I have the same problem with my 123. What threw me off was that it just started after I rebuilt my 301 and put it back in. I thought that if the shaft lived for so long being in the motor one way and now it's 180 off, maybe that's doing it. But, I can see the shaft wobbling quite a bit so I must have tweaked it a little during r and r of the motor or something. Bums me out but good to see you found yours though. And yeah, unfortunately you're going to have to split it. Not a bad job to do, looks intimidating but just a few steps and it's done. Leave the rear tires on, disconnect a couple brake linkages and trans to frame bolts and roll it right out. Obviously use jack stands for safety
