Torque for Axle-Spring U-Bolts?

[wdk450]

Gang:
I went all through the online manuals, through my copy of the Lippert Axles manual, did a search on the forum on "U-Bolts" and "Torque" (It didn't help that "Torque" is a Heartland Model), and didn't find the torque spec for my 2008 Bighorn with Lippert Axles for the spring-axle U-bolt nuts. I think that this is something that is supposed to be checked on a regular basis, so that info SHOULD be readily available.

Maybe a torque specs table would be a good addition to the online "Manuals" section under the "Tools" tab.

U bolts are grade 5 spec,if your u bolts are 1/2 inch then the torque will be between 70 and 80 ft lbs..
if 9 /16 u bolts then it will be 80 to 90 ft lbs. do not overtighten your u bolts-you will stretch the threads if you over torque and they they will come loose,possibly allowing your spring to move out of place.
This is the info I received from Dexter when I replaced my springs.

Thanks for the info. Was this posted in the Heartland Owners Forum somewhere?

Bill,

It's in the Lippert Master Towable Manual in the Manufactuer Collections folder. The content is so broad that it really doesn't fit in any other category.

I started through the "Lippert Master Towable" document in our "Tools, Manuals" section, and thought I was reading the Lippert axles manual (again) that I already have printed out.

Thanks for the help!!!

When installing new u-bolts, first torque and then pound on them with a 3 lb. hammer around the radius where they wrap around the axle after then re-torque. Re-torque again after first trip as they will "settle in" and usually loosen up a bit.

Thanks for that advice. I am now about 600 miles North and have some free time to check this.
