Think I can add an adjustable link to these control arms?

think i can cut these an ad an adjustable link. start my own brand. machine a treaded insert on one side to thread in an weld nut on other end of control arm, an throw a pin in a hole drilled to double secure the treaded side into the other side? anybody know what kind these are? procomp shocks were on it, an the oem bushings fit in these, same size.

I dont think these bushings need changed, there stiff, can move em at all with putting a long punch in the center. dont change em out right?
 
Stock arms are actually preferable to those. Rubber bushings by themselves do not have enough misalignment for the suspension to articulate. You risk tearing off a control arm mount. Stock arms, with their "C channel" design are designed to twist beyond what the bushings are capable of doing.

If you need adjustables to correct pinion angles and caster, use ones with flex joints with high misalignment like a Johnny Joint.

X2 to this. Exactly what I would have said.
 
If you feel like you’re a skilled enough welder / engineer, then yeah, you can make your own adjustable control arms. I wouldn’t start with those ones though, the joints on them aren’t any good.
 
Okay. Lets just say, I cut the front joint off, an add a adjustable johhny joint to it, an leave the rubber joint on the back, seeing that the johhny joint is like 50 a piece. would that give it enough flex. johhny joint on front/rubber oem on back? I was watching this video of people strengthing the stock arms to take out the flex?. so they shouldn't be doing it if they are using the jeep to rock climb/flex etc, unless they cracked em before? thanks

I single JJ works. Most of the misalignment will be handled by the JJ rather than both ends.

Those who box in their factory control arms are not understanding the function of the factory design. They risk tearing off a mount or snapping an arm in half.

That could work, but if he's really hitting his arms on that much stuff that's causing them to bend, he needs to get aftermarket arms and be done with it. Perhaps it's a money issue, but it never hurt anyone to save money.
 
Not positive I fully understand what you are trying to do, but it looks like this. If so, it might be worth it to just save for a bit and buy them?

ya, just like that. cut the one end off, machine up an insert,with same threads, weld it in around the tube, with the collar being same size as tube, an screw in a JJ. as a matter of fact. couldnt you take a oem control arm, cut the end off, slide up a square threaded box to fit on the end, weld it in an ad the JJ to it? ya, savin ups cool, but something to talk about being chased by a bear.........cut that off, machined up a collar, weldherd in there, an screwed in a JJ, an saved a part of the po's dream.........an powerder coat em up ruby rud.........:)

You probably could but by the time you buy all of the jj you want to weld on it is probably cheap enough just to buy one already done the way you want it. You won't be saving that much money doing it yourself. This way someone has it done perfect, and you can count on it working.

For instance on yours you will have to change your rubber bushing and buy a JJ and probably by a giant Tap and Die by the time you do that these core ca's are probably cheaper and ready to install.

update to drawing..

Nice drawing, I get what you are trying to do. And you can probably get away with it if you want, but I would worry about the strength of the stock arm especially when you bore into it and weld onto it. I don't think you can do it that much cheaper than core, but like you i have a desire to build my own things too. I don't really see what your gain is here, but more power to you if you want to build it yourself.

You had me with, " You probably could"..........weldednut goes running out the room........to go borrow a tap an to buy some perfection in a bag........:) an now i got that song in my head....in a bag....what is that song...??? oh i got it .......an it says " i am good at repairs" in the lyrics...how bout that.:)

Thanks ac:)

ya i wouldnt do it with the stock arms, at this point, but these aftermarket ones i got. i think drizit, just made it very easy:)
 
I did this today to prepare me for this control arm project..........shredder in a bag, in a can..........patent pending:)when your tired of m/t ing the shredder all the time.......the shredder would be the jj or the heim, the wood the insert, an the can the cut off control arm:)
