Lower control arm pivot shaft woes

I did have the thick washer under the nut. There did seem to be some oil or grease on the back side of the shaft. I may have messed up in that I was tightening the nut with no load on the t-bar, car was on jack stands. Thanks for responding, guess I need to take it all back apart tomorrow

Bob.

Or mabe try a little sideways pressure on the control arm (up, down, in, or out)
Whatever you can do to increase the resistance on the pin turning.
It's def worth a try.

Personally, I would put a small jack under the pivot point and put a little pressure on it to see if it would hold till the nut pulled in down tight.
