So today i was coasting down a hill and decided to turn off my engine and just listen to my drivetrain. Sure enough there was something quiet enough to go unnoticed with the engine on. It was a thump that had rhythm with how fast i was going. Is this a wheel bearing going bad? or something else?

 

i hope your rig is a 5 spd, otherwise you can damage your auto tranny if the engine aint running to pump the tranny fluid. Or atleast thats what i'm told.

 

yea its a 5 spd (take a look at my sig eheh )

but thanks for looking out man

 

Could be a CV shaft. Should clunk once/wheel rotation to give you an idea of the rythme of a bad CV. If turning aggravates it, it would be the outer CV, if not, then the inner. Check the boots. If a torn boot corresponds to the right CV joint (given the aforementioned criteria), then you've likely found the culprit.

Could also be your roommate on top of your ex in the back. Check the back.

 

You hit the nail on the head, i kicked them out and the sound was gone!!

 

both cv boots are fine, maybe a warped rotor?
