when i put in 4hi light flashes Tcase works but wheels don't pull

sounds like this part would help it. the actuator engages the front axle. also the connector may be loose or cracked to the actuator. or the actuator it self maybe out. also the transfer case uses a selector motor. it may also needd to be checked before blaming the axle actuator. u can see the driveshaft moving and the front axle won't move at all.

Does this actuator come with the wire harness?

no the wire harness s sold separately

Will this fit 07 (new body style) chevy silverado?

Yes this will fit all the way up to 2013 GM Trucks including Silverado Sierra

Will this work on a 04 yukon that is all time 4wd?

This is the front axle actuator that is activated by the 4WD button. It locks the front axle for full time 4WD high and low
