The wipers on my 1995 LX are getting "draggy" and it seems like there is a lot of slop in the linkage, so it's time for a rebuild.
I can find the motor, but the Arm and Pivot Assembly is a problem.
The OEM part # is F6SZ17566BA.
Tasca has LC4Z17566A in stock.
Dorman lists their 602 304 as a replacement for 4F1Z17566BA.
Does anyone know if either of these parts is a bolt on replacement for the OEM F6SZ17566BA?
Thanks!

I would replace the blades first. "draggy" sounds like it would be caused by blades. It is hard to find a good blade these days that doesn't make some kind of noise. Most of them seem to need "seasoned", or go thru a few rainstorms before they stop making noise, at least on these cars.

Don't underestimate the importance of good blades. My Dad's wipers stopped working in a heavy rain storm on a long trip. He assumed it was the motor, but replaced the blades just to try. Fixed him right up!

I had 220k miles on my old T-Bird, they worked perfect. They always have a little "slop" in the linkage, meaning you can move them back and forth a little.

The blades are brand new Motorcraft.
I'm talking draggy as in moving very slow, like the motor is struggling to move them. Not making noise, and moving slowly, even after I spray windshield wash to lubricate the blades.
I haven't opened it up yet, but I think that the wipers don't get used much and the linkage is seizing up..

Try disconnecting the linkage from the motor, and see if the motor is seizing up.

It may be, due to lack of usage.

My Cougar has a similar issue. The wipers have a bit of play in them, you can move them by about a 1/2". They feel much less solid mounted then they should be. My assumption is that a worn out linkage bushing is causing this. I have looked around here and haven't found much for replacement bushing part numbers or anything. I have yet to pull them out and see what the issue is. One of the many little things on the list of "get to it someday"....

My linkage has plenty of slop in it too.
I'm pretty sure that the linkage has seized up from lack of usage.
I plan to do a complete rebuild when I get in to it, so I want to have the parts on hand before I take the system apart.
I've spent a few hours doing parts number research and find that excepting the first four letters/digit prefix that the part part number for the 2004 Sable has the same part number for the linkage, so I'm going to take a chance. The Dorman replacement arrives Tuesday.
That trick worked when I couldn't find a clockspring. There is a lot of commonality in parts between the Thunderbird and the Taurus/Sable line.

When I rebushed Ruby Jean's wiper transmission, I had to take some Dorman closed cap bushings and drill a pilot hole in them.

The idea of crossing the parts numbers to one of the Sable/Tarus numbers didn't work. I matched everything but the four digit prefix on the origional part number, then tried the Dorman equivalent. Not even close, and two inches narrower.
I'm now waiting on a used unit from TBSC.
