thought i'd post my related results in the correct thread:

get those torsion bars adjusted correctly! i just did mine and man what a difference! started under 8" ground clearance and got them adjusted so van is sitting about 9" - close to what the manual calls out

my van has new shocks but i think they were bottoming out before as i could feel every minor bump and lots of squeaks and noise. used to dread going over rough roads but no more

made a huge difference. drivers side was slightly lower than passenger side as well

you'll need (2) two 22mm wrenches - got a couple at the used tool shop near my house.
