I didnt remove my torsion bars, just raised the truck and dropped the LCA until all tension was off. Then moved the LCA forward (theoretically, I ended upp cutting away mine), but the installation of the new one went fairly easy with the bars in place.parts came in last week order it on Thursdays afternoon came in Friday Moring
question do i need to take off both torsion bars ??? or can i get away with just taking one out ???
The ball joint bolts on. They're EASY to change. I don't know why you'd replace new ball joints with different new ball joints, when you could use the ball joints that came on the arm until they wore-out, and THEN change them easily, years from now.I have a new tool in the collection (bushing press) and the Astro LCA is in place. Thanks for the help and inputs.
But for future reference.
I bought RK641493 and RK641492 ULTRA-POWER from rock auto.
The reason I picked those was that on the picture the ball joint was bolted on, and I wanted to change it.
Using the bushing press is a fine idea for cramming the bushing fully into the arms.Three of four bushings was not pressed in enough on my control arms. Easy fix if you have the tools.
The ball joints that was on it did not impress (but might be good, what do I know). The boot fell of before I picked it out of the box?
Isnt it standard with retainer clip or something?
But now they are on and I can start swearing over other things!

First Guess: They saved the cost of four rivets, and the press-in ball joint is simpler and easier (cheaper) to make.Why did GM convert to press in lower ball joints? Anyone? Was there flex in bolt on design?
Good point, with the ball joints. I had already bought new ball joints before realizing I was changing the LCA as well. So thats why I thought about changing. But Ill think about it.The ball joint bolts on. They're EASY to change. I don't know why you'd replace new ball joints with different new ball joints, when you could use the ball joints that came on the arm until they wore-out, and THEN change them easily, years from now.
HOWEVER, your photo shows that you're not supporting the structure of the arm while applying pressure to the bushing. You're lucky you didn't crush or distort that arm. There should be a half-round support sleeve as a "special tool" around the outside of the bushing, to prevent the arm from collapsing as the pressure is applied.
im still lost/ confused on how yall took off the lca without taking off both torsion bars
