Post subject:  SPEED WOBBLES

When im driving the zook...just normally whenever i get upto 60 KM the wheel shakes bad as from side to side. I put my head out the window and there is like a clicking sound when they shutter like a rattle. It gets pritty violent when the wobble get momentum.
To stop the wobble i have to jam on the brakes and they go away. Or even sometimes just accelerate through them which can be scary.

Anyway i replace the steering damper...fixed for like 1 day and they were back.

Other suspects are - Wheel Bearings

What do u guys think it is?

cheers Jake

Had a balance or wheel alignment recently?
If it isn't one of those items, then I would be checking the entire steering/front end out before driving it at all.

King pins or tie rods? Check all your bearings and steering. One of the hub nuts could have worked its way loose.

i had the same. i did a full swivel hub rebuild cos the rubber and felt was farked. also did the kingpins and wheel bearings whilst i had it all apart.. well worth it.. no more wobbles..
wheel alignments etc actually made it worse..

make sure your front end is all tight etc. if there are no other problems forget about a wheel alignment with larger tyres as factory specs are thrown out the window when say 31's are fitted. i've come across this problem a few times with larger tyres. set toe to 0mm, then go out or in until the wobbles have gone. different manufacturers tyres need different toe, and yes, it could be that simple.

i had this exact problem. even after a front allignment at 2 different places. got the printout from the 2nd place and everything was within limits. Fixed it by replaceing damper and adding a little more toe in.

Better now than its ever been

Wheel bearings, full hub rebuild, Kingpins including

Steering joints and box play

wheel balance.

I have had this heaps of times.. with tiny bit larger then stock tyres.
Went through all those steps, now run smooth 33's with loosish suspension!!

It was mainly my wheel balance i think..

Never had a wheel alignment :lol: 1.1/2 yrs ive had her..

okay time for more high quality Noobcad to explain

Too much toe out makes the car go stupid the front wheels are both trying to drive in different directions

Too much too in and the car is like a snow plough. Its just riping the tyres across the road and under braking it is hideooes ( like my spelling)

Zero toe in is stupid cause as soon as you accelarate or have any resistance from the road the tyres start pushing out due to all the moving parts. To get TRUE zero you need to compensate for the outwards movement of the tyres by toeing a litle first. Nice tight front end will give about 1-2mm toe in, sloppy as front end toe in up to 4mm

hope this helps explain toe in out

PS Vitarda have a different steering set up to Sierra. Lj have a very special sytem all to them selves
