Rear axle U-bolts torque specs?
Does anyone know what the torque specs are for the rear axle u-bolts? This is for a truck with trailing arms and the two big u-bolts. I did a search but couldn't find anything...

I did some more searching and think I found the answer which is 145 ft/lbs. Sounds good to me!

Re: Rear axle U-bolts torque specs?
I don't think I can pull my bar that much.
Maybe I need a 4 foot bar. 320 divided by 4 = 80. I can do that.

Re: Rear axle U-bolts torque specs?
I actually bought a new torque wrench for doing these (and stuff on my big Dodge Ram truck). I did 220 ft. lbs. My new torque wrench goes to 250. It was hard to get it to click at 220. LOL

Re: Rear axle U-bolts torque specs?
you have a range of 100. maybe it's given for new/used u bolt. the lower will be used and the higher will be for new, as it's lenghtening it when you torque it?

Re: Rear axle U-bolts torque specs?
yep your body might slide on the floor under your arm power with this kind of torque on a short wrench!

Not sure if this will help on chassis torque specs:
