leaf spring torq

[1970mule]

what are the torq specs on the u-bolts on the leaf springs and the eye bolts as well? thx

don't know what ones you're using, but i installed a set of WH's extreme a few weeks ago and they recomended 100 ft lbs.

well i have the WH but just the regular duty ubolts. ok thx

100 ft lbs is fine and recheck them after driving about 100 miles

x2 on the recheck as mine loosend up a little after awhile.

 

[BIGED]

X3 on checking them after you drive them a few times.

is there a pattern i need to follow when tightening ?

No pattern, but, as with any u-bolt, it's important to take up evenly on both sides of the u-bolt. I've even used a ruler to measure how much bolt is past the nut as I'm tightening them.

I would have said more like 65 to 75 for the standard duty ones. I think that's even what WH recommends for them. We had a discussion about it a few months ago. Might do a search, or call them in the morning to make sure.

Extreme duty ones are larger diameter and come with heavy top flanges don't they Stallion?
Are the standard ones 1/2" 1970mule? Or could they be even smaller, at 7/16"? Probably 1/2, but thought I'd ask, since if they're just 7/16 that 100 lb would definitely be a bit high.

yes i beleive they are 7/16 so i think 75-80 ft/lb is right.

 

[73stallion]

stock U bolts would be ½"

the WH plates are about ½" thick, and the U bolts are 5/8" diameter.

stock U bolts would be ½"

Mine might have had 1/2" threads, but the shanks were necked down noticeably less than the 1/2" replacements I used.
And, I broke three out of four just trying to get them off the first time. It was interesting to watch the shanks twist as I tried to remove the nuts. Went back and forth a couple of times and then, snapp-o!
Real potential knuckle-busters they were.
Went to 1/2" aftermarket (Ranchos) the first go-round, then up to 9/16" the last time. World of difference.

the WH plates are about ½" thick, and the U bolts are 5/8" diameter.

Nice. Now that's what I'm talkin' about when I say: "With some things, there's no such thing as overkill."

thanks

I stripped out a few 1/2" ones at factory torque specs. I now torque them often at 65ftlbs
