borg warner t-case issue
Hi,
I'm working on a 1990 Bronco and I just swapped out a BW 1356-E for a 1356. I was told that the 1356 came out of an '86 f250 and would bolt right up. But the 1356 uses standard not metric bolts and the rear yoke is a slider NOT a fixed like on my Bronco. I tried to put my fixed yoke on the new case but the shafts are different sizes. Has anyone dealt with this before? How did you solve the problem. Is there anything that came stock with a large diameter fixed yoke? Should I just sell this case and get a Bronco t-case? Any help would be greatly appreciated.

I have the same issue, swapping the 88 F-350 drivetrain into my 84 Bronco. The manul BW 12-56 from the F-350 has a slip yoke rear output, so I bought a used electric BW 13-56 with a fixed rear yoke. I'm swapping the output shaft and fixed yoke from the electric onto the F-350 case. Since the case needs to be split in half to replace the shafts and yoke, it's a good time to fix the oil pump mount on the inside of the case, which is a weak point. FYI, the F-series pick-ups and Broncos have different yoke sizes, so a Bronco driveshaft will not fit a F-series t-case. Yo ueither have to modify the Bronco driveshaft with the F-series matching yokes, or swap yokes on the t-case for ones from a Bronco. It's easiest to swap yokes, but you'll likely have to buy a whole used t-case as I did for $100. JSM84
