In a fairly hefty “oops,” Jeep is recalling a few thousand 2020 Jeep Gladiators because the supplier forgot to put grease into the monoblock joint of the rear driveshaft.

Dealers finding ungreased joints will replace the driveshaft at no cost to customers; the recall is expected to begin in mid-October, and only affects certain Gladiators made from December 15, 2018 through June 25, 2019.  Not all Gladiators made within that date range are affected, but all must be checked.

The monoblock is a constant velocity (CV) joint in the center of the driveshaft; if it lacks grease, it may overheat and seize, fracturing the rear driveshaft. The part was supplied by Dana.

FCA US found the problem in June, with four driveshafts returned for warranty work; it appears that a production worker at Dana used a “grease bypass button” during assembly. Two more greaseless assemblies were found in the next two months. No crashes have resulted as a result of the problem, and only around 5% of the Gladiators in the population are likely to have the issue. The recall is #V95 or NHTSA #19V-636. The part number is 68330600AA / 68330598AA, and the part is found in the Rubicon, Overland, and Sport.

Update: Jalopnik reported that there is a stop-sale on Gladiators for this issue.
