Known issues on the 1986 4000. Three recalls are on federal record for this model year. The first covers the axle assembly: differential oil is lost over time to evaporation, and the resulting low oil level causes premature bearing and gear wear that can lead to differential failure, a loss of drive power, or in extreme cases the front wheels locking and rapid deceleration. The second covers the vehicle speed control system, where excessive wear of the idle stabilizer can cause idle fluctuations and unsatisfactory driveability. The third covers the front seat belt buckle assembly, where the rear or front right seat belt locks may not properly engage, risking separation under heavy braking or impact. Owners have filed 4 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From a differential oil check to a seat belt buckle inspection, it keeps you on the OEM procedure and the correct specification for your specific 1986 4000.
