Page 60 in the Escape Trailer Owner's Manual? What the what?!?

Our vintage 2013 owner's manual -- weighing in at a whopping 22 pages -- states that torque should be "90-120 foot pounds". That's quite a spread. Sounds like ETI's advice has gotten a bit more specific.

Don't see the 2014 owners manual in the files directory above, if you want it pm me your email address and I can beam it to you.

Thanks for the offer. It's on the ETI website.

While checking around the forum for some clarification on torque for aluminum wheels (it seems to vary from trailer sticker to manual to verbal orientation instruction) I came across this opinion on loosening your nuts before you re-torque them. A few people objected that this did not make sense, but not really strongly enough. Time for a disclaimer: I'm not a mechanic so my advice is my experienced opinion only. A real licensed mechanic or engineer should weigh in on this. Never loosen your lug nuts before you re-tighten them unless you plan on checking your lug nuts every 60 miles (like every hour during the trip). The only times you should loosen your lug nuts is when you suspect they have been over-torqued or when you are removing the wheel.

My experience with 2 trailers, both with aluminum wheels were that the factory wheels could not be made any tighter than what they were from the factory, after 500 to10,000 miles. That said, recent new tire/bearing local service, after 100 miles needed further tightening.

Most of the torque for tightening a bolt is to overcome the friction between the nut face and the wheel, somewhat less to overcome the friction between the nut and bolt threads, and the smallest amount to stretch the bolt - the total is called the preload on the fastener. Ideally it should stay within the elastic range of the bolt material so the bolt does not permanently stretch, which would eventually lead to bolt failure. I don't see any advantage to loosening the nut prior to re-tightening as it's just relaxing the bolt material and then stretching the same bolt again.

Here's a good chart with how the torque is distributed when tightening:

My confusion is that if I am to loosen the bolt before torquing, and I am to check it after a 100 miles, do I loosen the bolts and torque, and if I do that every 100 miles, when do I get home?

Can't fault that logic!

I think this is the point where Alf comes on and says "that now he's really torqued."
