Front end rebuilt 10k ago.

1. Front left end makes "popping" noise over potholes.I can also feel some sort of thud on the frame. Why?

2. Car ticks when running, sounds like it has to do with the belts more than anything internal. Why?

3. Car makes clicking noise when driving. CV joints maybe? Is it bad to drive a car with bad CV joints?

 

for number 2 does the ticking increase w/ rpms? if so i think its one or more of your lifters.
