Replying to: rherna56 (Dec 12, 2006 4:58 am) Then this could be dragging brakes - rears will cause shake in the vehicle or out of round rear disc/parking brake drum or rear calipers sticking (common after a brake job - always replace rears as single plastic composite piston) - had them all before. Of course this assumes the tires are properly balanced and get a Force balance that the machine checks tire roundness and weight as well as the rim to rules that out. Then many other areas to look at and even the front end alignment can cause - should have been done after the ball joints! Then theres U-joints to check. Most good aligmnet shops can pinpoint the cause. |

I have a Humming Noise that happens when I get up to speed on the roads. I checked to see if it was the wheel bearings(on all 4 wheels), by moving the wheels to see if there was any play. There was NONE. I am now trying to figure out what else could be making that noise. If the road curves to the right while I'm driving, the noise stops. It is a 02 2 door, 2wd Blazer, 4.3L V-6. THIS IS ANNOYING AS HELL! This is the best way I can describe it.

Replying to: repairdog (Dec 22, 2006 3:06 am) I apologize for this one--> but I don't know how to see if my u-joints are bad, so I have not checked this out. Tranny fluid and rear diff fluid is what I'll check next. I'll have one of my friends help me check the rear pinion, and everything else mentioned, and I'll keep this posted and let you know where I stand. THANK YOU! |

Okay, I've narrowed down the humming noise to the front left wheel. I jacked up the truck and spun the wheel freely. I could tell then that this is where the noise is happening from. Then, I took off the wheel, removed the caliper and then spun the rotor and it still made this strong noise. I am guessing that I will have to replace the wheel bearing. I can't think of anything else that would cause this. Nothing in the engine, it's not the tires, and I'm pretty sure this would be the problem. Unfortunately, they only sell the bearing with the hub assembly together at any parts store for like $200. But on "Rockauto.com" I can buy the wheel bearing by itself for like 13 bucks and have someone press the new bearing into my stock hub.

SO.... I'm going to buy a wheel bearing/ hub assembly next week. One of my friends works at autozone, so he may be able to get me a 20% discount...which is good because after tax I'll only be paying $170, and it comes with a 1 yr' warrenty. My only question now is, is replacing the entire hub assemlbly managable or is this gonna be a pain? The bolts are not rusted so I hope this goes well....THANKS!
