have a question I jus put new tires on my truck 3 months ago since then I been aligning almost every week taking it back because I leave from the shop and it runs perfect once I get on the road after about a day or so it starts to pull to the right again like it gets out of alignment been having constant problem I have replaced shocks, leaf springs , wheel bearings , and still the same they say supposively the tie rod ends are good but thinking of replacing that to see if it eliminates the problem it's a 2005 freightliner Colombia any one have had this issue to know why it gets out of alignment
