4" one piece driveshaft
Hi all, carrier bearing went. Went to local shop and got a quote for a one piece. 4" aluminum. 71 inches long. I searched the forums and some threads I found said it would work, some say no. I'd like to know who's running one and if how much you cut around the crossmember. Thanks!

Re: 4" one piece driveshaft
I'm running a 1 piece in my 71 LWB and it works great. Didn't cut a thing. Mine is a 3" static drop.

Re: 4" one piece driveshaft
Wouldn't the drop cause the driveshaft to go up towards the top of the hole more? I'm at factory ride height and idk if it will cause issues. Yours is a 4" as well?

Re: 4" one piece driveshaft
I have a 4" one piece in my 63 long bed. I did have to make the hole in the crossmember larger at the top for clearance when I air out. My truck came with a 3.5" driveline,when I had the new one built they talked me into a 4".. If I had it to do over again I would have stayed with a 3.5"

Re: 4" one piece driveshaft
We always made them out of 3.5" there might be clearance issues with trucks that haven't been lowered.
Why do you want aluminum? Show truck?

Re: 4" one piece driveshaft
Iv got a 4" aluminum one piece in my stock height long bed. I probably could of gotten away without trimming anything but it was a little to close for my comfort. If I remember, I was worried about my axle dropping to low (I drive thru a lot of fields and I always seem to be able to find every sink hole) and the drive shaft hitting the bottom of the crossmember.
I thought about putting limiting straps on the rear end but I ended up cutting about an inch all the way around.
