Gen-one windshield wiper guru needed.
Ok I have a dumb question,
Without pulling them out to check are the left and the right side windshield wiper pivots symmetrical and interchangeable?
Are the lengths of the bellcranks (pivot to stud) the same on both sides?
Reason I am asking the other day it started raining so I turned on my wipers and I heard a slapping sound as the drivers side wiper end was extending about 6 inches past my windshield but I do not remember it doing this before, I had it all apart when I replaced all of the bushings abour 6 monthe ago but I marked the sides using a sharpie as I took them off.
Do not see any other way to change the geometry and synchronization of the blades.
Got to be something dumb.
Thanks in advance.

Aaiii aahhh....... You are the Gen 1 guru.
Wiper pivots are the same (according to the parts book). Connected by tie rod. Maybe you have a long blade on the driver's side.

Could the wiper arm have slipped on the pivot drum?
and I do think the push pull rods are different lengths. My dad should know but he is at the coffee shop right now. I will ask him when he comes home.

Once I had the little clips that hold the rubber part of the wiper to the metal wiper frame come loose and the rubber slid out about 6". The arm and attachment point were fine.

Ok,
Here is what I am talking about, it is not the blade that slipped but the blade takes too wide of an arc across the windshield, the arm is tight on the spline and the blade sets level with the window rubber.
I just replaced the blades last week with identical blades that I took off that were both the same size, got the Michelin ones, you can see the marks on the windshield where they used to ride, I am pretty sure they did not slap the side glass before.
I would think the tie rod would connect farther from the pivot point on the drivers side to give it a shorter arc.
I have already tried swapping both arms, flip blades 180*, readjust blades,
while watching both blades operate, it seems like the drivers side blade travels faster.
The last time I had to replace the bushings, it stopped with a hard clunk, thinking I might have bent something.
Is there a way to connect the linkage wrong?
Your thoughts?

According to the parts diagram, the pivots are the same, the wiper arms are the same, the pivots are tied together with a link, making a parallelogram, so the sweep angles should be identical.
The Driver's side pivot lever must be bent, effectively shortening it.
I've noticed on mine that the driver's side wiper travels a bit closer to the edge of the windshield when it's going fast, well lubes with a downpour. I'm thinking if it's getting "thrown" that far, the lever on the pivot might be loose.
Looks like yer going to have to get into the cowl.

I once had a weld on the shaft that goes through the cowl break It did something very similar to what yours did.

^^^^ Two votes.
You should be able to grab the wiper arm and feel said play. Use the passenger side wiper for comparison.
Shouldn't be a big deal to pull the pivot and spot weld the offending joint. You'll have to pull the cowl plenum cover to get to it.

To the best of my recollection they are different. I found this out the hard way. I believe they have an L & R stamped on them. I haven't had mine out for a while. Mike

Actually, looking more closely at the page from the Parts Manual shown above; on one side the pivot part number is 4114 240 and on the other side it is part number 4114 241.

There is only one part number 4114 240-1 that is both parts. the dash 1 is probably a revision.

I just spoke to my local Mopar parts desk:
4114 240 is the passenger side and list price is $55.00.
4114 241 is the driver side and list price is $66.30.
Both parts have now been discontinued and no dealer in the US is shown to have either part still on the shelf.

Back to Jim's original question. If things are reasonably tight, he probably swapped them.

I agree, but it seems to be the way the nomenclature in the Parts Manual is always presented. The only reason I know this is that late last week I ordered a new OEM motor for my electric window regulator and was thoroughly befuddled by this left-side, right-side issue.
