Besides the bushings, excess U bolt torque can cause squeaks. Had that problem myself after assembling MP XHD springs.
Required torque is pretty low, 45 ft lb from memory. Too much will bind up the spring and case squeaks. Loosen and re-torque fixed mine.
Thanks AHY - I had no idea.  And coincidently, the guys around the garage call me "Ted Torque" because I'm always pushing that ratchet like nobodies business when I'm tightening things up. This could very easily be a contributing factor to my squeaking! Thanks!
