Ramcharger vibrates after using 4wd

Dragging brake shoe, broken transmission mount. Possibilities are endless. Broken centre pin in spring pack and diff moved. Easy to drop driveshafts and check for binding or a bad pinion bearing.

wheel weights knocked off is another.
4 new tires yesterday with same problem after. Has all new bearings in rear housing about 2,000 miles ago. I have new trans mounts that I can replace as well.
