After installing new rsr springs and the tokico 5way adj. shocks, new stock upper mount, and the rubber piece that goes between the bottom of the springs and the shock, my passanger side rear suspension makes spring noise when the suspension moves. What could be the cause? I've taken it out and reassembled it but it still makes that same spring noise. Any solution to this problem?

 

after market springs/shocks were not built to supress noise and make a quiet comfertable ride. All it is, is just noise, i wouldn't be worried. after market springs/shocks/coilovers are made mostly out of metal rather than metal/rubber/otherstuff like stock suspensions are.

 

it might just need to settle in. drive it a while see if the noise stops.
