My 2002 'Burban LT 4wd has been wandering all over the road for a while now. Checked out the front suspension and steering, ended up replacing the pittman arm, idler arm, and idler arm bracket. All the other ball joints, tie rods, etc. ok. Had it re-aligned. Got better, but not 100% fixed. Tires were shot, put new ones on, got better, but still not 100% fixed.

Now I'm thinking of replacing the rear suspension bushings. Anybody out there done that? Need any special tools? How hard is it? ("that's what she said")

Or if you have any other ideas on what could be the problem... please let me know...
