I have a front end knock when I first pull away and when I am turning. It's pretty loud knock. I recently replaces the struts, a-arms, and sport line springs. I am about to drive me car back to Michigan from north Carolina and I need to fix the problem before hand. I have the car up on jacks. I don't see anything out of place or loose. Any help would be great! Thanks

 

Does it happen only when your backing out and turning?

 

Yes. I dont have any sound when i am cruising!

 

Try tightening your six K member bolts. They are known to come loose and sometimes even fall out. (So if you have less than 6 then some have already fallen out)

I learned that my self and from others experiences, it only made a creaking/knocking noise when backing out of the drive way and turning the wheel. It never did it while driving forward.

That's just ones suggesting out of many that I could suggest. Have you tried narrowing down the noise and where it comes from?

I would try the k member bolts and if that does not help then there are still a few more possibilities. Just try the easy stuff first.

 

Ok i will give that a shot.

 

Here's a pic from a GM service manual showing the locations.

You can see that the #4 part are the bolts for the one side. The other side is the same.

 

Here's a better pic but without the key:

Edit: Almost forgot, 120 ftlb torque specs.

 

Kmember bolts good!

 

So they were not loose?

If so, Then have you tried checking the whole from suspension? I mean everything from the idler arm, center leak, inner/outer tie rods, ball joints, everything.

Also, This may not even be your problem, but better to check anyways; you may have the common frame crack near the steering box. Here's two pic's:

Ignore the red circle on the first pic, that's circling the rag joint; Look to the top right of the circle, that's the frame crack I'm talking about.
