well, i priced the actuators from the dealer & they weren't that bad. they are about $76 each. i'll definitely buy the driver's one & then test out the passenger one in time.

 

well, got the truck back to the house today & just payed a little more attention. looks like the noise from the actuator is coming from the left rear door. appears that the driver's door is working fine. but the passenger front & rear doors are not working at all or making noise.
