So to begin, I have a 2000 blazer 4WD. I have replaced the front end shocks, wheel bearings and idle arms.

I will begin my problems with squeaking. My truck squeaks whenever I go over a bump or any type of uneven pavement. My truck also rocks back and forth ridiculously bad, going over bumps or uneven pavement. Also, since I live on a dirt road that becomes pothole central, I will also mention that my daughter and I almost died about 10 minutes ago from going over a large pothole. My truck literally jumped to the other side of the road, and I thought for sure we were going to die. Thankfully, I recovered well enough to not have an accident, but it was quite scary. When I slid from going over the pothole it reminded me of going over some black ice, where it felt that you suddenly lost all control of the truck and it jumped to the other side of the road. Any ideas as to what is going on? I thought that when I replaced the shocks that that would take care of these things, but apparently not.

Secondly, and my main concern is that I feel/hear knocking underneath my driver side floor board while driving. The knocking began when I went over uneven parts of the road, I would hear a loud clunk from my tire. Now, it has begun knocking while Im driving around a curve or a turn. Whenever I turn my wheel a bit to the right, at one certain spot, I will feel and hear a continuous knocking underneath my floorboard. (As well as going over those spots on the road that have a mile long stretch of poorly filled potholes) At first I thought this was from my sway bar links being bad, but my husband checked them and said that they seemed fine and stable (although he did mention that the sway bar bushings were rusted and looked like they need to be replaced) Any ideas?

Anything you can think of that would cause these problems will help me a great deal. Im very paranoid about driving this truck, because its had so many very unsafe problems, so I am a worry wort about whats going on, basically so I know what my chances are of death resulting from driving this thing. Thanks

 

Well definitley if it feels that unstable, and making all kinds of noises, first thing that should be done, is the truck jacked up under the lower control arms, and wiggle the wheel/tire side to side, and up and down and see were the wear is. if you find that it feels loose, find the part thats moving. possiblilitys are upper/lower ball joints. inner/outer tie rod ends. control arm bushings, etc. i am not going to say your going to die driving it, but if you hit a pot hole and it bounced across the road, i would definitley say chances are high lol. some shops offer free inspections, call around and see if one in your area would look at it for you..

 

Check your sway bar links and make sure there is no movement in them. If they are bad you will hear alot of noise when hitting bumps and the vehicle will lean slightly in turns.
