    Allright, I need to put some 4.11's in my front end. I've found I can get a used set for about $15. I know a guy that can put them in pretty cheap too. My question is, I've heard that once the wear pattern is already established, you shouldn't re-use the gears, or put them in a different axle...isn't it possible to shim by front end the same amount so that the new wear pattern is pretty close? I talked to friend who knows a little about this stuff, and he said that it would probably be fine. Its also going in the front, which I hardly use anyway...but I don't want to have to worry about it later. Any opinions?

    i have been told that. but i have also seen LOTS of 2nd hand gers being used with no problems. i would go for it at 15 dollars plus install. you do it right as long as the patern is right you should be fine

    for 15 bucks?

    hell, it's in the front end, just set it up for a good pattern and amaze people as it holds up ....

    a friend of mine had his front spiders stripped, taking out the tips of 2 ring gear teeth....

    i shoved a new tru-trac in there, "eyeballed" the shims, got a good pattern, filed the chipped parts of the teeth down, and called it good.... we beat the crap out of it last weekend with some highspeed wheel-wobbling pull-out blasts and scrabbling across grippy granite, and it did fine....

    greg ( 'eyeballin'.... nice, huh?)
