I had the bearing on one of my idler pulleys self destruct while going down the highway. Chewed up the metal behind hte bracket a bit. nothing that would prevent a quick fix. Made a mess out of the belt when it went.

New pully and belt and it was good to go again.

get a breaker bar/wrench and rotate the pulley up until you can slide the belt off the ideler pulley (a smooth one without groves). Once you have slid the belt off you rotate the pulley back down until there is no longer and force trying to rotate it. Reinstalling the belt is the opposite procedure

slight bit of damage to mounting post

bearing spacer old one on the bottom had the inner race stuck to it. new one is quite a bit smaller but it works.

and done
I just had this go out on me. I wonder if you could help me. Where did you get the part? Part number? I went to O'Reilly and got something similar , but it doesn't appear to be right and when I put it in, there is play front to back on the bolt of about a quarter inch and it clearly doesn't look like yours or the old one in the middle as the cavity on the one I got is much smaller. Please help if you can. Thank you, ken

Autozone and napa stock these parts, not sure if there is one near you. You can usually check online inventory.

Thanks, I ended up going to Jeep and picked up a pricey one for $41. I was antsy because I'm going out of town in about 30min. It came with the spacer, bolt, and washer. I did try autozone and they didn't have any, but I should've thought about napa... install was cake. Thanks!

Mine's been squeeling for weeks now and my voltage meter drops to zero and I get check battery on the VIC...

Is this the problem?

What happens when it goes out?

Yours just may be a VERY loose belt. My pulley made a very loud CLACKY CLACKY CLACKY when it puked its bearings. I got, maybe twenty minutes of light driving before it seized completely. Then it was all squeels. Barely made it to the garage before it threw the belt off.

Pretty lucky if you ask me.

Change your belt.

I've checked the belt and it looks good and is also tight.

I get a crazy chirping/squeeling sound usually on cold start up and then it'll stop and everything's fine after some driving.

Similar thing happen to me. Got up early to go wheeling, heard a squeaking. Thought it might just cause it was a really cold morning. Stopped to get gas, popped to the hood to check it out since the squeak never got better and the belt popped off right afterwards. So I pushed it back on, limped the Jeep to a parking spot, had a buddy come pick me and take me to the parts store. Bought a new one and replaced it right there, no problem.

So yea, they can just go out with no warning.

Idler pulley parts

My idler pulleys each have a bushing that inserts into the outside, but nothing between the pulley bearings and the engine. I lost a top idler and it's mounting bolt, and broke the belt.
This parts site tells me I should have a washer (2) behind the top idler and a spacer (9) behind the bottom idler. And they ain't cheap for washers: http://www.factorychryslerparts.com/...chString=idler

Is this correct? I've gotten along all this time without these, (yeah I know, lost pulley, broken belt) and wonder if I should have them in my car. Belt seemed aligned fine without.
