Whenever I turn into drive ways or slow turns the steering makes an audible and disturbing creaking, like an old wood floor. Mainly happens going up an incline slowly or being stationary and turning the wheel VERY slowly. I already checked extensively for frame cracking around the steering box and it is perfectly fine. Is this all due to old and worn out bushings and steering linkage? That's what I'm leaning towards replacing to fix this. I also have a bad vibration that kicks in hard around 90 mph and gets scary bad up around 110-120mph. The only reason I went that fast is to see if it got worse because I also experience it mildly around 45-60 and then it goes away until the higher speeds, and is really only bad in OD. Could this also be a result of the crapped out steering linkage and front suspension in general? If not I've heard that a transmission mount would be the next thing to check and if it's not that, possibly the drive shaft. Thanks for any advice guys, this problem is taking some enjoyment out of driving.

 

Quite possibly ball joints. When they get loose, they tend to make popping and kind of clunking noises. Full front end rebuild is probably advisable if the car has alot of miles.

To check if it's tie rods, jack the front end up and try to rock the wheel back and forth in the direction it would turn if you turned the steering wheel. Just put your hands on the left and right edges and try to turn the wheel that way. If there's play, the tie rod ends are probably bad (or any of the other wearable parts).

To check for ball joints/wheel bearings, try to rock the wheel vertically by putting your hands on the top and bottom. If the wheel can move in and out, either the wheel bearings or ball joints are bad.
