hey guys im new here just joined today, i bought a 03 PT touring about a month ago.. and its great.. fun in traffic scoots around everything unlike my ram 1500 sittin on 35's lol... well anyways.. ever since i bought it.. when i put it in reverse it has some kinda bad viberations.. not really to sure what it could be.. anyone else have this problem? i also noticed that when i put it in different gears it jumps or bucks.. also at low speeds between 0-15mph or so.. the steering wheel goes back and forth.. could this be happening because the tires/wheels are out of balance? one last question.. i went to work last night, and it got really cold out (37*F), and i left work this morning, and i lost all of my power steering.. it wasnt making any noise or anything... the wheel got hard to turn and it was gone.. i checked the fluid. it was a little low.. i added some.. drove around.. and it didnt come back.. i let it sit for a while.. then went n drove again and it finally came back.. i looked under the car didn't see any fluid leaking or anything.. so i dunno whats goin on.. any insite or help would be awsome! it only has 57k on the ticker and still under i think its 5 or 7yr/80k mile drivetrain warranty i think it is... thanks guys
