tighten the shit outta them then tourque them to 150ft/lbs, thats what i did on my 8.8 and they havent loosened yet, 3 years,

What thread is on the u bolts and what grade nut? All you need is a torque chart.

should be 9/16 we go till our gun stop's and thats 350 lbs ... just remeber they are streach nuts and need to be retourqued allways at least once

i tightened up to 110 foot lbs which is what the book calls for but i thought it was a bit on the low side. how much gear oil does the rear end hold 2 litres?

at my work you tighten them as tight as a 1/2" impact will turn em....
