Sound appears to be coming from the top of the shock area.
TSB 03-003-07 may relate to your vehicle:
Squeal-Like Sound From Front Axle Pinion Gear Flange And Seal
This bulletin involves the replacement of the front axle pinion gear flange slinger and seal.
2007 (JK) Wrangler
The customer may experience a squeal-like sound from the front axle. The sound will
increase or decrease with vehicle speed. The sound may be more noticeable at low
vehicle and engine speeds. This condition may be due to an interference between the front
axle pinion gear seal and the pinion gear flange oil slinger.
