My 4 wheel drive is currently inoperable due to the A.D.D. (Automatic disconnect) not operating.
I had issues previously and had the unit removed and cleaned/soldered while working at 4WP. All was good until a few weeks ago.
Unit is not functioning at all and currently only have a 2WD vehicle.
There are a few ways to remedy:
R&R the A.D.D. with a Toyota replacement unit.
Slide the locking collar and be full time 4WD.
Replace the A.D.D. with the axle tube from a manual truck.
Anyone have experience?
