My upper idler pulley is growling at low speed.(is this common?) It has a lot of play in it but I can not find the belt routing diagram any where. I first believed it was the Transfer case making the noise, But I have changed the fluid per the forum on the TC and Rear axle at 25K intervals. I found the problem with a scope (carefully).

Anyone replace the serpentine belt and 1 or 2 idler pulleys on a 04 x-type 3.0? Does anyone have the diagram or a link to one? My other option is to photograph it prior to repair. The Jag has only 53K miles. (I am the original owner)

Also, do I have to access the lower pulley by removing the wheel and inner fender well?

Any help would be appreciated.
