My son Logan and I visited friends and family in the D.C. area on Sunday. Left DC at 6.45 home by 11pm....The steering box adjustment Sweet did in the GMC.... ELIMINATED!! the bump steer issues I had been having and tightened any wheel play...the new speedometer cable that Jay(Magic Man) Lugnutz helped me install kept my speedometer needle solid as Gibralter.....no more jumping around like a flea in a frying pan......
