| Post subject: | Offset Bushings Questions |
I just got two regular bushings and two offset bushings. What are the washer things that come with the offset bushings for? And why are the offset bushings shorter? Moog K7103 offsets and 5601007 standards. |

Are these things supposed to be pressed onto the ends of the Moog offset bushings? There are metal caps on the ends of the regular bushings, but not on the offset bushings. One of the loose caps(?) is the size of the larger end of the standard bushing, while the other cap is larger. I don't see any mention of them in Condron's book. If anyone knows, which one goes towards the outside?

This is the first time I have seen the offset bushing and the standard bushing side by side, in real life. What is the deal? Why are there no instructions on (or mention of) installing these end pieces on the offset bushing? I have concluded that these things are end pieces, in part because the i.d. of the offest bushings is larger than the i.d. of the standard bushings. |

I am just doing this swap on my 69 Dart. The washers supplied with the moog kit will get pressed on after the Bushing is pressed into the Arm. Here are some shots: Old Bushing with STD size washer:   And NEw Moogs: Before Washer install:  After Washer Install:

Greg, What are you trying to do with the bushings installed so that the control arm is effectively longer? |

I was just following the instruction sheet. Is this incorrect? Greg |

When I purchased Moog off-set bushings they came with a thrust washer that slid into the bolt hole. Below are photos of thrust washer installed, and removed. I got two boxes or two pair of bushings for a total of four to do both sides of the car.   The larger washer may take the place of the thrust washer and ride between the adjusting ears. The smaller washers I don’t know, perhaps they are to fit under tightening nut that clamps the adjusting cams. |

Following the instruction sheet with two offset bushings will make the camber more positive and not improve caster. Most people want more caster and to do that you install one offset bushing in the rear of the control arm so that it shortens the distance between the bushing and ball joint. This gives more caster while maintaining a decent range of adjustment for camber. Where negative camber is a higher priority you can install two offset bushings toward the ball joint to effectively shorten the control arm. |

Ruh-rouh.....Maybe I need to redo this job again. Greg |

Greg, Are you wanting more caster? Negative camber? Both? |

surfing the internet and came across this text: "If you put the offset bushing in the FRONT arm, the arrow must point to the ball joint. If you put the offset bushing in the REAR arm, the arrow must point away from the ball joint to increase the positive caster numbers. Disregard the instructions that came with the box of offset bushings. The last photo shows the bushings installed. I installed offset bushings in both the front and rear arms of the upper control arm, although I found that was not necessary, an offset bushing in the rear arm would have given enough caster adjustment." make sense? http://www.gmcmidwestclassics.org/Web%20pages/align.htm |

Quote: Greg,
I was wanting to obtain more Positive caster.Are you wanting more caster? Negative camber? Both? When I had this car aligned before The shop could not get enough positive caster in it. So I am installing these bushings with the intent to improve positive caster. How should I go about install the bushings to do this? I still have the old stock bushing to use in the front if needed. Thanks, Greg |

The upper ball joint needs to move rearward to gain positive caster. You should be able to get what you need with one offset bushing installed in the rear of each control arm with the offset toward the ball joint. This will shorten the distance between the bushing and ball joint moving the ball joint rearward. |

Thanks Josh! Much appreciated Greg |

Got this project done correctly this time. Usually when I am replacing bushings I have no intentions of keeping the old bushings so I have not had a UCA bushing remover tool. I do have a shop press so putting them in has never been a problem  Here are some pics of a remover that I made using all recycled mopar parts except for a 3" length of pipe. -3" length of pipe ( not Mopar) -old spool mount motor mount bolt. -old tie rod end bolt retapped to 1/2-13 thread. - old shock washer drilled out to 1/2" - Seat belt Reinforcement plate (removed from race car) Drilled out to 1/2"      Also a Pic of the New A arm with the bushing(s) installed the correct way.
