Wheel Lugs

[slmartin464]

This is my third 5th wheel trailer. On my first two never had to tighten lugs after they seated. This rig never seats, any suggestions?

Hi,! Do you have aluminum wheels? My experience has been that they are real "bears", to keep tight!Forest river, for one ,has had a recall on some of their alloy wheels/lug nuts, for just this reason. Barring that, wire brush the inside of the mounting flange on the wheel, and the hub, get 'em REAL clean, torque to specs, and keep it up ! CROW

Mine stay fairly tight. I torque them before we depart on a trip and then every three days or so when traveling. I seldom get more than one flat of movement on one lug of six per wheel.

I've got steel wheels on mine, and the lug nuts have never loosened at all in 4-1/2 years.

Ken, you have the answer in steel. Aluminum does not have the compression strength, nor the "memory" of steel. That is the exact reason aluminum wiring was banned in mobile homes, it would flatten when the screws were tightened, then become loose from normal vibrations. A fire from the heat of electrical resistance, was the usual outcome, the lesser result was higher electric bills.

Thanks for the reply. I found out the steel wheels had 9/16 inch holes not allowing the 1/2 inch cone nut to seat properly. I drilled out the holes to 21/32 and put a 60 degree taper to match the cone nut and problem solved.
