I need to replace a number of piece on my front end - upper and lower ball joionts, tie rods, drag link, ... This is a daily driver car and sees some rough country about 2x a year for perspective.
1 Is going with a complete package a bad idea - like the following https://www.1aauto.com/jeep-cherokee...EaAjduEALw_wcB

2. Are there some more critical parts that one would say defintely buy X in heavy duty form?

I normally buy from AutoZone (AZ)

I know that is open enede but over the last 10 years I have gotten good advice from this site.

 

When I rebuilt my front end last year I bought some individual components and then a package, so I had some duplicate pieces. There was no difference in quality between the individual components and the package. You do save a bit of $ buying the package.

 

One thing you didn't mention is the track bar. If that other stuff is worn out, so is it
