I just replaced my blades with the $8 walmart michelin blade. Did a quick test out on the driveway (raining today), and noise is gone! I didn't have any silicone spray, so it was a bit tough getting the new rubber to slide in. Other than that, very easy to do. Thanks, Paul!

nvm. i found the DTB for the noisy wipers on my computer if anyone needs it.

Please post

gaazmon

here you go guys. hope this isn't against web site policy.

Thank you. I still think the tension/angle contributes more to the chatter than the blades. I will ask the dealer to take a look at this next time.

Thanks for the info. I'll stop by wallyword to see if they have the Michelin's available.

As important as what has been discussed is the conditioning of the windshield. Some substances (a la Rain-X) used to coat the windshield will generate the noisy wiper blade action.

Like JoeVal implies, the reason blades chatter is: 1) blade condition 2) windshield condition. It can be the arm assembly pressure if it's become out of whack, but it's primarily the two things above.....

fwiw, I clay bar and wax my windshield. I know it sounds weird, but I learned it from a detailer.

Here's the trick: clay bar using Stoner's invisible glass as the lube. Then wax the glass. Also wipe the blades with vinegar and then with rubbing alcohol. Replace blades every year if you live in a bad weather place and/or park your car outside.

I clay bar twice during the winter here (we get rain during the winter) I have never had an issue with the blades chattering on any car I've owned after doing this. MB, Porsche, BMW, Volvo.

It's amazing the amount of sticky and tiny rough crud gets on the glass. Just like the paint (and why you claybar paint.)

Here' a claybar glass kit (but any clay will work, just use the Stoners for the lubrication): http://www.autogeek.net/griots-glass-cleaning-clay.html

And forget using Rain-X, imho. I found it can make chatter actually develop.

Just my 2 cents.

I've never had to treat/clean the windshields on any of my other cars, nor have I had to change the blades so often. Getting back to the michelins...it rained today. It chattered slightly on the first few passes, then got quiet. I'll keep an eye on it

Vik888

Yeah, Rain-X actually caused my blades to chatter .. this is on an 08 E550.

Guys I just changed mine for $7. go to advance auto parts and they have wiper blade refil which is just the rubber part, get size 26". get that for only $7, I think it says on it 26-28" so you can cut it for the existing length. now remove your old wiper. now you will need a plyer to remove the old rubber wiper from the assembly. once you remove the old one lay it side by side to the new one and cut the new one for this size. once cut you can insert the rubber refil to your existing assembly.
I just did mine and it works like perfect.

tbone

That's what I did with my $8 walmart michelin blade. Mine is still quiet

just got the bosch aerotwin 3397118948 from amazon.com

so far so good since monday. half the price of the dealer.

I picked up ANCO countour replacement blades at Autozone over the weekend. There was a manager's special for buy-one-get-one-free; two wiper blades for about $20. Installed in less than a minute and they've been working great all this week through the crazy CA rainstorms. No squeaking at all.

Does this fit the arm as the OEM or did you have to modify it?

gaazmon

it fit the arm perfectly for me. just raised the old ones, pulled them out of the hole, put the new ones through the hole and that was it. I believe this bosch part is the factory part, since the one i had from the dealer said made in belgium on the center and had the bosch trademark symbol vs these say bosch instead, but i believe they are the same.

i think it was $33 and qualified for free super saver shipping. i ordered it thursday. it shipped out friday. i got it monday. the same part was $60 at the dealer for the set and $120 for the set for my CL500 even though it's the same length wiper blade.

the amazon web site even has a fit guide for which part number fits which cars. i found this one since it stated it would fit for e, sl, cls, etc. i also found another one for s, cl, and maybachs.

vettdvr

You are correct. I check AZ and found them ordered as you did the 3397118948. I confirmed the part number from the Bosch site as OEM parts.

The actual OEM part # is A 211 820 14 45

Thanks for the info. rainy season is comming and based on the stock market I better buy them now while I still can.

Barry45RPM

Any Idea why the dealer's parts dept always asks for my VIN when I get wiper blades in addition to year and model? That would make it seem that depending on production date there are different wiper blades for the W211, as opposed to the one part number on the Bosch website and at Amazon?

gaazmon

ya, the rain has been really coming down here in CA and it's heading east.

jeez, don't even get me started on the stock market

Day 5 of the rains, and wipers are still good.

Does anyone know if there is a way an indy shop, vs a dealer, can adjust the wiper arm angle? Can they have access to the data? The wipers are perfect right now, but i'm just worried if the angle problem kicks in again. I don't want it messing up my new set of wipers.

Rain try surviving Katrina and I'll show you some rain. But I totally understand folks flooding in Arizona, we have family there.

Stock market,, what stock market?

Back on topic.

I found on AZ free shipping 5 - 9 days. So I selected the free shipping. Best price I found local on wiper blades was $50 for direct fit w adaptor.

I really don't like adapting something to fit unless it is duct tape on my sons 72 Chevy with a leak in the top rad. hose I told him to change. But that was 20 yrs ago.

gaazmon

well it's funny since the CL/S use the same length blade as the E/SL/CLS, but the latter costs $60 at my dealer vs the former costing $120 . guess what... on amazon, the price difference between the 2 is like $3

Guess they just want someone to support their economy during the current depression. ooops recession.

Followed your advice, however the rubber blade was too wide and wouldn't fit the oem arm.
Anco Advance blade was 8mm vs 4 mm for the oem.

@Clinton, apparently the Anco Profile has almost doubled in price since your post.

starbrite

Walmarts, in my area, carry the Anco 31-26 @ $5.97 ea and the rubber insert removes easily and fit the oem blade perfectly. So far it is very quite-no more chattering.

Took 5 min to remove and install. As paulv stated in a previous post, silicone spray makes the job uber easy.

Edit : btw, I believe the Anco "Profile" blades have been renamed "Contour".
