Helping my Buddy with a 69 4-speed Hemi RR track down a vibration issue. Noticed when under the car that the rear u-joint was loose (as in trunnion slid back and forth in the Dana 60 yoke. Caps were seated OK. Pulled the u-joint and it measured about 3.65 inches outside of cap to outside of cap which is a 1350 u-joint I believe. Next used calipers to measure the distance between the cap retainer tabs in the Dana yoke and came up with a dimension of 3.75 inches. So there was ten thousands to much width (seemed like more yanking the driveshaft side to side). I think officially a 1350 is supposed to measure 3.62" so could be as much as 13 thousands play. Nothing corresponds to that dimension of 3.75". After 3.62" 1350 the dimension jumps to over 4 inches - that may be a 1410 u-joint.
Anyone see anything like this before? It has a Spicer yoke I believe but I don't recall the number on it. At first I thought maybe it used 7290 inside clip caps but that doesn't make sense on a yoke with u-bolts. We're stumped.
