Howdy, I just picked up a set of front and back Weathertech mud flaps for my 2019 Forester. I ran into an issue with the rear mud flaps and I'd appreciate any advice you can give me.
There are three mounting mounts used, one on the underside of the fender, one on the top outer edge, and one tucked back in the wheel well. The mount point tucked back in the wheel well uses a longer clip than the other two. When I tried to install them, the issue I ran into was that the picture the instructions show for where the clip should install (and the orientation of the fender liner) don't match up with what my car has. The fender liner wraps the inside of the fender and drops down over a hard plastic piece behind it. From what I can tell in the instructions, the clip should latch onto the hard plastic piece behind the fender liner, but the space is so small that I wasn't able to get it clipped in (plus, there's no space between the plastic piece and the metal frame). The clip is too short to clip directly onto the fender liner.
Did you run into a similar issue? If so, what did you do to get it installed?
On a third look at it.... I realize now that the picture is showing the fender liner being bent up 180 degrees right where the mount point is. The fender liner seemed pretty rigid.... is that safe to do without breaking/tearing it?
I recall that one of the clips was a little close on the alignment, but it all went together with no fuss.
I had to temporarily move the fender liner a bit to install a clip, but nothing major and definitely did not fold it back 180 degrees.
I took a look at my mudflaps. Below I am referring to the left rear mudflap.
Just to the right of the hole giving you trouble is another plastic fastener. Removing that fastener makes it easier to bend back the liner to make room for the clip installation. It makes the bends less extreme as well. I do not recall needing to bend the liner as much as in the photo, and at no time was I concerned about damaging the liner. I tried to apply common sense and keep bends gradual.
Behind the liner is the harder plastic which the clip slides over to align with the existing hole. This is where I recall things were a little tight and thinking, unlike the other holes, there is zero slop in the alignment. I slid the clip over the plastic piece, maybe using a screwdriver on edge to push it fully on. I don't recall any issue with underlying metal.
In your case, it sounds like the hole is a tad farther from the edge than the clip can handle. If that's the case, could you file away some of the plastic to allow the clip to slide closer to the hole? It's covered by the liner, so you don't need to be neat about it. A rotary file (Lowes or Home Depot) in your drill, or a dremel tool would also work.
If none of that appeals to you, I'd call weathertech. They likely can send you an even longer clip.
