whole lot of shakin\' goin\' on I've got some overall vibration in my '87 Blazer. I've replaced all the wheel bearings, put in a new drive shaft, had wheels balanced. No lift, stock ride. It's gotten better but still has vibration. I have yet to check out the shocks which is next on my list. Can bad shocks create an overall vibration? It does seem to subside a bit on smoother roads and worse on rougher ones. It all started after putting on new rear brake drums. Everyone I've talked to says they can't be the culprit. Any ideas?
