Default 07 sti 6 speed leaking gear oil from bell housing

Hey Everyone.

I have an 04 wrx with an 07 sti 6 speed and as i got home the other day i noticed i was leaking some redline smurfblood from my tranny. I checked the axle seals and the rear part of the trans where the DS slides in and those seals were good.

Then i noticed it leaking from the front bottom section of the bellhousing, right at the front section on the bottom where you can look through and see the cluch cover. Also i took the rubber cover off the top of the clutch fork and noticed some gear oil on the clutch fork.

Anyone ever run into this issue. I believe its the input shaft bearing/seal.

Anyone ever have this problem and how much would it cost to replace?

thanks everyone

How does your pilot bearing look? Input shaft leaks like this are usually due to a failed pilot bearing.

Hey

Not sure because i haven't pulled the trans yet. I replaced the pilot bearing with a new one when i put my new ACT clutch in about 1500 miles ago, so it should be in good shape but who knows until i actually pull the trans and see.

Do you know how much something like this would cost to repair?

You need to fix it straight away. If the pilot bearing is not present or isn't keeping the input shaft stable, the front seal will leak.....but other really bad things could happen if you don't take care of that situation asap. Just play it safe and don't wait to fix it. I would think front seal job would run around $800??

Hey Andrew

Does the 07 sti 6 speed need to be split open to repair the i/s seal/bearing?

Thanks

Default front seal

If you r in a pinch, I've replaced the front seal with some self tapping screws a chissel and a slide hamer with only removing the 4 10mm bolts that hold the guide. We did one in a winter rally..no time to do a teardown.
