I’ve been hearing a sound from the rear end of my 60 for the past few weeks, so I dropped the driveshaft today. Between the rear pinion flange and the transfer case output flange, it’s exactly what I’m hearing. The sound is mostly going into first gear and on slow speed turns. It sounds crunchy. Wondering if it’s time for a new rear diff, a transfer case (and transmission while I’m at it) rebuild, or if I should just run it.
-Rear pinion has rotational play, but not lateral play. Pinion nut was found loose last summer. Took it to Western Driveline in Aurora and they said diff looked great. They set preload, tightened the pinion nut back up, and sent me on my way. It’s still tight and staked.
-Transfer case flange has rotational play and a slight amount of lateral play. Nut is tight, but it looks like it’s moved because the staking appears to have shredded itself.
-I know the seal in the split case leaks because t-case fluid migrates to the transmission. It’s a small amount, and the t-case is pretty close to full (3/8” below fill hole).
-Rear diff fluid is full. Both rear diff and t-case fluid were changed in March.
