popping noise

[Lowpros24]

Well I'm pretty sure my rack and pinion is starting to go.
when in park or not in motion, and i move my steering wheel
from side to side, i keep hearing a popping noise.
i havent gotten underneath yet, but looking through my rims
i can see that the rack and pinion boot is hitting
the frame, whitch i think is causing the popping noise
Im hoping its not anything to major, but it might still need to be replaced
more info when i get underneath and look.
BIG BUMMER!!!!
