ajp Posted April 13, 2013 Share Posted April 13, 2013 (edited) So, I suspect the throwout bearing might be going as it is hard to downshift from 4th to 3rd unless the rpms and speed is just right - this has been going on for about 3000+miles. Now, I have an oil leak (getting under car in a minute to figure that out) and all of a sudden car is making this high pitch whistle/whine noise, but only in 4th, and only when accelerating, if I let off the gas for a 1/4 second noise goes away, comes back when I push the gas. no noise at high rpms in other gears or neutral. Is this the TO bearing, or a transmission issue? I always appreciate the help from USMB. Thanks folks! Edited April 13, 2013 by ajp Quote Link to comment Share on other sites More sharing options...
mikaleda Posted April 13, 2013 Share Posted April 13, 2013 Throw out bearing is only in use with the clutch depressed so no on the TO. it sounds like you have worn syncros and possibly a failing input shaft bearing. 1 Quote Link to comment Share on other sites More sharing options...
ford'ssubaru's Posted April 13, 2013 Share Posted April 13, 2013 Agree, with the above. Now my only real question is the downshifting issue. That is a synchro issue and the whining is like Subaru Nut said the input shaft. If you have it apart replace the input shaft bearing anyhow....Cheers.

l75eya Posted April 13, 2013 Share Posted April 13, 2013 Check that your gear oil isn't low. 2 Quote Link to comment Share on other sites More sharing options...
ajp Posted April 14, 2013 Author Share Posted April 14, 2013 yes gear oil was realy low. I am feeling a little dumb. had this car for 60K of the 240K thats on it, and the front gear oil has always been fine. it has been awhile since I last cheked it - with that tire there and all. hopefully that is it and I didn't kill this car that has been so good to me. 1 Quote Link to comment Share on other sites More sharing options...
l75eya Posted April 14, 2013 Share Posted April 14, 2013 That happened to my brother's Impreza. Gear oil was always fine. One day he noticed 5th gear was a little funky and was making a whistling noise. Gear oil was bone dry. Never any signs of a leak or anything.The transmission was alright but ever since then 5th gear has a dull constant whine though. 1 Quote Link to comment Share on other sites More sharing options...
ajp Posted April 14, 2013 Author Share Posted April 14, 2013 I hope I didn't fry it. planning on taking this car from CO to OR in a couple of weeks. Quote Link to comment Share on other sites More sharing options...
mikaleda Posted April 14, 2013 Share Posted April 14, 2013 You're probably okay, as long as the whine goes away and it starts shifting better (wich it should). Quote Link to comment Share on other sites More sharing options...
ajp Posted April 14, 2013 Author Share Posted April 14, 2013 the transmission took a quart and a half of gear oil. fella at the counter said that if gear oil eventually gets low, then it will allow a seal to dry out and then all the oil leaks out. no signs of a leak in mine. I'll report the findings as soon as I get a chance on the open road. thanks for the direction! Quote Link to comment Share on other sites More sharing options...
rdweninger Posted April 15, 2013 Share Posted April 15, 2013 Drain and Refill the Tranny Gear Oil... for sure. Clean the magnetic drain plug well. Replace the drain plug gasket (yes, there should be one). My brother bought an '83 a few weeks ago. I suggested he change ALL the fluids. When he drained the Rear Diff oil, only a few ounces drained out. The top fill plug was only finger tight... oil must have been leaking out there when rear end was spinning. Save our Subarus (SOS)... people! Lubrication is Good! 2 Quote Link to comment Share on other sites More sharing options...
im56seann Posted June 10, 2013 Share Posted June 10, 2013 So I've just noticed the exact same problem with my 2000 Outback. High pitched squealing sound while in 4th at high RPMs only (and also briefly while shifting between 5th and 4th). I haven't checked the gear oil yet. I was wondering what became of your car. Did topping up the gear oil fix the problem? Quote Link to comment Share on other sites More sharing options...
