Field notes

Lug nuts, suspension U-bolts, and hanger/shackle bolts — the fasteners most responsible for a wheel or axle failure on the road. Covers travel trailers and fifth wheels through Class A motorhomes. The wheel/axle manufacturer’s spec always governs. Torque values below vary by wheel maker (Lionshead, Dexter, Lippert, and others) and stud size — use these as a sanity-check range, not a final answer. Always check the spec plate or the manufacturer’s current manual before torquing.

Lug Nut Torque (Conical Seat)

Re-torque rule: re-check lug torque after the first 10–25 miles on any newly mounted wheel, then again at 50–100 miles — fasteners seat and settle under initial load. Torque in a star/cross pattern, never sequentially...

Suspension U-Bolt Torque

Check U-bolt torque with the coach’s weight on the tires (not jacked up), every 6 months or 6,000 miles — whichever comes first.

Hanger & Shackle Bolts

Equalizer hanger and shackle bolts on leaf-spring trailer suspensions typically torque to ~35 ft-lb. These should move freely (they’re a pivot point, not a rigid joint) — over-torquing can bind the equalizer and cause...
