Tyre wear/wobbles/bump steer :(
Hey folks,
I have my front left tyre wearing out on the outside edge of the tyre much more than the inside. I also have considerable bump steer/wobbles when i hit bumps on the bitumen.
I have always had a tiny bit of bump steer as i have a small lift and taller tyres. As such i am fitting corrected caster bushes soon.
However the new problem with tyre wear and wobbling crazy bump steer and the car kind of feels like it wants to drift all over the road is totally new.
I have a pretty new steering dampener. Prying the bushes on the panhard rod and radius arms results in no excessive movement (in my opinion).
Steering rod balljoints are all reasonably new (heavy duty steering arms). The wheel alignment seems ok - not sure if wheel alignment would result in wear on only one edge of the tyre anyway.
I read an old thread or so on the forum about the wrong preload on swivel hub bearings could be the cause. I could check the bearing preload again but I did check for play in the hub by trying to rock the wheel back and forth and there is not movement left or right or up/down.
With this pattern of tyre wear presumably the problem is just the camber? If so, what could be wrong with the swivel hub that results is such excessive tyre wear on the outside edge, yet results in no play when rocking wheel/hub?
I am unsure how lack of swivel hub bearing preload (slightly worn bearings) could the extent cause these kind of problems - after all the hub is connected with a couple of steering arms to keep it from unwanted movements...
Thanks for any opinions!
