rear end vibration from 4runner ? (1 Viewer)

[kenwin30]

ok guys, here me out on this one, about 6 months ago i noticed a vibration-pulsation coming from the rear of my 4r, it tends to happen at 55 mph and above, it seems to be coming from the right rear tire, new tires, new u joints, new drive shaft, new right rear wheel bearing, new brake drums and its still there, had a couple of mechanics take a look at the 4r and they say everything looks fine, but trust its not, gona take it in for a road force balnce fri, if this doesnt fix it i might just have to live with it, anybody here got any ideas to what could be causing this ? thanks guys

I would be thinking tire/rim balancing especially if it is a factory alloy rim.. https://forum.ih8mud.com/95-gen-toy...ancing-problems-my-99-4runner-alloy-rims.html
next I would jack up the rear corner and use my poor mans dial gauge by setting up a pry bar/pointer on a box or blocks and then spin the rim and tire to see if you have excessive run out in any direction. Tire could be out of round or starting to separate.look on the insdie sidewalls of the tires as well for bulges.. or rim could be bent.
Next I might look at allignment of the rear end.. measure/look at each rear tires position in the wheel well compared to the other side.... has it ever been in an accident ?
