OT Please Help Truck headlight ? how to adjust

Brad in WI · Aug 12, 2008

I have a 1998 GMC Sierra and I need to lower the headlights down some. I can not see how to adjust them though. I found two 5MM posts that when loosened remove the entire headlamp assembly. I have already looked in the vehicle manual and it gives no idea how to adjust the lamps. I have the two lamps on each side composite style. Thanks

the headlamp adjusters are accessable from the top of the core support straight down. they are either a torx or 4mm socket. if they are torx you need a real long torx driver.

Thanks I thought that was them but all four adjusters were rusted solid. had to take it all apart and work them loose. now waiting for less light to fine adjust them. LOL
