Elevated severity
This campaign addresses a defect NHTSA classifies as carrying elevated crash or injury risk.
What the defect is
Chrysler (FCA US LLC) is recalling certain 2018-2019 RAM 1500 trucks. The rear differential may have been insufficiently filled, possibly resulting in its failure.
Why it matters
If the rear axle assembly fails, it can cause a loss of drive or the rear wheels may lock up. Either scenario increases the risk of a crash.
The remedy
Chrysler will notify owners, and dealers will inspect the rear axle oil level. Rear axles with an insufficient amount of oil will be replaced, free of charge. The recall began September 26, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U88.
What this page does not include
NHTSA's public recall feed does not supply an affected-population count, the manufacturer's own campaign number, owner-notification dates or a defect chronology for this campaign. Rather than estimate them, we omit them. Confirm whether a specific vehicle is affected — and whether the repair has already been done — using its VIN.
