Wheel Lug Torque Specs

[Huntsvillian]

Just wondered where everyone torques there lug nuts too. The OM says an acceptable range is 95-120 lb/ft. I tightened mine to 115.

That is what is in my spec book, but it says to do it in 3 stages.

I did not know what they were already at, so I adjusted the wrench until it clicked, most were set at 90, so I then set it to 115. Think it would be better to loosen then do them from scratch?

I am guessing the purpose of stages it to allow for even tightening.

Due to my being over safe (some would call it bordering on paranoia! - I double check everything!) I went out and backed off all the lug nuts on each wheel then torqued them to 90, then to 115............It appears the dealer only tightened them with the impact gun and then by hand or to only 90.

Better safe than sorry.

My rig has the Dexter TORQ-N-GO wheel nuts. I had never seen them before and I am very satisified with their claims to provide 200% more clamping load than regular lug nuts.

I don't think they came on later models, not sure.

The torque is the same.

For 8 lug nuts, 16"rim, steel/aluminum or chrome.
Stage 1 - 40-50 ft/lbs
stage 2 - 95
stage 3 - 115

available range 90-120 ft/lbs

The chart also lists tightening patterns. If you do your own tire changes, you should be familiar with these procedures.

Also, you can keep the tire guy honest too!

A torque wrench is a must have when working on trailers.
