Loose suspension help please.

My suspension feels loose as I'm driving down the highway and the front end shakes a smidge at 70 MPH. Replaced many parts but problem is still there. I probably look as if I'm drunk swaying around inside my lane.

Here's what I have replaced so far;
Upper control arms L/R
Upper ball joints OEM L/R
Lower ball joints OEM L/R
Tie rod end links Moog L/R
Rack and pinion

Had alignment done, front tires started feathering on the outside tire, had another alignment done, rotated and balanced tires and the tires are "feathering" yet again.

The front shocks were replaced roughly a few years back and I don't see any "wetness" on or around them.

Any suggestions as to what to load next in my nice shiny parts cannon?

Thanks!

 

Have you checked ower control arm bushings? Also, if you put in a reman rack and pinion check those bushings. I've bought a reman before with shot bushings.

 

Might also try another alignment shop. A good one should be able to tell you what is causing the issue. My shop won't do an alignment if there's anything out of spec because they know I'll want to fix it before spending money on an alignment. Some shops will charge for an alignment knowing it won't align properly.

 

Yup..... I went to Big O tires to get the alignment done. Seemed like I was bothering them for daring to ask for an alignment. They were the only shop around that would get me in the same day.
