I think I had this problem, before...I went with one rubber and poly bushing. Now though, I have the, I think it's called performance T/C rod bushings...it's that ball socket type bushing. Anyway, when I tried two bushing, I had someone pull on the hub assembly forward while I got a few thread on the nut, set the car back down on the alignment rack and torque down to specs, or you can set it on ramps. I had access to an alignment rack at the time. It is a dangerous move doing it this way, but it was a chance that I was taking. Just telling you how I dealt with the problem.
