Oh, also figure on retorquing the u bolts a week after the job. They
'will' come loose unless you use an impact gun and really over torque
them the first shot, but even then it is worth a recheck.

I helped Norm Mitchell from this group do a spring lift and we torqued
everything properly. He didn't do a retorque and a few weeks later we
found him lost in the bush 25 miles from the nearest house with his
driveshaft laying on the ground because the springs came loose, the
center pin sheared, the springs all shifted and the axle shifted back.

He got lucky, he heard one of us, 'mad Jo' on her boosted all to crap CB
in the middle of a 10 Day RAMJ+W newsgroup run. She tagged him and the
other 7 of us ------ out on the trails trying to pick him up on our
regular CB's. One guy, Steve Seppala tagged him due east, so we all
headed that way while Jo sat on hill relaying the messages.
