4ws help needed

[eternazr]

Hi, Hoping that someone can answer my question.I sometimes hav slight wobble happen in the back end of the car when i am around 100 kmh mark, it almost like the 4ws is doing it's own thing, making the car feel unstable on the road.I brought this car knowing it had this fault, with a plan to fix.Has anyone else came across this issue, please let me know, cheers.

I have seen realy sloppy steering pin dia to trailing arm hole tollerance.
That slop allows the trailing arms to wonder while the steering is held straight.
If that's your prob, you could search for a decent set of rear arms or sleave them.
Cheers !

jack and block up the rear end, preferably under the arms somewhere strong so it is similar to the road going height and push pull (up down left right) the wheels feeling for sloppiness.
if sloppy, get the mrs to climb under and find the free play. there is your problem...

might as well check the front as well, while you are in the frame of mind
