while im driving.. and near almost every gear low rpms i hear a thunk thunk thunk thunk sound.. (clutch released) does this mean my clutch is going bad? and needs replacing?

what are the symptoms of a clutch going bad?

Thanks in advance

 

A thunk thunk sound is definitely not good. Your post is twofold. I'll try to help as best I can.

Question One:
A sure way to tell if your clutch is bad is if you are in a higher gear than you should be, and you hear the engine tach up, but don't increase ground speed; like 5th gear at 20 MPH. If you hear the engine rev up, and you aren't gaining speed, the clutch is shot.

Question Two:
If the sound is consistent in its frequency, in every gear, I would lean toward something in the transmission/differential/planetaries.

Is the sound consistent at all speeds, based upon the engine RPM's? Try to give as much detail as possible.

Possibly a tire that has a tread separating? That makes a thunk thunk sound. Or is it a wop wop wop???

 

kinda like a grinding.. usually in the higher gears.. from 2-3 k rpm

i always thought the clutch as like.. slipping a little.. its like how you hold a crayon at the top and drag it along the paper like how it skips

 

good to know my clutch isnt shot..my car is at like 800 rpm's and 20 mph in 5th gear..and i know if i let go..itll sound like im about to stall :X

 

how high can u lift ur foot off the clutch b4 ur car stalls?....best way is to do what KOrn said in his first question. my car did that for a while, but i finally changed it..so niceeee
