I had my rear wheel off to fix a flat so as usual, I snooped around for,potential problems. Have you ever looked at the lateral links? They are for toe adjustment. There is a ball joint on the end. I'm used to seeing nice 'ripe' joint boots. Mine look dry and shriveled with no grease fittings. Not really sure there's a problem but it would be nice to be able to service them. Replacement parts come with zerks. They aren't real expensive but will change the aligmment.
