working on my 1973 Travelall - long over due replacing u joints and center driveshaft bearing. Need some pointers. First - how do I remove this center bearing from the driveshaft? I don’t want to break or damage anything. Anyone know the correct Spicer or Timken bearing number to replace this? I don’t trust the online sources. The U-joints certainly look like a 1310 to me. O’reillys website is telling my that is not correct. I cleaned up an end cap and it has P591 on it. Pretty sure these things are original... So is 1310 the correct u joint??
