I had a wheel off the fifth wheel camper today. It has been a while.

I am running 8 lug hubs with E range tires.

Went through all the literature and as best as I can figure the torque should be 120 ft lbs. I am kinda skiddish about that being correct. Make take one off today and measure the diameter of the lug bolt and look at some charts.

Should I search further or go with the 120?

Thanks

If you are planning on taking one off, measure torque required to break it free for reference.

My generic owners manual says to torque lite towables 50-75 lbs, and all others at 85-95 lbs. I have 6-bolt hubs, and set them at 90 lbs. I do think that the bolt size is the determining factor, as well as wheel style (aluminum or steel). On mine, at 90 lbs, rarely do any loosen, unless wheel has recently been removed.

I would not set mine to 120 ft lbs.

120 seems a bit high, but not by much. I torque mine to 100-110 lb. ft.

This is what I use https://www.etrailer.com/question-93673.html

It is a mystery why the RV manufacturer does not provide this information in an easy to find manner.

Lighter units generally have 1/2" studs, mid-weight have 9/16" studs, while the heavy weights like DRVs use 5/8" studs. If I remember right 120 Ft Lbs is about correct for 9/16" studs.

For what it's worth, I have 5 lugs. Written on a sticker attached to the front of my 5th wheel it says to torque to 100 Ft. Pounds

Life is a lot like a baseball pitch. Sometimes you get a fast ball down the middle of the plate and sometimes you get a curve ball in the dirt.
