How do you install headlamp assembly on a 2000 Lexus RX300?

Answer 1

What I found is to take off bottom part of the Grill which is held on by Philips head screws, easy to get to. Then using a 10mm socket unbolt the top bolt holding on the headlamp assembly. Now the tricky part. There are 2 10mm nuts holding on the headlamp assembly inside the fender. You must unbolt the wheel well plastic liners, but not all the way. Only take off the bottom 3 10mm screws from under the bumper and the 2 10 mm screws inside the front portion of the wheelwell. Then using a small Phillips head screw driver unscrew the first 2 screws inside the lip of the wheelwell. This should allow you to pull back the liner and reach inside the wheelwell and unbolt the headlight assembly. The top nut use a short extension on the socket and the bottom nut use a long extesion. And the headlight assembly should tilt up slightly and pull out enough to remove the wiring hookups. Remember you will need to save the nuts you take off because they do not come with the new assembly. Also install the black trim piece in the headlamp prior to installing. Total time 2 hours for 2 headlamps.
