locker problem

[brandon]

i have an aussie locker in the rear of my truck and today on the way fourwheeling i was almost certain that i could hear the locker racheting while i was driving straight down the highway..and i apparently that is what i was hearing....i took my 35x12.50 bfgs off and ran a set of 38x14.50's my buddy had just to test out....ive never had this problem before i put the bigger tires on it....i havnt swapped the tires back yet but im hoping this is what might be causing it....any other idea's why it would possibly be doing this?

I would think that the only reason it would rachet is if the tire speeds are different. Maybe the air pressure or tread is different on the tires.

it was something with them b/c i put my 35''s back on and it works fine..
