Have front end squeaking that is just about intolerable now

Customer Question

Have front end squeaking that is just about intolerable now in my 2002 gmc sierra. Replaced ball joints a couple of years ago. Have greased all points every month. Squeaking has been going on 'n' off for about 9 months and as I stated is beyond belief now. Help please

If everything is greased and the upper and lower control arm bushings look good the next step, which I have seen many, many times and GM issued a service bulletin for is the shock absorber insulator. I'll post the TSB and procedure below. The insulator can be found at the link below
