I am replacing my 10 bolt w/ a 14 bolt s.f. /forums/images/graemlins/cool.gifThe thing has a gov loc in it /forums/images/graemlins/whistling.gif and I was wondering what is the main factor that causes the gov locs to break. Is it high rpms when it engages, lack of proper lubrication, to big of tires, or all of the above. Its going in my mall rated d.d. w/ 35" a.t. tires and 4.10's behind a 300 hp 350 that will see occasional mud and trail use but no extream crawling.
