I have a 91 hatch my car fells real slopy when i accelerate and when i hit a bump its not my suspension because i just put the tein ss on there what could it be i am thinking its my ball joins or tie rod ends

 

ok this might make me sound like an ***, but i'm seriously not trying to be one.

ball joints are part of your suspension, just like anything on there that moves up and down, turns, or guides it.

but yes, i'm sure your balljoints are worn. also could be your bushings. rarely, your steering gear can even go bad if the boots are torn on it.

usually, i just go all out and replace all the balljoints(and tie rods), sure they cost like 15 bucks a piece, but if your car's that bad everythings worn, even if its not worn to the level of play yet. check your bushings, too, and even check for play in your hub bearings (rare, but happens, especially if your car sat for a while, like in a junkyard or something)
