted the tyres or anything?

Failing that is your steering rack ok, maybe its had a wack from a curb and damaged inside.

Jack the car up and see if there is any loose/rattling movements from rack.

Yeah make sure that the rack is securely bolted down.

Get it up on a hoist where you can have a clearer look at it.

Get back to us with your info as well.

i have jacked the car up and check for play in the rack i dont think its that because with the engine off and wiggling the wheel no power steer the doesnt appear to be any excessive play or noise also my steering doesnt wander and there are no abnormal knocking noise when driveing over bumps in the road ,i think i will replace both caster bushes and see if that sorts it it will cost me $80.0 and i use my press at work to press them in i.i have my fingers crossed when test drive it hears hopeing.

Could be ball joints.jack up the front again and see if there if any free motion/rattlilng by shaking the wheels with a side to side up and down motion.And if the movement feels like it is more than what should be it could be a problem.

I know when i took my suzuki swift gti when i had i back in the day to have it blue slipped,I was knocked back on ball joints.

You have checked the tyres and made sure there is no abnormal tyre wear on the very inside, etc I hope?

Also just rotating the tyres may make a difference. Tyres can sometimes develop lumps in them if there was an error during manufacturing.
