So I have a 2005 6 cylinder jeep wrangler, 2 weeks ago I got my front tires replaced because there was intense shaking going on when I hit 50-55 mph. I brought the jeep to PepBoys, they replaced the tires and said the tyrods were fine, and that it must me the tires. The shaking is gone, but when I hit a dip on the road I hear a grinding/rubbing noise. Anyone know what it might be? No death wobble? Thank you for your time!
