I just got my rear rims widened to 11", running MT 345x35x18. I have been rubbing on the drivers side. Put 1/4" spacers on. Helped a little but still rub when roads are rough. Sooo what is the best way to shift the axle over to center it better ? It is about 3/4" towards the passengers side. Can I just loosen the u bolts on the springs and try to shift it over?
