serious wheel wobble jimny

hi ill start from the beginning , i went off roading last week and went down a track that made the jimny bottom out , after doing 80miles around the lanes and then driving home upto 60mph all was ok , then i discovered my valve was knacked on the rims i had , so i gave the tyre to my mate who put me a new valve on , he didnt balance the wheel after he did it.
then tuesday last week i went to the cinima in the jeep and i got an almighty wheel wobble when i go over bumps and potholes in the road and its that fierce i have to stop the car for it to stop .
now after this i checked the radius arms and found that id bent the drivers side , now ive replaced that today and just been for a drive and the damm thing is still doing it, ive checked for play in the front wheels and there is very little play at all , do you think it because the wheel wasnt ballanced when my mate did the valve???
if i cant find out what it is im going to scrap the jimny as it feels really dangarous:(
:dry:

If it starts up after hitting something rather than being speed related it sounds as if you have damaged something that contributes to steering damping, and the only things that do that are the Kingpin Bearings and the rubber seals on the back of the hubs. When you say that there is no detectable play in the wheels you did check this with the car jacked up didn't you?. I suppose it could also be a knackered shock absorber - have you tried bouncing the car?

Wheels out of balance tends to show up at a single speed any faster or slower then it goes away.

Whichever way it is not worth scrapping as any garage worth its salt would be able to diagnose it for you

does it at around 30mph , and only whan i hit a bump or pothole yes i jacked the car up and did it up and down and side to side , the only play is the steering moving and thats normal, the scrapping part i was mad when i wrote it:angry:


just jacked it up again , bothe wheels off this time and ive got slight play when i rock it left to right , but everything rocks all steering arm ect , ive just noticed the front panard rod is bent aswell , (happy days):laugh:

took it to the garage round us and he had a drive in it and nearly crashed with the wobbling it was like driving a clowns car with oval wheels it was that bad , but only when i go over a biggish pot hole at 35 to 40 mph , he checked everything like wheel alignment and camber , play in anything ect and he found nothing of the obvious , the only thing is ive got a very slight bend in my panhard rod but hardly anything .
if my king pin bearing is knackered what are the symptoms , there is no oil res on the innerhubs or any sort of play just what you would expect , im really stumped on this and ill have to resort in an expensive garage bill if the worst comes to worse.
ill try to do the work myself but if i get stuck the garage is always the last resort

If it was the Kingpins I would have thought any garage worth its salt would have picked it up straight away.

Perhaps you need to have someone watching from outside the car, perhaps from another car when it happens. Its a shame you do not live closer as we could get together and investigate further.

(a possible cheap way of getting it investigated is to put it in for an MOT!)

i got the other guy from the garage to drive it and i was in the passenger seat , and when it happened i looked down at the front wheels and they were wobbling all over the place just like somone was turning the steering wheel back and forth fast
