Why does every right turn or bump cause loud, annoying grinding sound in ac/heater?

SOURCE: i hit a bump on

Sounds like your left front wheel bearing is going bad. When you make a right turn, or compress the right front suspension over a bump, it forces the car to roll to the left. This loads the suspension on the left side, which will exaggerate a wheel bearing problem. Are you hearing the noise at all when travelling on the highway in a straight line? If so, it'd be either a grinding sound or a hollow humming noise. If you aren't, it may be that the bearing is just starting to go bad.

A quick test to see if the bearing is bad is to jack the car up at that corner, grab the wheel at the top and bottom, and shake it hard - if there is any movement or looseness, your bearing is shot. If there is none, it doesn't mean the bearing is fine, but it could be that it's just starting to go bad (which would be why you only hear it in turns and bumps, but not straight-line yet).

SOURCE: Popping and grinding noise coming from the right front tire.

it depends if you have 2WD or 4WD, probably either your CV joints, or your wheel bearing, also have your upper and lower ball joints looked at, durangos are bad for those going out. 4WD could have additional problems, like transfer case, front axle bent, and other 4WD probs. i had a similar problem and it was my wheel bearing. buy it offline, not at the parts store, it saved me $140. compared to O'riely Auto Parts.

SOURCE: Right front is making a loud thumping noise

either broked break pad or disk or poss wheel bearing is loose to check later jack up front and try and push wheel in and out at top and bottom if it wobbles badly bearing has colapsed
