F350 double cardan front drive shaft so no vibes with hubs locked on highway
Can you elaborate just a bit? I get this and I'd like to implement soon for the exact same reason.
replace the T case yoke with one from a F350 with 1356 tcase ad get a NOS driveshaft from a F350 off ebay and install. Easy install and no vibe. There is a vibration TSB for all broncos that lists the yokes and part numbers for driveshafts and anybody who complained of vibration with hubs locked on highway.

This TSB article is republished in its entirety to include 1996 and 1997 model year vehicles.
A driveline vibration or noise may occur when driving a 4X4 truck at highway speeds in a 4X2 mode with the front drive hubs locked. This can occur if the driveline angle is incorrect.
Replace the front driveshaft with one that has a double cardan joint at the transfer case and a compatible companion flange for the transfer case."
