I want to install urethane buushings on my rear swaybar but heard they are noisy. Is this true? Also my belts squeal terrible above 5kRPM. I bought autozone toothed belts but noticed the belts that were on there were the the smooth type. Should I go to the dealer and buy the replacement belts? They definitely aren't loose so I don't think thats the problem.

 

I installed them on my rear bar, and don't hear any noise from them. My fuel pump (Holley Blue) is pretty loud though.
