Transmission guru's, I've got a question for ya
Well, I put a new clutch in last night and this morning, it was exciting none the less...manhandling the tranny underneath it. Had a few snafu's but its in and running...but i am still having issues that i thought the clutch would fix.
I diagnosis it as a throw out bearing, metallic squeal while in gear and driving, disappearing when the clutch is in. The old throw out was definitely bad, noticeable squeal when you spin it in your hand when it was out.
My symptoms are: while driving (only able to be heard at slower speeds, but i am sure it is there all the time, just not noticeable over road and engine noise) there is a metallic light raspy squeal. It will go away in two situations, one is press in the clutch and you will here it spin to a stop, or shift into neutral with out the clutch and it stops.
This tells me two things, its not clutch specific because to go into N with out the clutch means I haven't disturbed the flywheel/pressure plate/throw out bearing geometry. It has to be a rotating assembly inside the tranny that while in gear rotates, but once in N does not, even if the driveshaft is rotating. I dont know trannys enough to know what parts are spinning, in every gear (even if not under load) until you slide into N. What ever it is that rotates would normally spin to a stop quietly (like a good bearing, no noise situation) BUT it also occurs when the clutch disengages the tranny from the engine.
i am stumped, and am figuring what ever it is its a tranny rebuild job, which is out of my realm of expertise. I'd just like to know what it might be so I can determine how pertinent it is to do.
SO...what spins in the tranny until neutral or clutch is engaged. Does the input shaft stay under load and spin from the driveshaft even after the clutch is in? I noticed some play in the input shaft, maybe a 1/16th - 3/32nds, but thought that might be normal since the pilot bearing would solid that up.
Its a AX5, in a 1999 SE that I just did a pilot bearing, diaphragm and pressure plate, and throw out bearing replacement in.
And all those other Latin and Greek phrases that mean don't mess with me, I am a bad ass that knows Latin and greek phrases!
