I'm looking at installing an axle bearing repair kit into my rear end. I happen to believe that one of the axles is damaged but I am not for sure. These kits push the bearing back farther. I'm worried about putting extra stress on the axles with the tires being 33's. Am i just being overly cautious or is this something I should truly be concerned with?
Here is the part I am talking about
