I just changed the belt for the first time today, 65K kilometers (about 41K miles). When I got it off I realized it looked like new still, so it's my spare now. I also replaced the tensioner pulley because it was chirping. Very easy to do, but I found it easier with the air box removed. Barked the livin jeepers out of my knuckle taking that out. The pulley actually wasn't in bad shape but it has a small bit of wear around the bearing on one side. It'll do for a spare in the tool kit.

So I examined the rest of the pulleys and saw the steering pump pulley has a crack. I tried to get one from Napa since they had the tensioner pulley and belt, but they can't get it, so I ordered one from the stealer.

This winter the steering pump had been squealing for a few seconds on startup, but I did what was recommended in another thread, and replaced the steering fluid, using a turkey baster, and it shut the heck up totally. Nice and quiet now.

This is such a great place to learn about Jeeps.

That's normal,all of our PS pullies has that crack.The new one will come with that same crack in it.

Oh.
Ok, well thanks! Won't hurt to have a spare one of those too, I guess.
Just out of curiosity, what's the crack for?
