I had a look at my torsion bars today and found the bolts on the drivers side is wound up further than the passenger side.

Measurements from the wheel arch to the hub are the same within a few mm's

IS this normal or an indication they have been played with because they're stuffed?

They appear to be standard Toyota bars.

Cheers

Andrew

Andrew,

The drivers side is normally a bit higher that the passenger side. You will always have a driver in the vehicle.

The rear springs can also effect the setting of the front torsion bars.

Winding up of the front torsion bars will help to get the vehicle to sit level and it is not unusual to have one bar would up more that the other.

They could have been adjusted when the bull bar went on.

Thanks Wayne.

Do you also know if it's just a simple matter of 'winding' up or down the bolt to adjust these?

Does the front end need to be lifted off the ground prior to adjustment so the wheels are off the ground or can it be done under load while the vehicle sits normally?

Andrew,

I have always adjuster the torsion bars with the vehicle on the ground.

Measure the height the way that you said, adjust the height, bounce the front of the vehicle by pushing on the corner of the bull bar and re measure.

When it is close take it for a drive and remeasure. After 1000 km repeat.

The torsion bar adjusting bolts have a fine adjustment. One turn of the bolt might lift the vehicle 0.5mm. There should also be a lock nut on the adjusting bolt, this will have to be wound off and lock back after the final adjustment has been made.
