General Procedure

NOTE: Install a new PTU any time the PTU has been submerged in water.

NOTE: PTU 's equipped with a drain plug are serviceable in the vehicle. They do not require PTU removal.

NOTE: Do not drain the PTU unless contamination is suspected. To drain the PTU fluid on PTU 's without a drain plug, remove the PTU from the vehicle. The fluid that is drained may appear black and have a pungent odor. Do not mistake this for contaminated fluid. REFER to Power Transfer Unit (PTU) .

NOTE: Fill level checks are done in-vehicle only. Let the vehicle sit 10 minutes after the road test before checking the fluid level.

With the vehicle in NEUTRAL, position it on a hoist. REFER to JACKING AND LIFTING for lifting points.
