Kraton Rear differential out drives with filler ?

[hungrybird]

Saw this today when checking some bearings . No left to right moving , tight . No issues . Just thought I’d share . Every other dog one has some play except the rears . There’s a good 1/4” of rubber material in there and seems to work good as I have no issues

thats to keep your shafts from over extending if you want to "upgrade them" or replace them this is what i run

As @HoppyHop84 suggested or AR311028 (*for EXB outdrives).
