I ran across some information stating that the factory torque spec of 90 ft lbs for the u-bolts to spring plates will actually bend the the factory plates.
I'm trying to determine if this was a one-off or I should be torquing significantly less for the u-bolts.
So then I gather most people are not torquing to specifications or the lift kits that are all so common purchases with these Jeeps have alternate specifications for torque.
Anyway I guess I will err on the side of caution and torque to 70-80 ft lbs.
I put my air-wrench on 2, of 1-2-3. I've done that with lots of 3/4" nuts (lugs too) for 30 yrs. I only use my torque wrench for head bolts, important things that compress a gasket.
Same as above. Anything with a gasket or RTV, anything on something precise, and anything that needs to be even. Keep in mind that OEM u bolt nuts appear to be regular nuts, and some replacements use nylon locknuts. This changes the torque value. What's important is that the tightness is even. I also use the redneck torque settings on my impact.
I'm SOA. 90lb tq sounds right. I think I re torqued once after install. Spring plate has not bent. Zero problems. It's been like this for years on my Jeep. If the plate is bending it could be due to rust?
My lift kit came with new plates [ much thicker ] and larger U-bolts and said to TQ. to 90Lbs.
