Drive shaft orientation
I have a 78 F-150 4X4. What is the correct orientation of the rear driveshaft? Should the slip yoke be at the rearend or the transfer case? Also, my truck is a long wheel base, should I have a CV joint? The truck is lifted 4 inches. Thanks.

Drive shaft orientation
I have a 77 F150 with about 5"s of lift and my back driveshaft has a Cardon bearing at the Transmission and the slip joint at the back rear end. Not sure if this is correct, a local mechanic says he has seen them both ways. But he said that the Cardon is needed with the lift. Hope this helps.

Drive shaft orientation
The slip joint should be at the diff, the "breather" is on the end of the short shaft, to run it at the 'case would allow water/dirt to lay in the splines(rubber seal on slip end). As long as you can keep the angles at the u-joints close to the same on both ends of the shaft without binding when at full droop, you'll be ok with what you have(although, more angle=less life). If the angles get to extreme, then you might want to consider a double(CV)at the 'case, then the angle into the rear should be as straight as possible. They do make shims that go under the springs to adjust pinion angle. CV's are considered a must on lifted short wheelbase trucks. Hope this helps!
