doobaruGT Posted January 18, 2012 Share Posted January 18, 2012 So...A few months ago I started noticing the trademark squeal of the Throw Out Bearing...or so I thought... Last weekend I drove home from helping my friend with a grill mod for his 2012 WRX and my clutch slipped twice while in gear. The clutch was completely in gear and it happened while accelerating. It was only a 400rpm fluctuation and lasted only a split second. This concerned my and I remembered about my TOB. However, the squealing is gone and while I'm sure it could use replaced, I'd like some input before I spend $1000 to tear down the tranny. Other useful info: it's an 05GT that has 132K (nearly all highway) and the clutch was done with a stage 1 exedy around 70K. It's also stage 2 and while it doesn't happen very often...sometimes I put the pedal to the floor...thoughts? Thanks guys! Updated parts list since original part-out here.

whitetiger Posted January 18, 2012 Share Posted January 18, 2012 your clutch is shot. when you get a new one, you will do a TOB as well. 2 birds, 1 stone, done. Link to comment Share on other sites More sharing options...
AZP Installs Posted January 18, 2012 Share Posted January 18, 2012 When the clutch was done did they use the Exedy throw out bearing? You only have 50k since the clutch was done so I would be hesitant to say do the clutch again. However if you dont fix the issue, the throw out bearing could destroy your snout. It does sound like the bearing and clutch are wearing though. I would have it looked at by a knowledgeable shop. -Jake http://www.pbase.com/paisan/image/91072632.jpg http://www.pbase.com/paisan/image/133406601.jpg http://upload.pbase.com/image/137566671.jpg Call directly for your best Whiteline Price! | We also carry almost every manufacturer now, so before you buy parts call us.

doobaruGT Posted January 18, 2012 Author Share Posted January 18, 2012 Thanks for the input guys...I know what a clutch slip feels like on a bad clutch and this was not the same. It was not a gradual rev as a direct result of my acceleration input (like a usual clutch slip would be), Instead, it was like there was a quick acceleration without my foot increasing the gas. I've had some idle oscillation issues recently too. To further support my thought that the clutch is still good, It's still very strong and I ddi some pulls that were more than satisfactory... I'll look into the TOB and check the clutch when I pull it apart. Updated parts list since original part-out here. Original Full part-out of my LGT HERE!

doobaruGT Posted January 18, 2012 Author Share Posted January 18, 2012 I also might by a clutch kit JIC, better to replace it when it's all torn apart if it turns out to be a bad clutch, though I expect an Exedy to last longer than 60K Updated parts list since original part-out here.

doobaruGT Posted January 19, 2012 Author Share Posted January 19, 2012 Here's an update... Today while driving home I was coming up on my exit and I needed to change lanes. I change to the middle lane and accelerate lightly in 5th gear to get up to an open spot on the exit. My initial speed was about 55mph and I was heading towards 65 or so. To give you an idea of how long I had to merge, the exit was still a half mile up (the exit ramp is 3/4 mi long) and I was shooting for a spot about 300 feet away. When I accelerated I felt that strange "clutch slip" again. I say strange because my pressure on the gas was constant and the RPM's increased slightly and then dropped to the correct sync all within a split second. The part that's really strange is that from there I decided "if it's the clutch, I want to know for sure" so I decided to pull hard in my lower gears from my remaining mile home. I put the pedal to the floor and let 'er rip. As it turned out, my clutch gripped like a champ both on the gas and off. I continued the hard pulls at every opportunity and was unable to recreate the problem. So the question is, why would I get a slip from gingerly accelerating in a low torque gear like 5th, but be unable to recreate the problem in the next 60 seconds in my higher torque gears. I know it's difficult to convey what I felt on the forum, but I figured this may give you guys some harder data to help problem solve. I really only know basics of Tranny's.

whitetiger Posted January 19, 2012 Share Posted January 19, 2012 yes, the higher the gear, the more it will slip. 5 gear requires the most power to make the car accel. think about it. Link to comment Share on other sites More sharing options...
doobaruGT Posted January 19, 2012 Author Share Posted January 19, 2012 I guess that makes sense....crap....looks like I should start researching clutches:ohhh:. Any suggestions?

AZP Installs Posted February 5, 2012 Share Posted February 5, 2012 Just wondering if the Exedy TOB's are not very good in your experience? Thanks The Exedy ones are usually fine, however some places may pocket the TOB that came with the kit and re-use the stock one. Another thing we've seen to be an issue is a shop will fail to lube it up properly and this will result in premature TOB wear and/or snout wear. -mike http://www.pbase.com/paisan/image/91072632.jpghttp://www.pbase.com/paisan/image/141039922.jpg http://www.pbase.com/paisan/image/133406601.jpg http://upload.pbase.com/image/137566671.jpg 11+ Years Maintaining, Modifying and Educating TriState Subaru Enthusiasts.

JoeFromPA Posted February 5, 2012 Share Posted February 5, 2012 You need to test for clutch slip by going into 5th gear, preferably up hill, and flooring it at 2000rpms. If your clutch wants to slip, it'll slip then for sure. I've got 77k on my stock clutch, wife-driven, and she rarely rev matches on downshifts and usually likes to give it some good throttle during 1st gear take-offs while the clutch is still engaging. I usually do a 5th gear WOT pull on thehighway every few weeks. If it doesn't slip, then it's still good So far, it's still good! Link to comment Share on other sites More sharing options...
