Bob-When you say that you replaced the bushes, am I correct in assuming that you put your originals back, just after rotating the upper and lower bush the same degree in the same direction to take out the slack?
I saw no evidence of any wear on either of my rack or pinion gear teeth, but do see some evidence of moderate wear between the rack and ID of the cast and machined aluminum rack housing. Perhaps you might be the one to settle the debate by getting you rack housing ends bushed to see if that cleans up the other third of your play.
Don't forget to make a simple brace to stabilize the end of the steering rack to a nearby floor bolt if you want to eliminate the counter torquing of the rack at full lock when your road wheels are not rotating much. I'll send you a picture that I just went out and took so that you will both know what I mean, and can put it on this forum if you think it worthwhile. Mine is obviously over built. I am sure you could make a better one quite simply, and I don't have time for the photobucket complexities to complete the posting at this time.
While I've got your attention- do you know where i could get door aperture weather stripping and a front shock absorber for my Nobels? It is obvious that I am not going to be able to afford a new ignition switch.
