I have tried my best and an I can't get a socket on the bolts holding the rear wheel hub...... Do I have to remove the upper control arm? Will that give the axle any play so I can get a bolt on? I tried without removing the upper control arm, because I didn't have the part necessary to remove. Does removing it give me any additional play to change the wheel hub? Please help..... I didn't think anything could be more challenging then my DeVille and DTS, but the STS has topped it!
