Passenger Side Lower Control Arm With Torsion Bar to Make Bushing Tight Again
 These blasted lower command arm bushings! #48245 11/26/07 08:44 PM 11/26/07 08:44 PM | |
| Anonymous OP Unregistered | Today at work I tried removing one of my LCA bushing shells. I think I did more than harm than good. What I did was, I took an air hammer with a chip that my coworker made for removing bushings on the cars we work on. Merely the bushings it is unremarkably used for can be pushed right out from one side to the other, non like on our mopars. S o I used it to collapse the wall of the bushing inward, all around. Then I took a long, blunt chisel scrap and went through the torsion bar hole to hammer at the folded in portion. THis really pushed the sleeve out about 1/4 inch, but then broke the piece o f the shell I was hammering. So I tried to fold in some other portion to hammer against, and doing and so pushed the bushing dorsum in. In the prosess of trying this again and again I accidentally cutting a couplle shallow gouges into the bushing recieving expanse. So I just gave up so I could get my caput back on directly. Tomorrow I'm going to have my air saw to work and try to cut the vanquish in 2 places so it will collapse in on itself. This should work, I think. BUT just to analyze, the control arm will exist fine once I get the shell out if I only use a die grinder to clean up the burrs right? At that place's still plenty of area left to agree the bushing, information technology is just a few small gouges. 1 thing I noticed is how flimsy these arms are. When clamped lightly in a vice the portion where the torsion bar attaches no longer spins freely from the arm flexing. I assume that is normal and will not pose an issue. |

what he said. If you don't have a welder or don't want to buy the tool for removing the outer beat - Brand a cut down the inside of the bushing most through the outer vanquish, and then "skin" the bushing toward the inside with a small chisel or drift pin.| Re: These blasted lower command arm bushings!

I don't have acess to a welder, merely I volition endeavor cut it and so it tin plummet on itself and loose it's grip. But, every bit long equally I smooth out the pigsty with a die grinder and the new bushing fits snug, it should be find right? |

And then I decided to put rubber. But when I removed the arms I notived the Grand Fellow member was broken. In whatever example, I wasnt things as tight as possible, so I am going dorsum to condom.

Heck, they themselves are only held in position with snap rings. I don't know exactly how much front to dorsum load in that location is on the LCA'southward, but I adopt the press fit of the rubber bushing and steel sleve over the sloppy, drop in poly bushing. |

| Anonymous OP Unregistered | Ok I got them out. For the one I hadn;t attempted yet, it came out real like shooting fish in a barrel. I fabricated a cut most of the fashion through the sleeve with my air saw, then used an air hammer to fold the bushing in on itself and it came right out. The other 1 took some fighting, just I got information technology out. I cleaned up the gouges with a die grinder/file. Information technology feels pretty polish now afterward, I recollect it'south ok. I asked the owher of the shop next door to mine if it looked ok, and he said I should put 2 "swedish dimples" in the bushing surface area by gently hitting a punch in the side to make a slight raised area to make sure the bushing does not spin, then use locltite. But then with the loctite the bushing is NEVER comming out. Does this sound like a good plan? The pins were fairly easy to get the sleeves off of. I was able to grind a pocket-sized indent in the sleeve, so air hammer confronting the indent and it popped right off of one of them. On the other ane, I couldn't make it budge then I cutting it lenthwwise with a cut off wheel, carve up information technology and knocked information technology off. Merely in the procedure I cut a hair tood eep and made a very shallow ut into the pin itself, maybe as deep as a fingernail. Everyone seems to think it won't be a problem. Audio right? Lastly, I loked and as best I can tell the artillery are straight. Just gotta push button the bushing in, then paint them. One call up I was wondering, do I button the bushing into the arm, then the pin into the bushing, or the other fashion effectually? To press the pin in practise I need a sleeve that volition fit over it to press on that shoulder at the bottom, or can I press on the end of the pin (by the threads)? |

| Anonymous OP Unregistered | I pressed the lowers in today. I put some loctite just to be condom, just information technology took between 4 and seven tons of pressure level, and so I remember they'll hold But, I screwed upwardly again... It'south like everything is going wrong on me. I had some trouble setting the uppers in the printing, I got ane bushing in each, but the second bushing got cocked in the printing and destroyed the bushing. So now I'chiliad out a set o $30 MOOG 7103s... And when it got cocked it bent the outer edge of the bushing recieving area slightly. Not plenty that I call back it will be a trouble though. I recall I can just wack it with a hammer to ready the slight curve (it is like egg shapoed on the very edge) then maybe put a dimple in the inside and printing the bushings in with loctite mayhap. I think that should hold, because in that location is even so plenty of paterial to printing into ahead of the curve. Whatcha call up? Will I exist ok? I tin can't believe I proceed screwing stuff up. I gotta stop rushing.. luckily a local parts store has them in stock. $v more than I paid at rockauto, but will be faster. |

| Anonymous OP Unregistered | Ok the bushings are all in and the arms are being painted I didn't make whatsoever dimples or utilise loctite on the new ones. I figured I'd effort information technology and meet how tight they are before doing anything else. I put them in with a hammer 9put a piece of pipe over information technology then I would just load the edge of the shell, and hammer away) and let me tell you, tehy are in there TIGHT. My arms feel like jello. I remember the slight egg shape fabricated them tighter. Simply affair now is those large washers (ferrels I think?) that need to exist pressed into the ends of the bushings, on one of them (an outer one) the errel doesn't stay in, it slips right in and can exist pulled out. I don't think this volition exist a problem though, equally those only transfer the load into the sleeve, and will be held in constant compression in one case the cam bolts are tightened anyhow, right? |

Weld a bead around each tube and grind it so the LCA pin sits flush with the tube. That's a very mutual problem on Mopar yard frames. Check the weld where it exits the from of the Chiliad, too. I've seen holes around the tube in the front where the assembly line weldor/idiot used also much heat and blew a pigsty in the K frame and never filled it. |

I change bushings with the afformentioned tool kit without a press in a very short time on the bench. I feel that if in that location is any place in the pause that can utilise a hard durometer bushing, its the LCA. This signal gets hammered in no time with rubber bushings. Even though the bushing is thin, in that location is enough deflection to change the camber. I am pretty anal when information technology comes to alignments, considering information technology can make or break a good suspension setup. I feel that putting rubber bushings dorsum in is a complete waste of time and effort. |

There tin can be a variation in thickness per different LCA bushing replacement manufactures. As well, when they are pressed in/on they can buckle a lilliputian causing a diameter variation. Earlier Energy Intermission got large, Guldstrand Applied science (Vette/GM suspension specialists) sold just the poly inserts made to thier durometer specs. But they told me when energy came along and included the shells they just sold the Energy stuff. They explained the issues I re-told above with the erstwhile bushing shells and were tired of the fitment headaches that would popular up. I had to carefully die grind the outer shells and then sandpaper scrool them smooth. I fifty-fifty tried to vitrify them a petty. I besides used a real fine safety impregnated grinding wheel to grind the inner pivot sleeve so ran it on a buffer. Also advisedly ground only a piffling off the outside of the poly bushing. My theory was if the begetting surfaces were smooth they might not squeak. I've ran about 25K miles on that setup and never relubed them. Doesn't squeak.
