The other day i hopped in my truck backed out the driveway and when i started down the road and i got a loud noise that sounded like a stick in bicycle spokes i called my buddy he said it was probably my hub assembly so i picked up a timken one from autozone replace it noise went away for 2 days then it came back i put the truck in 4wd noise went away put it back in 2wd and it only made the noise a every 20 seconds or so any ideas?

 

im not sure, my brother had vacuum problems one time on his truck, and it was causing it to engage/disengage wile driving, i dont know on them years how the hubs work, if there live or they lock in/out

 

anybody else

 

or ur CV shaft is shot? they will make nine kinds of noises if bad
