66 c10 lower control arm bushings

[Chevy nutcase]

Decided to dig into remove and clean up my upper and lower control arms as they are one of the last things I haven't touched yet. Bushings weren't sloppy or loose but after removing them I noticed the threads on the bushings and corresponding threads in the control arm weren't looking so hot. The bushings are no biggie but im wondering if the arm itself is shot

I think as long as the shafts are straight and the new bushings thread all the way in and tighten (some are very tight before they even get close to seating), that the arms are ok to use. Pay attention to how the threads start and how many turns you get on each one so that you end up with the shafts in the center of the arm.

I mark mine and turn each one the same amount of turns when installing them .The threads look ok to me

I thought the same thing when I took mine apart. I think yours looks better than mine. I was able to replace both upper and lower bushings and able to torque each to 100 ft pounds. The manual shows different torque specks for "new" or "replacement" bushings. I read a couple threads on here about the difference and I wasn't sure of the exact conclusion. I went with the 100 ft pounds. I think the other is somewhere in the range of 180. I marked each shaft with tape, found the center and marked the tape. As others said, I tried to tighten each side equally and continue to check as I went. I think I got close. I might be off by a 1/16th on one of my lower control arms and hope that won't be a problem.
One thing I did do is a tried each cap into each control arm and shaft to see if there was any fit difference. There were actually a couple that threaded into the shaft/control arm better in certain places. I think that might have been a little bit of over kill, but I figured it couldn't hurt. So, I marked which ones fit where better and then greased and assembled.
