Ok The poly bushing make a bit more noise than the stock set up but thats the nature of the beast (poly makes noise). Figured out my problem which once fixed, seriously improved the situation. I bought some bfg's from the toyota dealearship (believe it or not they were the cheapest around) and when they installed them they decided to tighten the rear shocks were they mount to the frame (top). They tightened them down so tight that they actually pushed the bushing out over the retaining washers.
So my shocks were bouncing around and started making the rear end rebound wierd. Overland Warehouse was great and sent me new ones right away I tightened them down properly and everythings great. Really really like OW. The dealearship service dept. can

friggin morons.
