Didn't have much luck using the search and I know there has to be a walkthough floating around on here. Going to smoke them next weekend so any help would be huge.

 

I actually had to replace one of them (it's quite the ordeal, since they aren't meant to be replaced, being LEDs), and turns out that there's a nut on the back that is an absolute hassle to get to, but you take that off, slide the whole thing forward a bit (not that easy), and push it out.

FWIW, ice buildup this past winter ripped the wires out of the back of one of my rear side markers, so that's how I found all of this out.

 

Ok, so you just have to remove the fender liner and the bolt will be right there?

 

I didn't even have to take out the fender liner, but then again, the first owner of my box hacked up the front and rear fenders pretty good, so your results may vary.

Either way, it's not /that/ hard to get at. Get the back of the car on ramps, and I'm pretty certain it's a 12mm nut-- a wrench will work better than a ratchet, though it will be slow until you can move the nut by hand.

 

the 6 bolts around the top of the bumper and in the wheel wells give you better access to it, take them off then the bumper lays back on the bottom supports...

Took mine off in 05, havnt seen them since...
