Transmission & drivetrain Vehicle recall #98V180000 · 1998 · 3,062 vehicles

What's wrong: The transfer gearbox flange nuts were not properly installed, causing the nuts to loosen.

Why it matters: If the flange nuts loosen, the propeller shaft can separate, rendering the vehicle inopeative.

The fix: Dealers will inspect front and rear flange nuts and, if found loose, tighten to specified torque and secured staked at two places.
