great! More AX5 Clutch problems!!!!! hooray for internal clutch slave cylinders!

so i just replaced my clutch and slave cylinder a little while back and now... i'm having problems AGAIN

It did great for the first month or so...

Now, after driving for a couple days my clutch has almost no pressure. It feels like it's almost out of fluid, has air in the lines, or SOMETHING.

Check the fluid..... still about full (i'm bad about filling to the line exactly but it looks to be about the same level as I left it when i last bled the system and filled the resevoir).

I loosen up the bleeder screw at the bellhousing and let the fluid run out.... gravity pulls it out and as it does, I am refilling the resevoir.

After i let about 2 resevoirs worth of fluid run out i run around the jeep, dive under it, and tighten up the bleeder screw.

Then i top off the fluid in the resevoir....

She's good to go for a couple days... then it's at it again... low pedal, crappy pressure.... not good.

REPEAT

good for a couple/few days... then REPEAT.



has anyone ever had a problem like this before? I don't see any leaks... I don't think it's leaking... but it could be a slow leak i suppose..... BUT even with a slow leak, the clutch should work fine if there is fluid in the resevoir.... or at least when my old clutch slave cylinder was leaking that was the case.

What do you guys with experience in this area think?

I hate to think that I have to drop the tranny/tcase AGAIN... though my rear main seal, which i replaced when i did the clutch, appears to be leaking kinda hard to tell since i have so many oil leaks (dipstick tube mainly, but it's bad)


what are your opinions guys?

-Erik <---- really really sick of bleeding the clutch every few days

Try bleeding it again with someone pumping the pedal. I know gravity bleeding should work but I think you need some pressure there to force the air out. I know internal slave sucks!!!

I'll give that a try tomorrow at work.... don't have anyone where i'm staying while on this job site which is why i've relied on gravity bleeding it so far. HOPEFULLY that will do the trick, but i'm doubtful since THEORETICALLY, gravity bleeding should do the trick... or so i thought.

Probably your clutch MASTER cylinder...if the seals go bad in it, it will suck air in through the seals, but the fluid level in the reservoir will not change much, if at all. MUCH easier fix than slave!!

Usually if you're not losing fluid in the reservoir it's the master cylinder, if you are losing fluid, it's either a leaking line or a bad slave cylinder.

Good Luck!!

And two motor swaps, not to mention a new rig.
