Ok well in about a week I'm dropping my tranny to replace some bearing's I have some fairly loud bearing noise when I release the clutch and it starts making noise so that tells me it's the main-shaft, the counter shaft, or the diff. I know it's not the throw out bearing on the clutch because it doesn't make noise when the clutch is disengaged and since the main shaft is usually the culprit I'm going to guess it's that.

My question is while I'm in there is there anything I should replace other then the bearings and if so could you show me which parts? Car is an 04 with 90,000 miles on it doesn't leak a drop of oil and shifts smooth as butter just making noise now.

Replace the input shaft seal under the input shaft bearing, it's cheap and if it leaks it will ruin your clutch.

 

Do you have the part number? I can't find that or the input shaft bearing that sits in the case.

 

The bearing part number is 91002-PS0-003 and the main seal behind it is 91216-PL3-005.

 

Hey thanks a bunch man I was looking for it all day finally found it! Time to tear down hope I don't screw it up.
