Carrying the legacy of its older brother, the Jeep Gladiator, the J10 J-Series pickup truck was offered in three trim packages: the Golden Eagle, 10-4, and Honcho. The Jeep Honcho became the most popular among the J10 model series line, which featured a Levi's Jeans interior and a roll bar. The Jeep J10 was powered by a 304-cubic inch V8 engine that could give out 210 horsepower. A lot of Jeep enthusiasts loved the J10 for its mean stance and all-around rugged functionality. Just like most vehicles, Jeep J10 owners should be aware of their vehicles common problems, and prepare themselves if they encounter these issues.
One of the most common problems with the Jeep J10 is its manual transmission. Offering a 3-speed auto and a 4-speed manual transmission, the J10's manual transmission often failed to engage when placed in the first gear. According to reports, the original production lubricant provided wasn't adequate enough to protect the transmission's first gear. Owners had a hard time shifting gears which lead to gear failure for some.
In 1982, Chrysler recalled more than 13,532 J10 Jeeps to fix the problem with the manual transmission. Owners were advised to bring their vehicles to the dealers, while dealers were instructed to replace the original production lubricant at no charge to the J10 owner.
The Jeep J10's fuel system also had several problems-specifically the 1981 year model. There were some Federal-Mogul aftermarket fuel pumps sold under the brand names of Parts Master, Parts Depot, TruFlow, NAPA, Carter, and AccuFlow which were either inadequately tested or improperly installed, causing the fuel pump to leak. The above-mentioned aftermarket fuel pumps were shipped between August 2006 and July 2007.
In 2007, more than 34,000 units were affected by Federal-Mogul's advisory. A notification campaign was launched by Federal-Mogul advising owners to contact their company for a fuel pump replacement-free of charge-to avoid creating a potential fire hazard due to the defective fuel pump.
Another common concern encountered by J10 owners was the faulty vehicle speed control. The cruise control module didn't respond accordingly, and was inconsistent at times. The faulty module needed to be replaced because the driver may lose control of the vehicle, leading to an accident.
In 1987, a total of 3,996 Jeep J10's were affected by the vehicle speed control problem. Owners were advised by Chrysler to bring their units to the dealer to have the module replaced.
