Curt & Johnny, I think the problem likely resides in the wiper "transmission", the part tucked under the gray center cover, which you can't access without fully disassembling the wiper mechanism. Lubricating the external stuff may help but will only do so much. I also had a slow monowiper when cold on my 300E, and swapped on my 300D monowiper instead, which works fine. (I put the later version "black" wiper on the 300D.)
Interestingly, the very late W124 monowipers (1994-95 model years) have a different transmission cover... it's a plastic cap that pops off so you can see, and lubricate, the internals. I got one of each (don't ask) of the two versions (Bosch and SWF) and the internals are TOTALLY different, but both were in dire need of lubrication. I'll be posting photos eventually. I wanted to install this type on my car but discovred - two days too late, d'oh - that you need the late windshield too, which has a groove for the new style weatherstripping. Alas, that will have to wait, for now. If anyone wants a 94/95 monowiper for W124, drop me a line... I have two I don't need! Here's a photo of the area that contains the 'transmission' internals: http://www.superturbos.com/misc/late_wiper1.jpg And no, that top cover doesn't just pop off! :) -Dave M. > ------------------------------ > Date: Tue, 28 Feb 2006 10:26:55 -0500 > From: John Berryman <[EMAIL PROTECTED]> > Subject: Re: [MBZ] 201 Wiper Sluggish > > > On Feb 28, 2006, at 9:48 AM, Curt Raymond wrote: > > > While we're talking wipers has anybody ever lubed a 201 wiper?
