Ok I am guilty of this also, after reading many of the posts here I have seen that many of use W126 owners don't have the right wiper cages on their cars.
These are them, from Fastlane:
P7032-19643 Wiper Blade Set Bosch IN STOCK $74.96 $57.69

The ones you get from Autozone are not the right ones, I just went through this I didn't want to spend the money. But the cheap ones do not work right and will cause problems. This is just part of owning a W126 you need to buy the right wipers.

Just for the new guys most W126 owners seem to have the same problems.

Maybe that's the case for the SDL, but the SD is just fine on some ANCO wiper refills I bought for $5. I usually get original equiptment quality parts for my car but $60 for a wiper?? Bosch, get real. Don't tell me a pair of wiper blades is worth a new set of glow plugs, new primer pump and a handful of filters! There are a few things out there which I simply cannot accept the pricing on, and those are one of them. Why so much?

I agree Pete. I bought the Anco blades 3 months ago and they work fine. Now I can buy $7 refills. Works for me.

Based on the recommendations of someone here on the forum, I took the plunge and ordered "silblade" (www.silblade.com) wipers for all 3 of my MB's. They are reportedly better than the OEM's. I have had mine on the 123 for about 2 weeks, my 126 for 1 week and my 107 for 2 days (no rain yet).

So far, they are fantastic. No chatter or missing at high speed and clearly a high quality silicone blade. They really appear to be top quality.

You won't save any money as they are about $25 per blade. But if they are better than OEM Bosch blades, then they are a better value.

Hattie, lets start a new thread............how many months till our blades start crapping out. Sounds like we are getting a pretty even start on this one.

No these are not the blades, these are the cages that hold the blades. The proper cages have tabs that grab the arms and do not cause them to "chatter" when going across the windsheild. There also is a right and left. These cages are W126 MB specific cages. The refills are a few bucks.


I spent about $12 each for the wrong cages and used little screws going through the hole in the arms to stop some of the chattering.

Sure Alan but my regualar blades seem to last almost a year. Can you just get the silicone refils?

Done with the "parts store" blades. The Fastlane Bosch are great for me. Just got a new set in last week - "just in time for the rain"

OK, I see the blades are about $30 for my car, and a pair of refills $21. I still think that's pretty expensive. What is it that makes them so much? I can understandthe arms a little bit, but the refills? Also, what's different right and left? I never noticed

I bought a Bosch refill as a spare, single blade, for my panaramic wiper, it was $19 and when the time came to replace the blade I discovered someone had switched my Bosch blade cage to a cheapie!

Must have been done in a parking lot somewhere!

I have wanted to replace the cage, or wiper, as the catalog describes it but oddly there are two different wipers for the Bosch panaramic!

One is Bosch #3.397.002.930 :612mm

The other is Bosch #3.397.012.091 :612mm

Price difference is about $3 between the two! Does anyone know what the difference is? Lenghth, width, fit, what????? BB

I've never been successful using the aftermarket refills in the M/B arms. The chatter would begin within a very short period of time. I recently replaced both the arms on the SDL with the OE replacements (available from PP). I'm not sure if Fastlane supplies the OE arms or the Worldpac equivalents.

I figure that the replacement arms will last another 18 years or so. Works out to about $3.00 per year for wiper arms. And, then you can use the proper inserts for them.

BTW, I had purchased the wiper arms for $20.00 each less than four months ago.

I don't understand what you all are referring to when you say "chatter." I replaced my wipers with the most expensive bosch units they sell at autozone, but sometimes when the wipers are on their highest speed they sound like they are traveling too far and make this annoying noise. Is this the chattering you all are referring to, or do I just need to have them adjusted??

Refer to thread:
wont start for anything! 1985 300SD

Post #109 for a better understanding of why the parts-R-us wiper arms will not fit.

Just finished my hour and a half commute this AM - rained the whole way. Cheapo Ancos worked great. Maybe I just got lucky, but I've had them for three months and no problems.

I still don't understand what the fuss is about.

Different people appear to be using different terms for the same parts, so I can't tell if we're talking about arms (that connect to the wiper motor, who ever replaces these?) or the blades (that hold the rubber strip that touches the glass, sold on its own as a refill).

I have non original blades on my car and they handle the Seattle area rain cleanly and silently. Any sweeping statement that proposes absolutely that non original blades will not fit or will not work is, with respect, wrong.

Basically, aftermarket products don't always agree with MB's. The aftermarket cages, which hold the blades don't always work as good. They may work for awhile but they begin to squeal and clatter across the windshield. Aftermarkets usually end up costing you more in the long run. Just like Brake Pads. Not all Brake Pads work well on MB's. They work awhile then they squeal. So it sometimes pays to pay a little more and get it right.

So it makes sense to fit the original wiper if you encounter problems, but if you don't - why bother?
