Why is my driveshaft...

OK, here's how I understand it:
All 2wd's get 2 pcs steel.
All CCLB's ditto.
Short wheelbase (RC/ECSB) 4x4 get one piece steel.
Everything else (CCSB / ECLB) get's a one piece aluminum, due to the length.

When a single driveshaft goes past a certain length, they need to switch to aluminum, which is more expensive.
And if it goes even longer, it has to go 2 piece. This is CCLB.
All two piece driveshafts are made of short pieces and can be made of steel, so all are. 2WD's have to be two-piece because there is no slip-yoke in the trans.
So it has to do with the length of the longest segment:
The 2wd thing had me puzzled until recently. I didn't realize the Allison doesn't use a slip yoke like other transmissions. In the 4x4, the transfer case has the slip yoke.

So it has to do with the length of the longest segment:
- Short truck - 1pc steel.
- Medium truck - 1pc alum.
- Long truck - 2pc steel.

Hmm, didnt know that either, bu ive never seen underneath a 2 wheel dr. DMAX,
Interesting info Pat.
So what do These cars like the Chevelle with the Dmax/ALLY, and 65 Impala/PPE Pimp my ride use to take up slack? A CV driveshaft?

If the driveshaft is short enough, they can run a 1 piece with a slip end. If it is more than 50" or so, then they have to go 2 piece. Ours are like 80"+
Hmmm I never knew that the alli had no slip, I like learning things. I wanna polish my drive shaft

I used ZepAlum on mine, its looks brand new.
maybe off topic :hug: but,
I was reading Merchants recommended maintance list and he has lube driveshaft splines. I was looking at the truck today and I didnt see what to lube
Do I need to do that with a 2wd truck?and is this what I'm looking for?

Just a guess...but I would think he means to pull out the slip yoke and grease the splines inside the slip yoke. Thats what I did when I had the driveshaft out to replace the output seal...I used wheel bearing grease.

No the splines are the slip yoke. According to pat 2wd allys dont have a slip yoke so there shouldnt be any splines to lube.

I missed the 2wd part...I forget they make those
my buddies 01 EC LB 4wd has a two piece steel and my 06 2wd EC LB dually has a 2 piece steel as well FWIW. and the 01 CCSB had two piece steel. It wasn't until 02 or maybe even late 01 that they went to one piece alum. on the CCSB I think due to driveline vib issues from the steel ones.

All driveshafts have a slip somewhere. The 2wd driveshafts probably have the slip at the carrier bearing.
