My axel unlocked light is solid but, my front/rear light is flashing at the same time. Anyone have solution or reason why?

did it just start doing that, or its been doing it since you got it?

I'd check the sensors/magnets. Gotta pull the diff covers off, a great time to swap fluid too.

A professional grade scan tool would be able to pull codes out of the Final Drive Control Module and get you pointed in the right direction. Most good repair shops will scan for codes free of charge and then charge for diagnostic time if you want to pursue a solution.

You can also check your 50 pin sway bar and axle connectors for water intrusion, carefully clean them and apply dielectric grease. Bad connections are a common cause of blinking lights.
