My XJ broke in holiday traffic

Last night while doing some Christmas shopping, I heard a huge noise from under the hood of my Jeep. It would go away if I revved the engine and return at idle.

Since I was in the middle of holiday traffic I drove on a few miles before I checked it.

When I opened the hood I found the idler pulley had spit out its bearings.

The thing I found most interesting was that there was no warning. There was no squeak or roar before the bearing separated. I have heard others squeak for years without failure.

So I am now recommending that this part be changed as a matter of preventative maintenance. Luckily I was able to drive mine to the perts store and them back to the shop. I would hate to have been stranded in holiday traffic if the belt had slipped off.

See my post on http://induprod.blogspot.com/ for a special holiday offer.

Hi, the EXACT same thing JUST happened to my Jeep Cherokee 4x4. A horrible sound just started one morning and I traced it to the idler pulley wobbling. Unfortunately I'm having an impossible time finding a replacement idler pulley bearing. Pep Boys wants me to wait 5 days for it to ship but this is my only vehicle and I need to commute to work. And I'm also afraid to drive it around and have the belt slip off. Where did you find your part? Thanks sooo much!

How much did it cost to fix? Was it a loud rattling sound? We had a loud rattling sound then the serpentine belt broke. Any advise would be good

$17 for a new idler pulley. Loud rattle then breaking belt is often the AC compressor failing.
