David I had a first rate machine shop do the work so I suspect the machinist knew how to deal with the issue you raise. Actually, the driver's side does take a bushing, it is to the right of the pinion (when viewed in the correct orientation from the driver's seat). A new bushing was put in and honed to fit to teh left of the pinion (making three total). Thanks for the caution, however, after adjusting the pinion bearing loading (for axial play - or lack thereof) and shimming the rack for what I think is the requisite tightness, there is no play in any dimension and the rack can be turned at the pinion by hand. I think I am ok, but time will tell. Philip |

Philip: Yeah, that's what I ended up doing a few years back as well. Two things worth noting: 1) The original bushing (nylon / sheet metal) is articulated, so you need to make the outside of your brass bushing barrel-shaped so that it can pivot slightly. 2) The driver's side does not utilize a bushing. If you installed one, you may find that the rack's movement will be too stiff --- the steering wheel may not want to return automatically after completing a corner. Good luck. |

Jim, David Charlie Edwards at the Auto Doctor in Evanston IL, has a friend in Indianapolis with a machine shop. It is a simple matter to pull the rack apart and then pull the passenger side bearing (1/4 inch nylon or plastic). I had them inset a 1 1/2 inch brass bushing to the passenger side and a smaller one on the driver's side and then hone to a perfect fit. $300, probably underpriced (it was closer to six hours work I think). Fabulous job. Fixed for the life of the car. On the adjustment, I was mistakenly reading the adjustment for the pinion. The rack adjustment is to shim the cover until there's some resistance when rotating the pinion 180 degrees in each direction by hand. Kevin (machinist) also made up a variety of new shims for me.

Yeah, Philip, we need info: names, prices, phone numbers. Inquiring minds want to know |

Philip Where did you get the new bushings? |

Gerrit I have a hard copy I bought some time ago and have also checked Steve's copies before. The issue is the legibility of figure 1 on page e-2. I think I understand it, but would like to read the chart to amke sure and just can't read the labeling. Philip |

I have had new bushings put in my rack. Old one (passenger side) was shot. I need to set the preload and, as best I can tell from the (faded) manual, believe it is done by a set of shims under the cover adjacent to the pinion with an 11kg weight and a feeler guage. Anyone done this? Advice? Philip |
