Hi I just put is a new steering rack and have two problems The sway bar bushimgs have a steel washer behind them, I assume to hold the rubber bushing in so they do not slide out. I have some space behind them and the bushing work their way out. Do these washers slide on the sway bar and do I just have to slide them back into place or is there a part missing. I am also getting a noise from the front right assembly when I go over bumps at low speed. This just started after the rack change. The rack is thght, the noise does not seam like it is coming form the rack.
