U-joint report

DETROIT POT STYLE UNIVERSAL JOINT REPAIR KIT PART NUMBERS
(Ball and Trunion U-joint)

I have been looking for these repair kits and have found out the following information. They are getting pretty hard to find. I live a stones throw from Pottstown, PA. In Pottstown there are two companies who make U-joints. Neapco is one company and Dana/Spicer is the other. I have been in contact with Neapco and was told that they do not manufacture them anymore and they have not for awhile. What is left is, what is out there, on the shelves, in the automotive parts stores, if they even have them. (Advanced Auto, Autozone, NAPA, Pep Boys....and all the rest.) If a store closes or gets tired of having these kits on the shelf they return them to the supplier for credit. Guess what Neapco does with them? They throw them in the trash. Hopefully not anymore. My contact in Neapco will be looking for the returns and selling them to me. So far I bought 2 kits numbered 7-4266 and 4 kits numbered 7-4268. I will explain the applications soon. I will try to contact someone in Dana and find out if they have any in stock. I do not know if anyone else is making these kits. I know that Andy Bernbaum lists the replacement boots for $22.50 and the repair kits for $75.00. I do not know where he gets his boots and kits or how many he has in stock. 

Here is a breakdown for the application of each repair kit. The application information was taken from Neapco Catalog No.UJ9900. 1999 Catalog. 

I CANNOT GUARANTEE THE ACCURACY OF THE CONTENTS IN THE CATALOG.

I hope that this information will be of some help in your search for these U-joint repair kits. To be sure what repair kit you need measure your U-joint body and compare that with the above specifications. The Neapco catalog only went back to 1957. What did the 1955 and 1956 Chrysler use. Does anyone know if they measure up to one of the above mentioned U-joints? If you know, please let me know so that I can update this report.

If you need a U-joint repair kit contact me to see if I have any. Availability right now is one repair kit 7-4266 and four repair kits 7-4268.
