How can I test for correct operation (in a controlled environment - like in the driveway)? I have CDL, so can disable ETC for the 'test' if necessary. Any ideas?

Then you hit the gas. The TT should send power to the side that is on the road. With mine, I took off the rear driveshaft and engaged the CDL and did the same. You can definitely tell the difference.   Nadim Samara (Discodino) Member Username: Discodino Post Number: 67 Registered: 02-2003 Posted on Tuesday, June 10, 2003 - 04:08 am:    no "psst, psst" sound, no work   Bruce Potier (Brucep) New Member Username: Brucep Post Number: 3 Registered: 06-2003 Posted on Tuesday, June 10, 2003 - 05:40 pm:    John, you know it's working by the way the steering feels, rather heavy or 'thick'. Also, when you are coming out of a corner, it will want to straighten the line very fast. Off-road, just ask someone to watch. Then if you hear the "psst" "psst" sound, you have other problems.   Milan (Milan) Member Username: Milan Post Number: 219 Registered: 10-2002 Posted on Tuesday, June 10, 2003 - 06:25 pm:    Do the gravel/dirt/pavement thing. The wheel in the dirt should spin momentarily and then slow down to the speed of the wheel with traction. To check if everything was installed OK, jackup one side of the axle, leaving the other wheel on the ground. Transfer case locked and transmission in gear (manual) or park (auto), rotate the lifted wheel. It should rotate freely in either direction.
