Wiper arm and blade upgrade for CJ

Hey all, I am in the never ending process of upgrading my 83 CJ7. I would like to replace my stock wiper arms and wipers with something more stout. No interested in the wiper boy modification at this point, was just wondering if anyone has removed the old wiper arms and replaced them with a sturdier wiper arm from another vehicle. My stock wiper arms are so cheezy. Would Yj arms possibly fit? Was thinking of taking an arm to the auto parts store to see if they could match it up with something else.

There was a thread here a few years back about modifying the rear glass wiper arm from a Ford Escape. I remember that because we have an Escape that I've never used the rear wiper so I'll only have to hunt one. Google is your friend.

Then I rediscovered Rainex!

Here was my solution to using newer aftermarket arms and blades. https://www.jeepforum.com/forum/f8/3...0/index54.html See post #804

CJ and YJ wiper arms don't interchange. The drive head of the YJ is larger. YJ on the left, CJ on the right. The windshield frame in this picture is a YJ. I run a YJ tub, with YJ w/s frame, so YJ wipers.

In the past I have walked through Auto salvage yards and snatched various arms off of various vehicles----old and newer.

I found the CJ arms to work fine------if you replace the spring with one a little shorter, even bend a new hook on one that will fit in the arms width (springs come in different widths)

schardein's pic above will show what I'm saying.

Recently I bought some black arms from Kaiser Willys for my '77 CJ-5---I like them!----I will be getting springs to make them hold down a little tighter too!

One of my wiper arms over rotated and got hung up, bent and cracked the windshield frame. I converted to YJ wiper arms/blades. You have to enlarge the wiper arm post holes and use YJ wiper arm/blades and the YJ wiper arm linkage. The CJ motor is still used. The YJ arms and linkage are larger and should hold up better.

See if this helps...


I did this mod and really like the wipers now. The only thing I changed is that I did not use pop rivets. I used a blind fastener I found at Home Depot.

No need for such a big hack. The anco arms are much stouter and you can even fit the upper part of stock arms in there

Thanks for all the great options to upgrade my wipers. I will start with the trico 37-111's first and go from there.

I bought arms and blades for the rear of a 2006 ford escape. I saw a thread somewhere on this, and it worked out really well. You just replace the ford splined socket with the one for the jeep.
I made the right thickness washers to center the arm on the socket. (you could just stack a couple of washers on each side) works Perfect! and I can get replacement blades just about anywhere.
