I AM GOING TO LENGTHEN MY REAR DRIVESHAFT ON SATURDAY JUST WONDERING IF ANYONE CAN GIVE ME A HAND BALANCING IT???????????????????????????
I SPOKE TO DRIVE PRODUCTS FOR QUITE AWHILE TODAY AND THEY SAID IF ITS CUT OFF STRAIGHT AND LINED UP PROPERLY IT SHOULDNT BE OUT MORE THAN A 1/16"
AND IF IT IS OUT JUST HEAT THE OPPOSITE SIDE AND HIT IT WITH COLD WATER AND THAT SHOULD BEND IT BACK.

A buddie did his own shafts
run a dail indicator at the welds, and just keep it fairly straight.
Tig welding makes it easier cause when you 'heat' up the opposing sides you not adding more weld.

Ben did an article on DIY driveshafts a while ago ( it's posted on the OTT site)...
LARS also did a driveshaft article and it's right here....
Balancing a driveshaft is really no biggie..... you are not exactly driving a rolls royce here.....as long as the results are relatively straight and the -joints are in Phase...the vibrations should not be too much .. regular hose clamps can be put around the driveshaft as a rudimentary solution to balancing ( the tightening screw becomes the "weight" )
