Ok thats just plain silly.
As for the issue at hand. 50k miles...one of your weights on your drive shafts might have come off.. They are welded on..but I have heard of this happening..
The rpm issue...would result in the drive shaft.. preferably the rear. Did you have your gears changed in your diff's...? If so, then if its not your gear's...then its your drive shaft's..
Another possibility is your ball joint's...the lowers go first ..before the uppers...its possible ...if this is a doubt, jack up one side and move the tire up and down...if you hear and see a slight movement..your ball joint's may be bad...which causes your tire to have more play in it when driving.
