Ok i have a 2000 chevy blazer 4wd 3 button setup. And recently i had my front brakes replaced they have been working fine but yesterday or so i started to hear like a thud noise coming from one of the tires i am pretty sure right front. Anyway it just sounds like a constant thud noise. I took it to wal-mart today where i bought my tires and had them check my tires for knots and balance them to see if that would help it did not. It sounds really bad around 40 or 45 miles a hour and i can feel it in my gas pedal. I think it is the wheel bearing but the guy at wal-mart said he thought it was the rotor but i just replaced the rotors around 4 months ago so i do not think it is that. Just let me know what you guys think
Thanks

 

just a thought.... might want to check the caliper bolts, they make a pretty nasty noise when they come loose or break. could be the hub also. check it to see if it is sloppy. What kind of noise does it make when you hit the brakes?

 

I really don't hear a noise when i brake i just hear it really bad when i press down on the gas pedal. I really doubt it is the caliper bolts because the guy i took it to replace the brakes he is really good about checking out those kind of things i am sure he would noticed if the bolts where bad but i will look into it. It is making the same kind of noise when i replaced the driver side hub assembly

Also does anyone know how much it would cost to take my blazer somewhere and have it done by a pro?

 

not sure what it would cost to take it to the shop to have the hub changed. i do all of my own stuff. prolly find a new hub on ebay cheaper than the parts store though. might want to check it out.

 

Well went and bought the new hub at the parts place 100 bucks for that then i took it to a shop and they dropped in the hub for 50 bucks and thankfully the noise went away

 

good deal... that wasn't bad on the labor...
