Torque on rear u-bolts?

Leafs (OME) and u-bolt flip (wheeler's) are ready to go back in the truck. Once that's done I can do the front.

The factory torque spec is 37 ft. lbs. Is it the same for aftermarket u-bolts?

Thank you in advance.

 

Factory spec is wrong

Do 73ft/lbs

 

Found it and thank you @whatstcp

Woke up stupid early and did some searching:

No problem man, you need more sleep rhough. Way too early

 

I think the wheeler's instructions call for 90ft lbs, Mine did a few years ago.
I re-torqued them again 100 miles later and they did loosen up some.

 

Pretty sure Toyota put out info on this regarding someone reversing the numbers on TIS. I always do 90, recheck later to 100 torquing in a kriss cross X pattern to keep it even

 

Check them weekly until you know they don't rotate any more. It isn't a one and done or two and done operation. I was surprised. Ended up going to 100.

 

When in doubt follow one of many general torque guides. These are max specs, and for dry threads; if you lube with antiseize, or even spit, decrease by 10-15%..

always done ~ 75 ftlbs on mine.

 

Right now they are at 73, still have to install the extended brake lines and OR gas tank straps.
I finally have a use for the trip odometer. A will be for the rear (100 miles) and B will be for the front (500 miles).

 

Torqued the u-bolts to 73 ft. lbs.
Did not install the gas tank straps.

 

I just had my leaf springs replaced by the dealer for a recall. I checked their work after bringing the truck home. They are still torquing the u-bolts to 37 lbs. Some of them had evidently loosened during the 20 mile drive home and were barely about 30. I'm glad the axle stayed on coming home.
