Tick tick tick tick.... from the tranny or bell housing?

I have a new noise to keep me company in my 94 XJ 4.0. It's a light ticking from the trans area, or maybe the bell housing, whenever I'm idling. It goes away under any kind of load.

Any quick ideas?

I had an XJ before ( 3 actually ) but non the less had the same issue. Mine turned out to be a cracked flex plate.

Loose flex plate bolts, or as mentioned, possibly a cracked flex plate.

Very common. Get them tightened up by removing them first, applying LocTite, and reinstalling them. There are 4 bolts. If you wait too long, the holes in the flexplate are going to get elongated. Then you get to pull the trans.

flex plate is basically the flywheel. The bolts refered to can be reached from the front side of the flexplate.

Pull your inspection cover, its the thin metal at the front of the bellhousing. Get a good flashlight and look up there. Check the bolts holding the flexplate on.. there should be mo slack in them.

Okay, flywheel I understand. Never heard it called a flexplate before. Is that a Cherokee thing?

Inspection plate...

Gotta be on the front of the bellhousing, I'm guessing. Probably pretty obvious once I get in there. Pull a few bolts, pop the plate off and I can see inside?


That adds up, too, because my stethoscope says it's more of a bell housing noise than a trans noise.


Hmmm. Did an image search on the Web and the first hit was one of our threads!


I'll try to get some pics while I'm at it. Might help the next guy.

Flywheel is for manual trans with a clutch bolted to it. Flexplate is a plate with a ring gear attached to it that bolts to a torque converter. Flexplates have been around since automatic transmissions have. Not just a Jeep thing.
