Resonating Noise at 30mph

[bhults]

I just installed my double add-a-leaves this weekend, with warrior shackles. I noticed today that while driving between 30-34 MPH, I get this resonating sound thru the cabin...once I'm above 34 MPH it's gone. Below 30 and it's not there. If I stay between these speeds, the noise stays. I assume it's a result of the changes I made out back....I'm ready to order up my tires, so I wanna isolate/correct this 'problem' now....any ideas?

Make sure everything is tight (torqued to specifications). Depending on the size of the u-bolts, they should be anywhere from 65 (1/2") to 90 (9/16") lbs./ft.

I was just reading some threads about tq/specs for various bolts, etc., and read that stuff should be tightened and retightend day after day till the specs level out and nothing loosens. That might be the culprit right there. I haven't retightened anything since Sunday.

Retorqued everything last night when I got home from work, and alas, no more noise. I'll keep this up for a few days till everything settles...thanks for the suggestions.
