Hi guys,
This has been asked before but I can't find an answer to my question.
Every manual or step by step writeup says that you shouldn't remove the torsion bar from the inner spline location.
Now, I did offcourse do that and now I'm in trouble.
Thankfully every part has been cleaned, new bolts and rubbers so the task will be easier.
Now I'm improved technically :roll: but still I don't really understand this;
"There are 44 splines on the inner end and moving one spline changes the plate angle 8.18 degrees.
There are 40 splines on the outer end and moving one spline changes the plate angle 9.00 degrees.
Neither of these is the "fine tuning". The two used _together_ is the way that you adjust the angle. If you turn one end one spline and the other end one spline in the opposite direction you will get an angle change of 0.82 degrees, which is the tolerance allowed for the spring plate angle. Thus, there is always one setting that will get the torsion arm into the correct angular range. You measure the current angle of the spring plate, find the difference between that angle and the desired angle, divide the difference by 0.83, round to the nearest integer, turn the torsion bar in the inner spline by that number of notches _opposite_ the desired direction, and move the spring plate on the outer spline by that number of notches _in_ the desired direction. Check the measurement and you're done!
If you try to adjust the angle by just turning the outer spline, you will end up with the rear end way too high, like against the upper stop. The bus will handle very strangely, will have horrible rear tire wear, will ride very roughly as the suspension tops out, and will damage the CVs and boots."
So again I need to know how to be sure you inserted the torsion bar correctly so you can measure the outer splines for the spring plate?
Don't know of any garage that could do the work for me so have to take care of it myself.
Thanks,
Nate
