control arm bushings???

Hey guys and gals.....Just curious how many people on here have had problems with the front bushings on their lower control arms??? I had mine up on a lift checking all the suspension and found that they were completely broken. I also found that they were the source of alot of noise over bumps. maybe you should check them out. I have a 2000 impala LS with about 135k
miles on it. just let me know.
