The recommendation to change to manual lockout hubs seems odd; I guess it could help if this is for the 3" suspension lift and 1" BL where the rear of the transfer case is aligned lower than the front output creating problems with the front driveshaft u-joints. Unlocking the hubs would prevent the front driveshaft from spinning while cruising down the road.
Right, I got that but that's not addressing the root cause of the vibration. Having manual hubs would be great if you flat towed though.
I agree. I also donít want to spend the money on a manual hub swap.
My plan is to rebuild the front DS. Maybe even give Woods a ring and talk to them. If that doesnít fix the vibes Iíll go after the pinion angle. Iím not sure what Iíll do after that, but it may involve finding a way to tilt the drivetrain.
I read on another forum that the root cause was the transfer case shaft out of balance. The guy went through all options and then tore into tcase and found it to be the cause of the vibrations. IDK. I’m putting mine on a trailer, running beadlocks and may get a Currie D-60 setup someday. Tired of spending money on mine for awhile. Gonna wheel it till something breaks. Moab in late spring, Ouray in late summer. 67 GTO conv project starts in spring. Lol You guys figure it out, let us all know. Peace
