1997 Chevy Tahoe Front End Stabilizer Bar

I am assuming you are replacing the stabilizer bar. Just remove the old one and put the new one in. There are two bushings attatched to the frame and two bushing kits that attatch the bar to the lower control arm that should be replaced along with a new stabilizer bar. Note--you must remove the plastic round plug that plugs the access hole to the nuts on the lower control arm in order to get access to the lower control arm nut.
BTW--I suggest getting a repair manual.
