About 6 months after the clutch set was put in the SUBARU, and the pedal never feeling “fine” since - pressure plate? Clutch fork? Slave + master? Who knows.
Well now add this to the list - classic chirping noise, until you press the clutch pedal in.
However, judging by the fact that it’s new and the fact that the chirping noise happens occasionally, not always, and even at speed while in gear upto highway speeds I’m having my doubts about it being the TOB.
Any checks I can do to narrow down the issue?
I try to push in the clutch fork manually to no avail, too much pressure on it, however if the chirping is happening and I give driver-to-passenger directional movement to the fork, the noise either comes back or goes away depending on the location/angle of the fork.

Who cares, you have to remove the trans to fix either one.

Yeh but I’d rather not split the housing if I don’t have two.
John - any actual tests for input shaft? I though TOB not supposed to make noise at speed or be always chirping not occasionally or once the car is warm?

Was the noise always there from the start or it slowly kreeped up, starting out as a faint noise and then becoming very loud, to the point where you can hear it while driving, with exhaust?

my honda had the same thing. it was the TOB the lead to the springs in the clutch disk vibrating loose and jamming into the pressure plate. I drove it home 5 miles like that holding the car in first gear lol

TOB if it goes away when you push the clutch in.

OE five speed input bearings are beefy, dowel located in the case halves, Timken needle roller. If that was going bad, you’d also have a nasty gear whine from the gearbox as the tooth profiles moved away from their roots(I.shaft and P. shaft distorting), on top of a big leak from the IS seal. I’ve rebuilt a shit ton of those boxes and have never had a bad input bearing in any one of them.
TOB. Five speeds are cake to drop. Even my skinny ass can bench one of those gearboxes. Soak the nuts 'n bolts underneath for a day, you can have it in/out in 4-5 hours easy. It’s not a turbo, hardly anything to remove from the car.
Personally I’d just leave the fucker till it starts to go bad…

Thank you Adam.
As usual no Tech thread is completely answered until you chime in :lol :bowdown
What are the signs of it going south(er) more so than just chirping now?
