OK...trying not to be long, but I think I've narrowed it down to the chain.
At my clubs event, I broke a rear drive shaft at the differential u-joint. Occured when starting from a stop in a twisted situation...front going up, rear doing down...wedged into the ditch. Twisted the ear right off and busted the tab on the diff yoke. Repaired with a spare ds and doner pinon yoke. After, had vibes that seemed less when in full-time 4-wheel.
Decided it was time for a build. Built and installed a Ford 8.8 rear axle with 4:56 gears and Ected limited slip/locker. Also built front axle with E-Locker with 4:56 gears. Also did Tom Woods SYE and rear CV driveshaft. After all the build, still have vibes.
To chase the vibes down, I removed rear drive shaft. With vehicle in 2wd in garage, can hear a "tick-tick-tick" that seems to be about the right timing for the t-case chain. With rear ds removed, vibes present on highway, worse upon decel, not so bad on accel, almost non-existent at "neutral" coast (not on, or off the gas).
Check rear output shaft...turns without any wobble (not bent)...good because it is a new shaft with the TW SYE kit.
Have had front DS rebuilt...rebuilt CV joint and U-joint, and balanced by a good driveshaft shop. Haven't checked front output shaft for wobble (yet).
Since hearing the "tick-tick-tick"...I'm thinking the chain got "stretched" when rear DS busted (all the torque transfered to front at the time of the break and taco'ed the chain).
I need to fix as it's my daily driver. Also...might not be related, but I've noticed that transfer case gets hot now...can't hold a hand on it after 10 miles of highway driving. Is this normal? Is heat related to chain?
I'm ready to buy new chain and do the install, but wondering if I'm on the right track. Anybody else ever experienced the same/similar issue? I love my 242 and don't want to go to 231...just want a highway-ready wheeler that can wheel the tough trails when required.
Thanks in advance for the help.
