Hey Guys,
The ball joints in my rear lateral arms were loose, i think it accelerated bearing failure as well. I have a non-pp and purchased the PP arms. The PP arms are cast vs welded steel like non-pp and are direct fit. I'll post a picture of them side by side later.
Part numbers for reference:
PP - DE9Z-5A972-C
Non-PP - DG1Z-5A972-B
Oh cool. More good PP swap out parts.
