Thank you for using just answer.My name is XXXXX XXXXX i will assist you today.
I am sending you the information you will need for aiming and adjustment of the headlights. Click on the link below for the info.
that's not correct--my light unit is held in place by three threaded pins that have an adjustable plastic collar on each--the pins are secured by two "L" shaped plates that slide down to secure the threaded pins--
inspection reveals nothing broken and the new bulb that I installed is seated securely in the socket
Sorry--do I need to do anything or will you transfer the question to another tech?
Take a look at the pic below
each headlamp assembly is held to the body of the truck by two vertical metal bars ,,, when you slide these bars up ,,this will release the headlamp assembly and you can remove it ,,, now looking at the back side of the headlamp assembly you will see that the outer metal bar holds two posts on the headlamp assembly,,, the top post is your adjustment screw for making the headlamp adjustment for up and down --so to move this headlamp up or down you can screw this post in and out ... the bottom post on that same side is for the adjustment of left and right ,,, screw this in and out to adjust the headlamp to the left and right ... most of the time your adjustment is either to high or to low ,,, so you do not have to remove the headlamp to adjust this ,,,just use a pliers or a dike to grab on to the top post adjustment and turn it in and out to adjust the headlamp up and down
any more info just ask , we can go back and forth on this page
understand--the top post is very difficult to move--which way should I move it to raise the beam? understand that the bottom outside post is lateral movement--same question--which way to I move it--(am I really moving the plastic collar that is on the threaded posts?)
the top upper post that the outer metal bar holds in place , is for the up and down , the post should have a plastic insert that metal bar grabs on to ,,, then out of the center of the plastic insert is a metal threaded post,,, the threaded metal post is what you turn to make the headlamp go up and down , with a dike or pliers ,,and the plastic insert should not move while you turn this ,,,, turn the threaded post inward ( tighten ) to make the headlamp go down ,,,turn the metal post outward ( unscrew ) to make the headlamp go up
the bottom inward post( toward the radiator ) ,( that you cant even get to unless you remove the headlamp ) is for the left and right ,, turning it inward makes it go right ,,, and turning it outward makes the headlamp go left
