Recall 23V456 covers 1,865 2022-2023 Hino NE7A, NE7B, NJ7A, NJ7B, NV7A, and NV7B trucks for loose U-bolts. Dealer repair is free.
Hino is recalling 1,865 2022-2023 NE7A, NE7B, NJ7A, NJ7B, NV7A, and NV7B vehicles because the driver-side U-bolts that hold the front axle to the leaf spring assembly can loosen and detach. Loose U-bolts can reduce handling and control, which increases the risk of a crash; Hino dealers will complete the recall repair free of charge.

What's wrong?
The front suspension U-bolts on the 2022-2023 Hino NE7A, NE7B, NJ7A, NJ7B, NV7A, and NV7B hold the driver-side front axle tight against the leaf spring assembly. The leaf spring supports the truck's weight and helps keep the front axle in position as the suspension moves. These trucks use U-bolts for the 12,000 lbs front axle setup, with a spacer between the leaf spring and axle on the driver side.
On affected trucks, related parts were misaligned and the tightening torque applied to the U-bolts varied during assembly. That means the clamping force on the U-bolts can drop during operation. If the bolts loosen enough, they can detach, leaving the front axle no longer secured to the leaf spring assembly as designed.
There is no warning sign before failure. Do not rely on noise, ride feel, or a visible lean to tell you the U-bolts have started to loosen.

What's the safety risk?
Loose or detached front axle U-bolts can reduce vehicle handling and control, increasing the risk of a crash. Drive cautiously until the inspection is complete, and schedule the recall service soon because the front axle hardware affects how the truck responds. Repair is free at any franchised Hino dealer.

What happens at the repair
At the dealer, a Hino technician inspects and tightens the front axle U-bolts that secure the axle to the leaf spring assembly.
