Ok Just got the gf a 99 F350 crew cab long bed with 154,000 miles. When we got the truck i made the dealer fix everything wrong with it part of the deal, so i didnt have too, but that included torque converter, vacuum lines, brake lines, and hub bearing. Well before everything was even replaced i knew the truck was getting some vibrations, it sounded like going over rumble strips at a stop sign when you hit bumps at random speeds. Well i figured it was from the hub bearing cause it had about a inch of play. well now everything is replaced its still doing it, i checked all the joints and bearings everything is tight.. another thing i noticed idk if related but when u go over a bump it sounds like Pogo stick on the driver side real squeeky. what would cause that? i know the sway bar bushing on the mounts could be replace but they dont even clunk real bad like my truck did and mine never squeeked. thanks everyone all the help could use.
