Throw-out Bearing??

Yesterday while off-roading I hit a good sized rock with something under the front end. Immediately after that I started getting what sounds like a throw-out bearing noise when engaging/disengaging the clutch. Could hitting the rock cause a throw-out bearing to suddenly go out. What else could make the same type noise when depressing/releasing the clutch? I have about 68,000 miles on the TJ and still the original clutch. Thanks for any info.

Does that have an external slave mounted to the block or bellhousing? If so, you might have bent the fork so that it's holding the bearing crooked or off center. Just as much work as replacing the bearing, unfortunately. There isn't anything else I can think of.

His it hydraulid Jim, Although the cylinder is outside they usually work or don't.

Does it matter if it is in 4wd or not? What does it do in neutral with the clutch released?

Any symptoms other than noise?

It makes the same noise in or out of 4WD. It doesn't make a noise with the clutch fully depressed or released. A couple of times it has made a slight grind when shifting into low gear, but very slight.

I am betting dirt in the bellhousing, But I am not a pro. I had the dirt problem once before and took out the slave and sprayed water inside the hole then after it all drained I put it back together. It slipped a few times but has been great ever since.

Surely you've been under there looking for damage, right?

Looked and can't see any damage of any kind. Drove it to work this morning and aside from the noise, I notice a slight tic as I shift into a low gear.

Is there any hole that a chuck of that rock could have gone through, and is now getting hit slightly?

Like maybe through the hole for the fork?

I'm going to try and get it on a lift tomorrow and get a better look at it, but I didn't hit the rock very hard, then backed up and got aligned better and drove over the rock. It wasn't like a tooth jarring hit on the rock. I'll look for someplace something could have gotten into the clutch. Thanks for the idea.
