1948 Windsor rear end U joint strap infor needed


Recommended Posts

I do not have the correct straps to hold the rear U joint on to my 1948 Chrysler Windsor rear differential (3.54-1 automatic tranny). As a result, the drive shaft slips out of alignment with the U joint and complete breakdown or permanent damage may occur. The only straps that I could find at a local parts store were for a '75 Chrysler and they are a poor fit.

Does anyone have or would take photos of the rear U joint assembly or possibly the page out of the shop manual that shows me the correct strap bolt assembly that I need?

I am not sure what other years this part fits. Knowing this would help broaden my search base past 1948 Windsors.

Better yet, does anyone have any spare straps for sale?

I have attached photos of the alignment problem that is causing the violent vibrations with the incorrect straps.

Thanks for your time.

Are you sure that you have the correct U-joint? it looks to wide. It should lay into the yoke. The yoke should have the side stops built into it.

It almost looks to be off center, too.

Jack, you may be correct. The u joint that I am using is a new one pressed into a 1975 Cordoba drive shaft. The when taking yoke measurements on the Windsor third member, the joint fit. That's not saying that I have the right style joint for the Windsor section.

Thanks for the input.

Those are the wrong U-joints! The caps that bolt to the yokes have wings with pre drilled holes drilled so the caps bolt directly to the trans/rear end yokes as the picture shows. C38 are smaller than the 8cyl C39 chryslers but look the same.

Find one with the right caps, that match the flange on the differential !!!!

Try NAPA; they furnished me with new U-joints for my '41 De Soto, replacing exactly the oddball "Mechanics" u-joint that has been obsolete for 40 years !

(Apparently my joints also fit certain Agricultural and contstruction equipment. )

Your Chrysler originally used Detroit Cross & Yoke joints, did not use separate straps, but had two bearing caps with mounting ears with bolt-holes through them.

Find the right joints !!!

Not worth having your car torn-up if that driveshaft gets loose!
