Taco is getting his rear spring tsb done on monday. The dealership thought my truck was a stock double cable b/c it was debadged, and tried to inform me it was only necessary for the 4x4/Prerunners. After "convincing" them that I know my own truck, they ordered the parts and we're going to get it done!
Anyone else in Tallahassee, FL. Legacy Toyota does the rear spring TSB with no fuss.
Now I just need to secure a loaner vehicle from them so I can still work!
