I talked to me service rep about the creaking noise I hear coming from the front suspension (after 54,000 miles) and he said that the bushings would probably need to be replaced. (For some inexplicable reason he thinks I'm hard on my T!) I'm planning to take it in and see what it needs, but I'm thinking that if the bushings do need to be replaced, I rather upgrade to tougher after market bushings rather that replace them with the standard GM (minimum quality) again. I figure I'll buy the upgrade bushings just encase they are bad, since I'm sure I'll need them sooner or later (I'm keeping this T until I die and they burry me in it, sorry Alex!). Any suggestions of what bushings I should buy? Also, should I buy the ACDelco 45D2432 Professional Front Lower Control Arm Ball Joint with grease fittings just encase they are bad?
