I just changed my upper control arms. Pretty easy job . Just had a question about the alignment. Is there a different set up for the Harley trucks compared to the non-hd version? I put the stock bolts and alignment plates back in and it drove fine but wanted to check the final alignment. Well the set up was out of spec. So I ordered the adjustment bolt kit and installed and went back for the realignment. It's now with in spec but the stearing wheel vibrates from 30-80up. Any ideas?..
