99 S10 differential shaft vibration

Got a 99 extended cab, extreme stance, with 2011 Camaro 18" Steel Tires on 3" spacers wrapped with 245-45-18 up front and 245-55-18s on rear, V-6 Chevy s10 with about 90k miles on it. I bottomed out on North Bound 101 Fwy just before Santa Barbara. Shortly after on my drive back home to San Fernando, I noticed vibrations when I exceeded 70mph. The problem progressively worsen and now I get vibrations and other squeeks and rattling as a result, but only when I accelerate.
