ZJ Headlight aiming

I know this has been discussed numerous times already, but I've searched and searched the forum for an answer with no luck. Can someone show me (ideally with a photo or two) where the headlight adjustment screws are on a ZJ? Thanks.

open the hood, look at the back and side the headlight housing. There are 2 things to turn, one for vertical and one for horizontal. Both use a 6mm allen head. Its the only thing there that uses an allen.

that reminds me, I need to adjust mine..

Like he said above they are right there on top of the headlights. The top of the screw looks like a star..

Spray WD40 in the adjuster holes and work the adjuster back and forth to loosen it up. The plastic gears can strip out easy.

Allen on my '93

93 red ZJ 190k 4.0. Spent more money than I should have ...

Isn't red the only color a vehicle should be?
If at first you don't succeed, use more speed.

Even Haynes says allen for ALL ZJ's.

Outer screw-verticle

Inner screw-horizontal

They are set below the sheet metal over the headlights. Look down and you'll see them.


I think the proper aiming is at 25ft the beam should be at the horizontal center line(floor to center of headlight) and verticle center line(center of jeep to center of headlight) of each head light.

This should be done on a flat/level surface and a wall and Haynes says a 1/2 full gas tank(that I don't think matters too much).

Can you fit a torx in a hex? Yes.

You can look and see whether they are hex or torx. Its a big difference. Mine are definitely hex.

And I love haynes. Its great for the "back yard" mechanic. Granted they don't go as deep as some but they work.
To each his own. They don't work for you.


And by the way, haynes has correct info.

Hmmmm...

That looks nothing like ours. Yours is a different body style. That doesn't even look factory. Is that looking down from above?

Ours have a large plastic disc ontop that is clearly a hex.
