Further to my steering wheel shake ......
Further to my steering wheel shake ......
Just had a new set of Superior Engineering 2" caster correction bushes fitted hoping that may fix or reduce the wheel shake. Well it did something. Now, at 110klph and over, not a hint of a shake or wobble. Vastly better than before.
But now, at exactly 80klph it's nearly a "tank slapper", very dangerous, and much worse than before. One of the front wheels previously required heaps of lead to balance. I'm hoping it is a wheel problem because I may sell the steels & muds and put some AT's on the mags if I have to.
Today ...
I've just had a wheel alignment, balance & rotation which has discovered an issue. The two front tyres are badly "out of round", they have many high spots which may be causing the problem, although there is no obvious unusual tyre wear. The two rear tyres are perfect. We've swapped wheels front to back and the 80klph "tank slapper" is gone, hopefully permanently. What a difference, makes driving much more pleasant. The shop seems to think that two of these tyres may be faulty and has reported it back to their supplier, as this is the shop I purchased them from. Them seem to remember a similar circumstance around to time I bought mine from them. Who knows, something or nothing may come from this. I've "over inflated" the suspect tyres to hopefully run the centers down a bit. If that does nothing I may replace them or swap the lot to AT's.
Anyway ...... at the moment I'm very happy with the outcome. I hope I stay that way.

A worn lower panhard rod bush is a common cause of the wobbles, but not always the fix. I used to have Nissan steelies, they were crap, so I bought some ROH steelies, and it was better, then I readjusted the wheel bearing and it was gone totally. Then I bought some Alloy wheels, and its back, but only just slightly. Kinda wishing I never went the alloys now... I still got my steelies so I may even swap them back one day.

Do you rotate your tyres to keep the wear even.?
maybe slow down a bit on the corners around the Burbs
that will stop the fronts from scalloping out

How did you adjust the bearing?

With a hammer and pin punch and nipped them up so there was zero play in the wheel.

I wouldn't call it scolloping it's more like "lumpy", and it's only in the middle of two tyres, not the edges. If you hold a straight edge against the center of the tread, the "lumpyness" is unevenly spaced around the tyres. Their on the rear now so we'll see how they travel.

As far as i know thats caused from the shock absorbers not working as they should.

That's what I thought, and was also suggested by the tyre shop, but the shocks & coils are Dobinsons and only about 18 months old and show no signs of wear or failure. The question is .... were the two tyres faulty from new, which caused the excessive wheel shake, or was it a suspension/camber/caster etc ... that caused to tyres to become "out of round". ??????

Camber wouldn't make them out of round, just uneven wear to one side of the tyre.
