how long can i go before i replace the input shaft bearings (b18c1 w/ ls tranny)? its been about 3 months now since it started making the noise

 

the longer you wait the more it can chew up inside the case. just imagine the the shaft moving around and gears not lining up properly and also the clutch disc can also become uncentered and chew up the clutch too.

 

well i was planning on replacing the clutch anyways while the trans was out. but hopefully i can get the money in a month or so to do it. the sound is so annoying lol
