Drivetrain binding in tight turns

Post by Dungeness »

Had a problem with the drive train on my 2000 Safari binding in tight turns. Went on-line and most common diagnosis was break-down of transfer case fluid which was causing drag within transfer case. Replaced with Trac 2 fluid and it improved but only for awhile. Wasn't until winter when the AWD light came on that I discovered the problem was actually the transfer case emulator failing in a partly engaged position creating drag between front and rear axles. Replaced emulator and all is well!

Glad you got it fixed. The encoder motor is the most common failure of the NV136 transfer case. Makes most of wonder why they went away from the BW4472 which very rarely failed!

Here, here!! Why would you move away from such a reliable mechanical (guess I can call the viscous clutch that) system to something with electronics controlling it. Makes NO sense to me!
