2006 chevy trailblazer_lt
I cant seem to find out via old threads if an 2006 standard differential has a drain plug or if I would have to pop the diff. cover off to change the fluid. Also I checked my RPO codes and I dont see G80 on there, so I know my rear doesnt have a locker, but someone said the fronts are all lockers? just curious because if so I hope the amsoil gear oil I bought can still be used on both when I change them next weekend. Thanks to anyone who can advise me better on this.
