What's wrong?
The rear lifting bracket on the 2024 Peterbilt 520 is a metal attachment point on the engine cylinder head. During service work, it gives a technician a secure place to connect lifting equipment when the engine has to be raised. The bracket depends on flanged studs to clamp it tightly to the cylinder head.
On these trucks, the studs used on the rear lifting bracket were the wrong length. The installed stud is 30 mm long, while the required stud is 25 mm long. The longer stud can bottom out in the threaded hole before it clamps the bracket with enough force. If the engine is lifted in that condition, the bracket can detach from the cylinder head and let the engine swing or fall.
There is no warning sign before failure. An owner is not expected to feel this during normal driving, because the defect appears when the engine is being lifted for service.

What's the safety risk?
A detached rear lifting bracket can let the engine fall or swing while it is being lifted, increasing injury risk for anyone near the work area. There is no warning sign before the bracket detaches, so tell the dealer about the recall before engine lift service or repair work. Repair is free at any franchised Peterbilt dealer.
