I'm driving a Jimny SJ-410 (1985) on Bridgestone Dueler 30x9.5 AT Tires and had installed Wheel Spacer/Adaptor (4 cm thick).
Problem is, while driving at around 60-70 km/hr speeds on asphalt roads, the vehicle swings all over from left to right. Tried tightening the Worm Gear/Nut but it only helps for a short time and then I'm back to the same old problem again.
The short terms solution of tightening the Worm Gear/Nut wears out the internals of the steering gearbox (see picture). Every 2 ~ 3 months, one of the following would be worn out and requires replacement.
1. Fine Pitch Worm gear
2. Ball Bearings
4. Sector Gear
Friend of mine told me this is a usual problem using the Wheel Spacer. I've tried taking them off but the problem still sticks.
Any hints and/or help would be much appreciated.
I have run quality wheel adapters (spacers) on my zooks for over 10 years now and that is not the fault of the wheel spacers.
Two things I would check right away.
1. Is the steering damper (shock on the steer) still good? If it is real easy to open and close then you want to replace it.
2. Have you changed the angle of the front axle?
I see your rig is lifted. Is it SPOA? (Spring-over-axle) or just longer shackles?
When lifting the front you have to make sure you retain the factory caster angle of the steering 'ears'.
If you don't, then it will wear out your components (worm gear, steering box)much faster than normal.
