Rear Wheel bearings - what type?

in most cases they would list both sides for the in-experienced countermen/women who cant digest the fact that they are the same bearing side to side .. if you check the part numbers if thats available. they should be the same. try your local NAPA store too.. i dont see why it would be different. but i also believe that TRB are your better option.. back in my first year as a mech. apprentice they taught us the difference about TRB and BB.. its a very big difference in how it distributs the wieght and torque and just the general design makes more sense even under extreme conditions such as dragging.. and thats my .02 as well (mind you its canadian, so like 0.00576)
