rjnakata Posted February 10 Share Posted February 10 (edited) That new sound...01 GT Wagon 5MT 250K Now a new drive train related (not engine) fast high frequency "chipping" when accelerating from standstill, occurring in sync with the acceleration...up to about 30 mph. Ideas? Help! TIA Edited February 10 by rjnakata Link to comment Share on other sites More sharing options...
silverton Posted February 10 Share Posted February 10 I know this is gonna sound crazy but..... muffler bearings. In all seriousness, the internals of the muffler are likely falling apart. had it happen on my third gen almost immediately after getting the transmission rebuilt. and I hear it all the time on 2nd, 3rd, and 4th gen foresters. I don't know why the foresters so much. 1 Link to comment Share on other sites More sharing options...

I did change the fluid in the turn signals and it cured a bad clicking sound whenever I used them...haha The chirping sound seems to be tied to the transmission - ie faster acceleration / faster chirping. But up to about 30 mph. It does seem to come from the back. I'll keep an ear out for the muffler. It comes and goes now... As always thanks for your insight.

silverton Posted February 14 Share Posted February 14 Yeah the sound I heard from mine seemed to be coming from the front/middle too, does it happen in neutral or only while in gear? you do have a manual so it could be your throwout or pilot bearings. 1 Link to comment Share on other sites More sharing options...

Happens while accelerating IN GEAR, but disappears with clutch depressed... Sounds kind of like a propeller scraping on something...more rpms = faster spinning of the propeller.. It does come from the front somewhere... Link to comment Share on other sites More sharing options...
KZJonny Posted February 15 Share Posted February 15 Start of terminal failure of a bearing in the bellhousing? Link to comment Share on other sites More sharing options...

KZJonny Posted February 15 Share Posted February 15 (edited) That could be the pilot bearing. Maybe the propshaft on the way out? Sorry dude, this is just ideas about what to have a look at. Diagnosis of rando noises via the internet isn’t exactly a fine science. Clutch components were replaced with the transmission? 100k (miles?) is still about the life of some of those parts if driven….. enthusiastically.

Diagnosis of rando noises via the internet isn’t exactly a fine science. Appreciate the time. The driveshaft was replaced about 75K ago. The noise happens when the clutch is NOT depressed so not thinking it's the pilot... So I'm at a loss. Sometimes sounds like a cricket chirping that gets more excited as I accelerate....but most of the time nothing. Link to comment Share on other sites More sharing options...
doublechaz Posted February 16 Share Posted February 16 Perhaps a broken spring clip on the throwout. Sometimes it sits happy, others the missing spring clip lets it touch the fingers? Can you get the car lifted on frame blocks enough to have all four wheels off the ground? If so, you could try to get it to make the noise while you can climb around and check things. You might be able to see something through the clutch arm hole with the boot pulled off, and there is an inspection hole opposite of the clutch arm. Don't get crushed or rip any of your parts off working around moving parts. Link to comment Share on other sites More sharing options...

Honestly that sounds like it...ie like a propeller blade scraping lightly against metal.. Driving in the air,..and crawling under does sound a bit hairy.... Thanks all.

silverton Posted February 16 Share Posted February 16 scraping metal and a helicopter sound... almost definitely the throwout against the pressure plate 1 Link to comment Share on other sites More sharing options...
doublechaz Posted February 17 Share Posted February 17 A frame lift or those parallel lifts are best. It can be a real deal to do this without those. If in doubt, don't do it. 1 Link to comment Share on other sites More sharing options...

Would that at all be related to a single transmission related clunk heard when starting from standstill? Sounds like another bushing is worn..

Paycheck Posted March 13 Share Posted March 13 Hey gang. I might have the same or similar issue and was looking for some ideas. Went for a spin with a buddy last night and he thinks it might be the transfer case. We'll lift it up next week and have a look. I also just uploaded a you tube video so you folks can hear it, but it won't be public until tomorrow. Will reply again once it's available. $$$ Link to comment Share on other sites More sharing options...
Paycheck Posted March 14 Share Posted March 14 Here's the video. Whining noise. Pitch increases with speed, as opposed to acceleration. This is why I think it's gear / diff / output shaft related as opposed to clutch related. Thoughts? $$$ Link to comment Share on other sites More sharing options...
