I currently have my car about 20 inches in the air ready to attack. Here's my issue. I have a groan from the drivetrain (seems like). It's not noticable until over 65 then it progressively get's worse. If i'm going 100 and slow down I get this nasty shudder. I was thinking u-joints but they seem ok. I really don't want to drop the shaft unless I HAVE to. I do have a 93 1pc aluminum waiting to go in. All the bushings look intact. My steering wheel also moves left to right for no apparent reason but everything up front looks ok. Could a wheel bearing be to cause and just droning though the car?
I've done all the normal checks and everything seems ok. I'm about ready to drop this thing off a cliff or sell it soon if I can't figure this out. And getting smoked by a 93 S10 didn't help me either.
check front camber bolts. tighten them to 105ft/lb. if you have a 1 pc aluminum shaft, why not go ahead and put it on. that way if it is u joints, problem fixed. if not it's one more thing off the list to check.
