I have a 2017 Bighorn 3575 EL. I do not ave the Lippert axle book. The book I do have states I should read the axle book. I don't know how tight my lugs need to be once I put the wheel back on. I am guessing 125 foot-pounds, but I am not sure.Any ideas?THanks,John

for MY 9/16 x 18, i have always done 140-- WITH ALUMINUM WHEELSHere is something else I found - clicky

Here's a link to Heartland RV. If you click on the PDF version of the owners manual you will find your specs. Link

9/16" can be torqued to 150# with washer type lug nuts and 130# for tapered.

How tight are the lugs? Repacking bearings. | Good Sam Community

130# is what I go with.

I hope the factory didn't ruin mine.
I checked my new fw last week, and they were torqued to 170ft. lbs., I had to get a pipe to extend my breaker bar to loosen them to 120 ft.lbs.

From the link above, I read that 120 to 130 is what I should torque them to. Since my wrench was already set at 125, I went with it.

Thanks guys.

FYI, you should always unload your torque wrench after using it....bring the setting back down to near zero....to keep it in calibration. I ruined my first one that way.
