I am nearing the end of my zf swap. Unfortunately, the shaft off the donor shaft will not work. Seems like I'm about 1.25" short. I am assuming this is because I am keeping my 4407 Tcase rather than the 1356 that was in the donor.

I am looking for the length of the front part of the rear, 2-piece shaft on an extended cab long bed obs 7.3. I am going to have mine lengthened and want to make sure I measured it correctly. Found a few posts, but none with the length for my body style.

If you don't know the exact length because of the slip joint, a measurement from the carrier bearing forward would be just as useful.

Ok, can I just measure the difference between the E4od (31 3/4) and the ZF S-542 (26 1/4), which is 5 1/2 inches, and then have them add that length to my original drive shaft?

Dose anyone else have measurements for these 2 transmissions? Could not find them listed anywhere on the site.

 

I just grabbed a tape measure and made all of the measurements on the fly when I had mine done. They made it according to those measurements and it went right in without any problems. My E4OD is sitting in my garage still. I can measure it for you tomorrow, but if you've already got the transmission and T-case installed, just take the metal bracket that the rubber bushing of the carrier rides on and bolt that in without the shaft in there. Then, make the measurement from the flange to the center of that metal bracket deal. Also measure from the flange to the yoke to the rear end. You may want to go ahead and have them do the carrier and U-joints while they're at it.

 

Thanks Buckhammer.

I took those measurements, and am having my dad drop it off at the driveline shop tomorrow. Having the carrier and u-joints replaced as well.

Lord willing, this time next week I'll have the zf swap completed and be cruising the dirt roads...
