Front UCA and urethane bushing install questions (Page 1/1) frockfiero NOV 09, 07:46 PM In the Fiero service manual, it states I need to have 2 spacers totaling 12MM to resemble the front upper control arm, however with the amount of overhang from the new poly urethane bushing, end caps plus the 6mm washer there is simply not enough space. The measurement of the poly bushing from the control arm lip is 4mm on each side (8MM total) do I need to add 1x 2mm washer to each side totaling 12mm, or is there something I'm not doing correctly to put two 6mm washers on each side. 1987 Fiero GT frockfiero NOV 09, 10:34 PM Found this on the forum and solved my issue. I wanted to post it here encase someone else had a similar issue. Basically, I had to back the busing out flush with the UCA and then install the spacers. Once installed I tighten the bolt to push the bushing back in, then loosen and torqued it to spec. https://www.fiero.nl/forum/Forum2/HTML/094633.html
