Rear 2 piece drive shaft question

[stoney126]

Hey all In the process of lifting my crewcab and it has a 2 piece rear driveshaft. My question is do I take both pieces to get lengthened or just 1 piece and which one?

How much are you lifting it? If your not going too high Im sure you can get away with just that little drop spacer that goes in between the carrier bearing and the frame. Otherwise from the looks of when I lifted my crew cab (I didnt need to lengthen the driveshafts) but it looked as though just the rear part of the shaft would need to be lengthened. Im sure someone here will be able to definitively answer that.

Unless you are moving the T case, I don't see how the distance between the back of the T case and the carrier bearing is going to change. They are both bolted to the frame, not to a movable part of the suspension.

Second this. Put a spacer between the frame and carrier bearing. Its cheaper and easier to do.

Yep, especially on a long wheelbase you can.

No, no, don't use washers. Stay away from washers especially on something crucial like driveline related parts.

Use solid stock and drill holes thru them in the thickness you need. I'd get some hollow tubing and determine how thick you need to space it down and then when you are satisfied, get some solid stock and drill the holes out. Using solid stock will give you a peace of mind knowing you have something bulletproof under there.

I have 12" leafs (or supposed to be) and my stock 2 piece shaft worked fine... dropped the carrier bearing a few inches using square tubing.. drilled holes and used longer bolts...... works fine...
however I have some wobbleing from time to time.. if I launch hard enough I can get the rear tires to hop off the ground.. you should see peoples faces!!!
