Cant adjust passenger side headlight...

Well after replacing the driver side headlight (the entire unit) I noticed that the passenger side headlight is not alligned properly. When I went to adjust the headlight, the adjusting nobs (dont know what they are technically called) wont budge at all.

What could I use to loosen them? I was thinking WD-40??


Btw I am working on a 1996 GMC Jimmy 4 door if that matters.


Edit: Would I be better off replacing the passenger side headlight unit since the drivers side is a little bit brighter?

Please if anyone can also tell me, how to align the headlights. I mistakenly adjusted mine quite high,:screwy: but I can't find any stats on how to align the lights. It is a 98 Jimmy.

Hi Keck,
The easiest way I have found to adjust headlights is to use the back wall of a garage. pull your jimmy right up to the wall and use masking tape to place an + on the wall that represents the center of your headlights.
Back the jimmy up 25 feet(must be level) and turn on the headlights. Low beam should hit 2 inches low and 2 inches to the right(both sides to the right) of the tape +. switch to high beam and the light should hit just below and dead center of the + ,if not use the adjusting screws ( one center top and one center inside of the headlight.
any questions PM me and I will try to explain better.
