AWD light is on, had a bad front axle bearing, changed that, checked fuse 30-okay. bad springs and shocks in the rear, changed those. I don't know if that sensor in the differential could be the issue. i ordered a new one but not here yet, any advice if this sensor doesn't work?

Hi,

Chances are the differential clutch pressure actuator is bad. Since you worked on the rear, something may have been disconnected or damaged with the wiring, so check that.

If you look at the attachments below, they provide the diagnostics for an AWD light always on. Take a look through them and let me know if you are comfortable performing them.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
