I just replaced my slip yoke for this very same problem.
Could be pinion bearings or preload too.

I'd assume your Bronco is 4x4, but I know some southern trucks were not.
In a Bronco I think the TC would have a flange, rather than slip output.

But it is still best to look VERY carefully for any freedom of movement at both ends of the driveshaft.

Welcome to the forum.

Check all mounts. Engine, trans, does the Bronco have a carrier bearing on the drive shaft or is it too short. Anyway, check all rubberized mounts that have anything to do with the drive line. Good luck
