Hi
Ok bare with me on this because im going to try and give as much information as i can on my problem ...
Steering wheel wobble between 45-55 mph typical of wheels needing balanced , however it doesnt happen all the time .
Its only occasionaly .
Its through the steering and not through the car .
I can accelerate slowly from 40-60 and it doesnt happen then the next time it does ... there is no pattern to it and its getting on my nerves .
I have had a new GM steering idler and trackrod ends , drop links , GM brake discs in case one was warped .... however the brakes now squeel :-/.
I have even got new wheels and tyres and had them balanced and checked at three different places but it still shows up now and then . Every time they say the wheels are fine and dont need balanced but re-do them anyway .
It also did this with the old wheels ... i got new ones because i thought maybe one was bent .
There are no knocks etc that i can hear from the suspension :-/
The car when wobbly feels horrible to drive between these speeds but feels fine under and over these speeds .
The hubs were spotlessly clean before the new discs went on .
So what am i needing to do beore i go mad with it ... it has just passed the mot with no advisory so does that mean the wishbones are fine ?
I dont understand how its there one time then not the next on the same strech of road ...Obviously something that rotates is running out of true but what do i check next before i unleash the matches

Sorry for the long winded story but im getting desparate now to have a nice wobble free drive .
Thanks
