I was wondering if any of you diesel guys that have extended cabs or crew cabs have 1 piece driveshafts. Are you 2WD or 4WD? Is it aluminum or steel?

The reason I ask is I heard that the D-max trucks don't have carrier bearings and we all know they make a ton of torque so I'm interested in adapting one to fit my truck. I'm going to need my current 2 piece extended about 2.75", which is the wrong way to go if I want a 1 piece, but I'm exploring my options.

 

ill have to look but im pretty sure my dads is a 1-piece its a 04 2500hd dmax/allison ccsb 4x4 i think its aluminum too but not sure

 

just went and checked it is a one piece aluminum on the above mentioned truck

looks to be about 3.5" around too didnt measure it but thats what it looks like

 

Mines a one piece.

 

Both of mine are two piece steel with carrier bearings. Seems the General never had much rhyme or reason on which trucks got a one or two piece driveshaft and whether they were aluminum or steel.

Both of my two piece driveshafts are holding up well.

 

Can you snap some pics of it? Particularly the carrier bearing. I'm interested in seeing the yoke on the 2nd driveshaft.

Can anybody measure how long your 1 piece is from u-joint to u-joint?
