72 C10 highlander

[Eightball1978]

What's up,
My name is Asa, I've found forum while looking for ideas to figure out causes of problems I've had in past. I learned to drive in a 72 C10 that belonged to my grandparents. When I was 18 I got a 69 and every since then I've never been a whole year without having a 67-72 C10 I've had 18. 73-80 I've had about 14. The truck I have now is a 72 LWB Highlander optionThat I bought to replace the one I learned to drive in after it was stolen and carried to scrapyard. I arrived to late and in Alabama after so many years you don't need title.
My problem is a popping sound in front steering, before I replaced pitman arm you could see the center link hitting cross member when truck lurches forward when coming out of park or reverse to drive. I've replaced pitman, idler,2 TRE (both inner) the tie rods were all practically new. After putting truck together steering was a lot better but I'm still getting a pop I have no idea what it is I do know ball joints are tight and the center link isn't moving it's driving me crazy.
