Re: chuck the fresh u-bolts for spring replacement?
There is a good rule of thumb that applies to u-bolts real well. First, toque them to 30 ft.lbs , then to 60 ft.lbs. as evenly as possible . It's difficult to keep them tight against the spring pad, but with some work or a clamp it can be done . You just want them straight as possible . Do the first torque step on one side , then the other side of the axle . This keeps everything nice and straight . Once the bolts are torqued, here's the rule: Torque the first day , re-torque the next day (after some miles of course) , re-torque after one week , and again after a month . This will keep up with bolt stretch , and ensure that all of them are even . Good luck,
