Great site First of all last week replaced front U joints the hub bearings looked ok the rest of the front end looked ok as far as i could tell. The problem i haveing has always been there even before i changed front U joints. When i turn all the way to left the left wheel wants to sort of jump up and down. Its like the wheel wont turn smooth like something loose but front end feels tight. The right front is fine. The truck is 2001QuadcabSport 4x4 5.9. Any ideas need help Thanks guys
