Wiper Slap (Insight Needed)

[NHouston]

Wiper on driver side has developed a slight slap to my pillar when only on high setting. Anyone experienced this on your 200?

I know I can remove the cover on wiper arm to get to the wiper arm nut. However what is trick to adjustment? Do I just loosen the nut, push arm down a couple mm, and then tighten up nut again?

I posted the fix somewhere, but even I couldn’t find it in the search. It’s not an issue with the splines on the wiper motor assembly.

Your wiper arm itself is slightly bent. The area in the arm that transitions to the j-hook, bend that area just a little to return the angle back to factory.

If the arms get bent, it changes the pitch of the wiper blade, which can give enough angle to hit the molding.

When I bought mine used, it did the same thing. I took everything apart, inspected everything, and I finally found that was the cuplit.

No worries, it’s not broken, unbolting anything won’t fix it, just play with bending the arm a bit, and it will be right back to how it started off. It usually happens when glass replacement workers treat your truck like anything else that isn't theirs... like crap.

I think I am running standard wiper fluid.

I recently switched from the Toyota Sight Line wipers to the Toyota OEM Factory Wipers. That is when I noticed the slap. It does it slightly on when my wipers are on high settting.

Ragingmatt-where you able to bend or adjust your wiper arm to fix slap? Or just living with it?

I just pulled the wiper bolt and shifted them on the mount. Mine, on a 2016 LC, slapped pretty much from new, even through a wiper change. I assumed they were installed late on a Friday. I complained to the dealer once when in on an oil change and they "couldn't fix it" for some lame reason. Last winter was the first time we had enough rain in N. Cal that I was annoyed enough to seriously deal with the issue. I had checked out a new LC on the dealers lot and found that the arms on it rested lower on the windshield than mine. The angle change along with a change in blades also fixed an irritating streaking problem.

After reading this thread I will try to remember to take a look for bent arms.

Just to elaborate the comment I made about a bent arm.

When I say to bend the arm (the area on the arm where is transitions from a c-channel shape to the j-joke) back to factory angle...

I am talking about a bend of a couple degrees. Like, on mine, I was hitting the pillar enough to make an annoying sound.

Adjusting the splines proved that I was on the right spine. One spline either way was either off the windshield completely, or about 6” from vertical at full wipe.

So bending the arm, again, just a tiny amount, for my 3°, got the wiper blade to sit perfectly vertical at full wipe and with the exact same space from the wiper blade to the pillar on both sides of the wiper.

So please don’t think I’m saying to bend the heck out of your arms. It’s a tiny amount, which is why it doesn’t take much to get a wiper blade/pillar impact.

You’ll never be able to see it just looking at the arm. It’s just something you need to swipe, bend, test. Over and over till you get it right.
