problem with rear left wheel
 

the rear left wheel of my car (94 mazda protege) seems to have a lot of negative camber. i don't know if theres something wrong with the alignment or the suspension. the rear left suspension makes clunking noises when going over bumps. does anybody know if its just the alignment that is off?

Check the upper and lower strut bushings

probably one of the easiest things u can do is while the car is partially jacked up from that corner, grab onto the wheel/tire and give it a good shake. it should be pretty much more or less solid, but if there is any play, then u know u got some issues. like suggested above, arms, bushings, and even wheel bearing can cause that. even something like a dead strut could affect it.
