[updated:LAST EDITED ON Feb-28-04 AT 06:25 AM (CST)]I HAVE A 1975 CHEVY STEPSIDE WITH 6 INCHES OF LIFT WHAT IS THE BEST WAY TO GET THE PITCH OF THE DRIVESHAFT AND REAREND BACK RIGHT SO THAT IT DOESNT KEEP BREAKING THE UNIVERSAL JOINTS

with 6" of lift, that is a lot of angle to correct, I think you can correct up to 4" with angle shims ( mount between the springs and the saddles and change the angle of the axle to the driveline by rotating the axle back which tilts your pinion up more in line with your driveline.) I have heard of guys making a custom driveline by putting the double jointed c-v joints on one or even both ends of the drive line which will give you a little more give,reduce that extreme u-joint angle, not to mention reduce vibration,and/or combined with the axle shims. the only other thing I is to look into an axle flip,.. that is an axle that has been flipped upside down so the pinion sits a lot higher, of course there are setbacks to this, lubrication issues, I think you have to go to a 4x4 shop to see how much it would cost, or feasible this would be for you. I can't rember if you have to change the transfer case or not..
You could also drop your engine/tranny/transfer case a few inches but you are talking a LOT of work,
I would try axle shims, ( which usually comes with a lift kit,) question, is your back axle lifted by blocks? or by springs? with that much lift I would imagine you have springs. see if have shims on your mounting pads If not, you might be able to just use the shims
Hope this helps you out,

anyone else have any ideas????
