Well, be sure to check the bearing play as Ack said before you even take it to an alignment shop. They woudl likely check anyways, but if they didn't & your bearings are out of spec no alignment will help. The good news is your sammys bearings are lots easier to get to, repack, retorque, &/or replace than trackicks are (sammy has no crush bearing). Another thought: your 8" rims may be a bit wide for 235's depending on the actual tire width, which varies some by maker. 235's work out to approx 9.2" wide tread. Maybe the sidewalls are spread too far? 8" is actually pretty wide for a 30x9.50... maybe they're causing the tire to 'reverse' crown? Just a thought...
