I used a press and pushed them out. I know there is a great write up with pics somewhere on another forum, as BlackHarleyMan did a suspension write up in the C4 tech section

Youc an propane torch them out or cut them out. I have cut them out before, then used some emery cloth to get rid of all the minor oieces of rubber left.

A vice and some big sockets or a pipe coupling from a hardware
store make a good press. Its cheap too. |

I was able to do mine with a hammer and vice. Once the center tube is out, the rubber will relax enough to be persuaded out with some mild beating.

yeah, I don't want anymore tools and I don't have a garage, I want to be light and mobile, so the vise is not in the cards, can I coax the center tube out with a knife.

You could probably set the dog bone on a curb or something and hit the center tube with a hammer. Once it is poking out some, some pliers and WD40 will probably get it out.
To be honest though, if you don't have a vice or other basic tools, you might be better off taking the dog bones to a machine shop (or really any shop, most have some kind of bottle jack based press (they can be had at Harbor Freight pretty cheap)) and having them swap the bushings. |

Oh yeah, it is possible to bed the dog bones, so keep that in mind as you whack on it.
Others have had luck drilling holes in the bushing with a 1/4 inch drill bit or so. Eventually, after enough holes, the thing becomes sloppy enough to get out. Do you have a drill? |

I'm revoking your man card for saying you don't want tools. Can't afford tools or have no room for tools; either is an acceptable situation. However, not wanting tools is pretty womanly.
PS- You can get your man card back by posting a picture of a scantily clad hot chick. |

A vise I need, but something i don't want to lug around, it is cheap at harbor freight though, sold my drill press for the same reason. |

I have used a drill, and it works for getting them out. Putting the new ones in may be the problem. If they are a two piece bushing you won't have to worry.

I used a drill and drilled holes the whole way around, then beat them out. Not much beating once the holes are drilled.
The new ones tapped in fairly easily. I greased them up with the lube provided. I went with polygraphite bushings everywhere in the rear, and don't have a single squeak or squeal anywhere. |

Mathew I pulled my polyequiped dogbones IOT install banski's and I'd do it again... A C4 rear with polys gets stupid stiff... Banski's rod end dog bones restored my ride quality and retained the slotcar like handling I gained by removing factory rubber bushings. I did the entire polygraphite install even the batwings, no squeek or squeals during the 4 years the polys wer on but I did not realise how bad the car's ride quality was until I installed banskis.... Now if he comes up with front end components....... Mike |

I replaced the batwing bushings because I was doing a D44 swap and it was out anyway. There is a difference, it is worth doing. I did it all at once though so I can't say whether or not it is worth doing the batwing bushings. May or may not have had a noticeable difference without doing the batwing bushings.

With poly bushings and spring removed I could not move the rear knuckle by hand. With banski, it articulates freely. I have no idea how I got the batwing ones out, must've been when I had the rear end apart to upgrade to 3.45s.

Well I figure the binding will contribute to the net spring rate artificially with poor distribution, so going Banski will reduce effective spring rate and alter fore aft spring rate balance and henceforth creating lean and more understeer? |

Man card returned.
I did all mine at once, and went to solid delrin bushings on the batwing. The only difference I noticed was the car creaks more when I go over speed bumps. I noticed no difference in handling or street manners. |

I actually have a prototype front suspension on my car now. I've been to the track with it for 3 days and so far so good. I was floored by the difference made by replacing the poly bushings with the low friction ones I've prototyped. Just like in the rear, with the poly bushings in place and no spring or shock on I still struggled to move the suspension up or down. You could just see the poly bushing's shoulders mashed into the frame and causing binding. With these bushings in the stock control arms they go to full droop just under their own weight. I've incorporated a few changes in the upper control arm in an effort to ease re-assembly. I also made a change to the mounting of the lower control arms to try to reduce any excess clearance without making binding of its own. Unfortunately I've been battling other stupid issues that have kept me off track much more than I'd like but hope to get back to it soon. |

Delrin and aluminum. This one is designed to be used with the factory control arms so it's just bushings. I'm toying with the idea of the turnbuckle style adjustable length control arms as well. |

In theory no, let's face it, it's hard to revolutionize a simple shoulder bushing, and I've already admitted that it will be a delrin & aluminum bushing. I did the execution of the lower a little different in an effort to improve the rotation of the lower control arm by changing the mounting hardware as well as the bushings. When I had the new upper control arm bushings made I had a new control arm spindle made as well. I was able to install the bushings and re-assemble the control arms spindle with a simple bench vise. I did not need a press for re-assembly (I did need one to remove the original spindle and urethane bushings however). This re-assembly was something I was really excited about because once you've done that swap you're done with the need for a press to change bushings, liners or even the spindle itself. I could be over estimating the appeal of this feature but time will tell. I also am not doing the grease fitting on my bushings at this time. I'm just not sure why it's necessary. My goal has been to remove grease and grease fittings from the suspension wherever possible. I've succeeded in the rear suspsension so far and would love to do the same with the front. Teflon, Delrin and other polymer wear materials have great properties, even when dry, why not take advantage of that and not use a grease that attracts and holds dirt, grime and breaks down with heat? I hate greasing points on the chassis because I always seem to end up wearing more than I've put in. That might just be me  |

make sense, i bought an old shifter cable t complete my trans swap, the rubber boot was tattered, was opened to the elements, I stripped it off and exposed the cable, not unlike B and M who uses no boots, I figure the open boot will trap, hold water debris, and grit to accelerate wear, I wiped it dry so no lube can attract what I don't want and that's sandpaper, it'll be 100k miles before i need and new cable, so I get the theory.
price point matters on your items. |

Funny you mention not having to grease, I'm considering getting some of those rubber boots for some of the rod ends in back and filling them with grease to stop the squeaks from coming back.

Understood. Which is why I'm wondering if what I percieve as an improvement in including a new UCA spindle will be worth the additional cost to customers? I may end up making two versions: one for use with the stock control arms and spindle and another that includes a new spindle rod for those who wish to make that mod. I can't the see that advantage to grease in either however. |

I'd be curious to hear your results as well. One of the knocks on the rod end suspensions was the noise. I feel the Teflon lined rod ends help substantially in that respect. You're referring to squeaks which I think comes from a different source in the Teflon lined rod ends. I'd be interested to hear what you find if you did boot & grease the Teflon lined rod ends. |

The only other thing I can think of is the rod ends tend to twist in opposite directions over time, and the rod end could possibly be rubbing against the spacer.
I honestly think it's the chrome ball though. It seems to wear off and then build up surface corrosion. Not impressed with the teflon liner so far, but I'll check into it closer when I have a chance. |

When you installed them you need to make sure the rodends are square to the bolt going through them, otherwise you loose movement.
If the ends are at their limit when you tighten them down, you'll get rubbing. |

When I did my dog bones I was able to press the old sleeves out first. Then I took a wallboard saw and cut a chunk out of the bushings and it came out fairly easy.

On the trailing arms that shouldn't be an issue as the knuckle side is a cantilevered bolt so all the spacers and the rod end ball should butt up snugly. On the frame side I would think that a little torque on the 1/2" nut & bolt would make the frame bracket close enough to do the same thing. That would be easy enough to check, even without dis-assembly. Both ends of the camber rod mounting are pretty stout so you might not get that type of closure there. Quote:
And before that corrosion wears off you think it's causing the noise you're hearing? |

I'll check more later, I didn't feel like clouding your threads up with guesses. The original ones were metal on metal, no lining. I replaced those but the new ones finally started screaming. I have been swamped with other car issues, so I've just been shooting the noisy spots with silicone spray in the meantime.
