What's wrong

PACCAR Incorporated (PACCAR) is recalling certain 2015-2023 Peterbilt 320 and 520 refuse trucks equipped with Haulmaax/EX suspensions. The suspension tracking rod brackets may fail and detach from the forward drive axle, causing the axle to become unstable.

Consequence

An unstable axle can decrease vehicle stability and control, increasing the risk of a crash.

Remedy

Dealers will inspect the welds and add an additional bracket between the tracking rod bracket and axle housing, as necessary, free of charge. Owner notification letters are expected to be mailed February 14, 2023. Owners may contact Peterbilt's customer service at 1-940-591-4220. PACCAR's number for this recall is 22PBL.
