The Race to Moab - 2011
Decided to start tearing down the 4Runner to get it ready for Moab in 3 weeks. I noticed some drivetrain vibs while snowbashing with DIRTCO in Breck earier this year. Same with snowbashing with my buddy Brandon last weekend. So I pulled the cases to check them out along with install my new twin stick.

Trying not to make a mess but anytime I'm working with gear oil, it's bound to happen

Have to remove the reduction box from the rear case to install the twin stick

Not good. Found a loose ball bearing from the bearing around the coupler

That's probably my driveline vibration.
So, I called my buddy Joe and he's got the same dual case adapter (10 degree rotated version though) and I was going to take the bearing from his adapter. My adapter must be old because it looks nothing like his adapter. I'm hoping the bearings are the same. I'll be calling Marlin in the morning to see if I can swap the bearings without issues and to order a new bearing. Not really what I was hoping to see 3 weeks before Moab.
