if I drive slow.. the car will pull to the right... but not like the typical unaligned car. It will pull to the right... straighten, pull, straighen... like a see saw. does that make sense? when u look at the steering wheel when i'm going slow it'll look like i'm turning the wheel quickly every half second then letting go...

also, when I stick it in reverse and don't touch the sterring, the steering wheel with turn really fast counterclockwise until it can't turn anymore.

i suspect its a tie rod worn out (cuz last time I got my alightment done, they said one was worn out)... any ideas?

ALSO how hard is it to replace a tie rod on my own and then taking it to get alighned?
