    I have a 2007 toyota tacoma crew cab, its a prerunner with the offroad package so I have a rear diff locker. Its not a 4x4 however I was told if I get bigger tires and rims it will effect the rear locker or break it? Is that true?

    Well I'd cross that dealer off your list.

    Unless you are planning to go up to something crazy like 37's, I wouldn't worry about any wear and tear on your diff or axles, and certainly not your locker.

    Any increase in tire size will put added stress to your diff. But unless your being really hard on it and abusing it, it should be fine. It's not the locker that fails. It's the gears.

    When the ground under your BOTH rear tires is the same, like on pavement... and you are driving straight... torque is going to BOTH rear tires (as if it was locked).

    The locker insures that torque keeps going to both rear tires when the ground under one is loose or missing... a condition that would otherwise stop forward movement since torque will rotate the loose tire and not move the grounded tire.

    So, if the differential can handle the larger tires you want to install, the locker changes nothing to that.

    .. ^^^ ... What he said ... I have a 4x2 OR (with rear locker) and it is important to keep BOTH rear tires the same size and you are OK.
