hello i just noticed my car started shaking at about 50-70 mph . Feels like its the rear. Car seemed fined yesterday on my way back from work now i feel the problem , when i brake i feel like the back is vibrating . Im thinking wheel balance can anyone give me any hints ? checked tires for bumps and loose wheel lugs

Wheel weight flew off
Hit a pothole and dented rim - needs rebalance or new rim
loose lugs
wheel bearing
loose axle nut

My first thought would be wheel balance, where you lost a weight while driving home from work. There are several other possibilities, Tlyko I suggest you find an independent brake/alignment shop in your area! All these shops do is suspension work so they'll easily find your issue once on the rack...Gary

Sounds like you may have a stuck caliper.

Dented front rim, I hate NJ roads, I guess I need a new wheel. Felt like it was coming from the back.

Been there before. My dented front rim got exchanged for my full size spare a few years back
