Lower ball joint premature wear

[Rufton]

66 2WD GMC

Investigating 65+ mph steering vibe.

Both LBJ had approx 1/16" vertical and 1/16" horizontal play.
Neither OEM UBJ had any detectable play.
No detectable PA, IA or tie rod play.
LCA, UCA no play RH, LH TBD.

Funny thing, driver side LBJ was replaced w/ Perfect Circle FA481 LBJ in 2006 (roughly 5,000 to 10,000 miles ago). It never seemed to accept grease right. Grease went in zerc but out bottom seam. Could never get dust boot to balloon. I'd expect factory grease to last longer than a few thousand miles?

Getting ready to pull LH LBJ and UBJ. Already placed order for MOOG UBJ (K6024), LBJ (K6023), TRE (ES370R, ES350L). Already replaced PA (K6086) and IA (Parts Master 13969-07063210)

Goodyear Wrangler tires do have approx 1/8 to 1/4" horizontal and vertical run out.
I wonder if defective tires/rims can wear LBJ that premature?
Maybe the new LBJ was low quality metal?
