Keep roadwheel nuts tight.

Just because the roadwheel nuts on your M88A1 recovery vehicle are torqued tightly in place doesn't mean they'll stay there, mechanics.

In fact, with all the weight and pressure they're under, loose roadwheel nuts are almost inevitable. When one nut loosens, it increases the pressure on the others, setting off a chain reaction of loose nuts.

The roadwheel wobbles, snapping off the studs, and can cause a thrown track.

Look for shiny spots around the flat washer under the roadwheel nut. That's a sure sign of a loose nut.

Replace missing nuts with NSN 5310-01-064-3910 and flat washers with NSN 5310-00-809-9514. Retorque loose nuts to 320-350 lb-ft.
