ok. i set up my gears last night. 10 bolt front. got perfect backlash on 2nd try. i don't have much money in this axle. it's all used parts. i bought new axle and pinion seals. using all existing berings. i haven't bought a crush sleve. i was thinking about just putting it together with an old one. hmmmm. is it possible to get decent preload on the pinoion berings without a new crush sleve??? the damned thing is $30. and with all the money i have in these damned expensive National brand axle seals, i'd be better off returning all that shieat, and buying the freking install kit from NAPA or Orlieys for $100. - and that would come with new berings and everything. i really didn't want to spend much on this wreched axle. so, i know everyone says, you need a new crush sleve and all, but would it be possible to use an old one? it is a FRONT axle, so it's not being used all the time. i just don't want to destory my pinion berings, and gears. keep in mind, i only have about $50 invested in axle seals, pinion seal, gasket, etc.
