i have a 98 blazer and sometimes when i am passing another car the front right tire hums like i am driving over a rumble strip. if i stop or slow down and go into 4wd the noise stops. what do you think? is it something i can fix easily myself?

 

sounds like its the front wheel bearing needs to be replaced you might want to take it to be looked at and have the garage do a front end check if there is a munroe muffler shop they do this free of charge..

 

If the noise gets louder with more speed and quieter with a right hand turn, it probably is the right front wheel bearing.

 

thanks, i will bring it in, i am not sure i want to try to do the bearing myself
