    Have noticed my 74 has a lean on it to the right (drivers side). Did some measuring today and it's around 15mm difference. Doesn't sound like much but it's quite noticeable especially from the rear. Some say it could be broken front springs or need to adjust rear torsion bar....any other input???
    Cheers

    Repeat measurement with 3/4 fuel load and think its 90kg in drivers seat.
    Actual rear set is determined by degrees of spring plate.
    Correct tyre pressures 30f 38 r.

    Fuel is on 1/4 today and will check all tyre pressure. I have a twin exhaust on it and it looks like the exhaust it croooked but infact it's the bus. Can you move spring plate to even up or adjust the torsion up 1 notch?

    Tried it but heavy driver also. Might have to convert it to LHD

    The number of splines on inner and outer of torsion bar are different.
    It is possible to calculate and adjust both to give small increments.
    One spline on the outer only will be too much. Equals about 23mm height gain.
    Check all the basics first tho such as *doing the angle check with correct loadings.
    *checking rubber bushes on torsion bar are good.
    *checking torsion bars are same colour code.
    *does exhaust look 'out' compared to body or relative to ground /same as bus. You may have an accumulation of items being ' out of alignment' ?

    I didn't read your first post correctly.
    Thought it was left rear down.
    Is it a camper fitout?.

    Will look for a relevent " how to"

    Hey Borgey,
    Sounds like many miles with just a driver. My guess is spring plates in front torsion beam cracked. I did my front beams with second hand at 400k & rear torsions at 500k. How many km's?
    Cheers

    No it's an 8 seater microbus. Drivers side is tilting front n back. Looks like the whole thing is leaning to the right. Took measurements from ground to wheel arches and it sits 15mm lower

    With the bus on a firm level surface take rear wheel arch measurements. Jack up the front of the bus until the front wheels just clear the ground. The jack must be exactly centred under the front beam. Naturally the bus should have any heavy items removed.

    Retake the rear measurements. If the back of the bus is now level your torsion bars are ok,you need to check your torsion leaves at the front, a messy job.

    Also check that you don't have different shock types skewing your results.

    If the back Is still uneven, you can repeat the above process in reverse, place the jack under the torsion rear end near the trans mount.

    whichever end of the bus is level while the other end is jacked up, your problem lies at the opposite end.

    If theyre both uneven you have sag both ends.

    That's what I need to hear. Elimination process to find the culprit. Will get onto that over the weekend and let you know the result. Thanks for the input everyone!!
