VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1912-1928 1928 drive shaft U joint

Does anyone know where to find a u joint for a 28? If not can they be rebuilt?

. The Trunnions are supposed to wear out first but usually the Yokes also wear. The part number for 1926 - 39 three speed trunnions is #351888. Part #352813 fits 1928 - 31 four speed U-joints. The picture below is a 27 4-speed.
It has square drive in and 10 spline out. .

I have a couple ujoints but not sure what they are for. I can send pics of what I have tomorrow either email or text. I believe I have one like Lou's picture and some with 10 spline on both ends but have to check to make sure. Let me know, greg

. The U- joint for a 1926 - 29 passenger (K, V, AA, AB, & AC) 3-speed is part number #343881. The U-joint for 1926 - 31 Utility truck (X, LM, LO, LP, LQ, LR, LS, & LT) (NOT 1926 R nor 1931 M) 4-SPEED is part number #365026. These all have 7/8" square drive out of the transmission. There is another popular make of vehicle in the 1920s that has 13/16" square drive. Measure before you buy! .

I checked the joints I have and only one is 7/8" square drive with speedo gear and 10 spline to the drive shaft. The part number on the longer (driveshaft yoke) is 357493 no number on the shorter trans end yoke. Overall length is approximately 5-3/4"

. Part number #357493 Group 5.555, is the rear yoke for a 1930 - 33 three speed passenger and half ton except for 1933 "Standard" (AKA: Bastard). This is possibly because the Bastards used a riveted U-joint not sold separately. .

Wow! You guys are all over this. I do not know what I have yet, I am planning on pulling the drive train in the next couple of weeks. Once it is separated, I will take some pics and post them. I believe mine is in good shape, however there is a knock in the tranny area. This only occurs in first gear, and will fade in and out at higher rpms. I am thinking 1st gear bushing or the u joint. leaning more towards bushing, since there was the tell tale shiny brassy flakes in the trans fluid when I changed it.

Thank you gentlemen for the information, I will post pictures when apart.
