Fender liner and front spoiler cover replacement

My guess is that, despite the drain hole, Toyota figured too much water (maybe salt, too) was entering through that part of the floor pan. Otherwise, and unless you need it to help anchor the fender liner, the extension pad seems optional.

 

The wheel well liner, and the spat at the bottom edge, and plastic ahead of it, you might as well treat as a single piece. I think Toyota actuall does. There's 3 bolts going through the spat, that clamp together the front piece and wheel well piece. On the inside there's a piece of flat bar and square weld nuts, for the 3 bolts. At least in my locale, those 3 bolts and the weld nuts were in a rusty marriage that's impossible to undo. Also, at the rear of the wheel well there's a screwing going into a plastic insert, that I think you pretty much have to destroy to remove. Oh, and on the side of the wheel well, around 2 oclock as you're facing the passenger side wheel well, there's a fastner with a slot in the cap: that cap needs to be turned 90 degrees to release.

The front piece with the zip tie, just track down the missing fastener, for starters. That said, that piece tends to take a beating from concrete wheel stops. It's low, and the engineers in their brilliance designed it like a barbed hook: the piece rides up and over the concrete curb stop before the wheels contact it, with a great scraaaape. Then when you back out the aforementioned brilliant design snags royally, tears itself half apart. Long story short, you may need to mend some fracturers at the lower edge: fiberglass mesh and 2-part epoxy on the inside is pretty good for that.

 

The front spoiler is easily removable, without even raising the car: one row of bolts (screwing into weld nuts), one row of coarse-thread screws (screwing into nylon blocks locked into the front fairing), and a single odd-ball shaped plastic fastener in the middle. The row of bolts holds the leading edge of the engine underpanel as well.
