Rear Leaf Spring Installation

Chevy Silverado 2500 Rear Leaf Spring
The rear suspension of the Chevy Silverado 2500 consists of leaf springs and shock absorbers. The leaf springs are held together using a series of mounts and shackles. To start off the springs get held to the rear axle through the use of giant u bolts. These U-bolts contain nuts on the bottom of them that must be torqued down to 118 ft-lbs. I always use some loctite on these nuts as if they come off your entire rear end will come loose. Besides the U-bolts the rear suspension has a series of mounts that connect the leaf springs themselves to the vehicles frame. The leaf spring mounting nut gets tightened down to 148 ft-lbs. The shackle nuts get tightened down to 70 ft-lbs and the hanger bolts tighten to 37 ft-lbs. The center spring holder pin can be torqued down to 30 ft-lbs. This ensures that the leaf springs all stay stacked together.
