How do you change the low-beam light bulb on Subaru Tribeca? Cant get the headlight assembly out. Have taken the two screws out, but something else holding lower corner.

I just had to do this and learned the hard way.

First take the battery out.
Second remove the plastic cap covering the low beam bulb
Thirdly there are 2 screws holding a wire tension spring against the bulb. Losen the screw towards the outside of the car (Don't touch the screw closest to the engin).

Once you do this, the bulb will come out and you can replace it.

Be aware that the bulb assembly is in a hard-to-reach area and some flexibility is required. Once the battery is removed you will be able to see/reach the plastic cap and housing covering the low-beam bulb and bulb cavity. On my 2008 Tribeca, there is one screw at the top of the plastic cap. Loosen but do not completely remove the screw. As you loosen pull on the cap and it should come completely off. You will now see the bulb and the wire mechanism, anchored by two screws, that holds the bulb in place. Take note how the wire mechanism is positioned to hold bulb in place. As mentioned in the earlier post, slowly loosen the screw that is closest to the outside of the car. Do not loosen the other screw. As you loosen the screw the wire mechanism should also loosen and swing away, which allows you to remove bulb. Replace bulb and reverse process. Also do not touch new bulb with bare fingers. The oil from your skin can cause a hot spot that can lead to early bulb burnout. I used basic kitchen rubber gloves.
