Terex Corp. is recalling 209 front-discharge concrete mixer trucks because the u-bolt attaching the front axle to the leaf spring might fracture, which could lead to separation of the front axle from the vehicle, the National Highway Traffic Safety Administration reported.

The recall affects 2013 model-year Terex Advance FD3000, FD4000, FD4000B, FD5000GL, FD6000B, 4 Axle Glider, 5 Axle Glider, 6 Axle Glider, and 7 Axle Glider front-discharge concrete trucks. They were all manufactured October 2012 through October 2013.

Terex dealers will remove the u-bolts and attach the front axle to the leaf springs using plates and studs. There will be no charge for this service.

Truck owners can reach Terex at 1-605-882-4000.
