So when I was under the truck on my last off time, I replaced the failed bump stops. I did notice that the swaybar bushings were on their way out. I ordered a set Part #3.5213R (Replace R with B if you want the black). This is for a 04 GMC 2500HD 2WD. The difference in handling is night and day. The handling and response is much better. Sorry, I rotated this flipping photo several times and it still doesn't show up right.
