Post Lift Re-Torquing of U-Bolts Question

My lift has been on for 6 months and I've heard of U-bolts stretching a bit and needing to get retorqued, so I here we go.....

They looked pretty seized on there already, so I thought I would back them off and then retorque. Problem is, that after backing them off and then hitting them with the torque wrench they are already at 74 ft/lb. They were certainly not overtorqued originally as I'm pretty fussy about stuff like that.

I've also heard that torque values are "moving torques" meaning that even though I checked all the other ones and they were all at 74 ft/lb, that could just be due to them being seized on?

I thought about giving them a WD-40 hose down, but wouldn't lube affect the torque too?

Thing is, everyone here gets used to how their truck feels on the road, and maybe I have gotten used to a truck that has U-bolts that need a little snugging up. I dunno.

Any thoughts or suggestions out there?

 

Thanks for the suggestion, I'll give it a shot next time my driveway is dry. Maybe they didn't need tightening at all anyways? After lifting my Tacoma I checked the U-Bolts every two weeks for a couple of month and none of them were loosened at all.
