When driving straight or turn to the left, howling noise coming from left front end. This is a 1/2 ton 4 wheel drive. Turn left noise stops. I jacked it up and spun wheel, makes little noise, grabbed tire and tried to see if any play, there was none, so my first thought of it being a wheel bearing may not be the problem, I would think I would hear grinding and wheel would be loose. Any ideas?
also what is the correct engine idle speed? There is a vibration at idle, especially in gear and A/C unit comes on, but rev it up about 100 rpm and it quits.
have the same problem?
