4th gear manual transmission whine
Posted by SRS900S [Email] (more from SRS900S) on Sat, 11 Nov 2017 08:15:40
2008 manual transmission ~88K miles, fluid changed ~5K miles ago.
First became apparent yesterday on the way home from work, but looking back I think I heard it the day before but not as loud. I was driving up a long hill at a steady 55-60mph at ~2500-3000rpm. It was loud enough that I stopped twice to check my wheels/wheelwells. I initially thought it was noise from the turbo but eventually I noticed it only occurred in 4th, not while in neutral and not noticeably in any other gears at any rpm.
This morning I was able to drive around a little to test different gears and it is obvious in 4th even at low rpms and possibly very slightly in 3rd also. I am assuming at this point it is a bad bearing(s) internal in the transmission, but I will have my indy drain/fill the transmission again and look over the car. Anyone have any insight as to what I am looking to replacing? I assume the motor/trans will have to drop and do a tear-down on the trans. Is there a common bearing in the 3/4 gears that isn't in the other gears?
