I replaced some old SPCs on my LX back in Feb of this year. Went with new SPCs (xAxis bushings and non-greasable balls). Ever since then…pop, clunk, pop, clunk from driver side UCA. Last weekend I finally tested DS upper ball joint with a dial gauge and found at least .100” of play. Emailed SPC and they immediately responded that for $500 and change core charge, they would warranty claim. Nope, I’m not going down that road again. I’m looking at Dobinsons and Freedom. Haven’t yet made up my mind. Cross my fingers every time I get in the truck to drive on the SPCs.
