Grinding Sound on Front Driver's Side When Turning Right
 

Beginning last week I replaced the rotors, calipers and pads all the way around on my 2011 Durango Crew. I started with the rear wheels and when I finished with them I performed the brake pad bedding procedure. The next day I started on the front drivers side and when I took the wheel off I noticed the outer CV boot was partly torn by the band clamp on the CV axle. The grease that leaked out was pitch black and looked fresh. So I suspected that performing the brake bedding procedure (speeding up then aggressively braking 10 times in succession) on the new rear rotors/pads might have caused the tear in the front CV boot (it's 9 years old). So when I was finished with the front brakes I ordered a new CV axle and wheel hub (since it will already be apart). While waiting for the CV axle to arrive, I had to drive the vehicle a short distance but I didn't want to perform the bedding procedure (aggressive braking) on the front brakes until I replaced the CV axle. So I decided to brake as little as possible. When I pulled out of the driveway I turned the steering wheel to the right, I heard a sound on the front drivers side. It didn't sound like clicking, more of a grinding sound. I suspected this was caused by the CV axle, not the new rotor and caliper. I drove carefully and parked it in the garage when I got home. The new CV axle and wheel hub parts arrived this week on Tuesday. So I installed the parts over 3 days and then test drive it today. When I test drove the vehicle, I heard a distinct grinding sound when making a right turn. I am not sure it is the same exact sound I heard after installing the new rotor and caliper. However when driving straight or turning left there is no sound. Since I replaced multiple new parts (rotor, caliper, pads, dust shield, wheel hub and CV axle), I am wondering what is causing this sound? Is it the rotor or CV axle? I am suspecting the rotor or caliper but I am not sure. Does anyone have any ideas?

From previous experience, and a guess, there is a dust shield. (thin tinny looking thing behind rotor) i have had this bend slightly before and rub against rotor. does cause a tinny grinding noise and louder when turning. they arent too thick and can bend out of line if you bump a tire or even lean on it.

not saying thats your problem, but have a look and make sure the dust shield has enough clearance from rotor and bend it by hand a little more away.

Hi Lemdog, thanks for responding. Its been a month or so now and this problem is still occurring. Although now the grinding sound is less noticeable on hard right turns. On small right turns there is no sound. I don't think a bent dust shield is the cause of my problem. When I replaced the CV axels I also replaced the dust shields. These mount on the knuckle parallel to the rotor. So when you steer, the knuckle and everything mounted on it (rotor, caliper, dust shield) move together as one unit. If the dust shield was bent and contacting the rotor, the sound would be constant, not just when you turn.

Thanks for your input.

no problem.

just a guess. good luck hunting down mysterious noise.
