got some bad vibes from my driveshaft found it is the pinion or pinion bearing, originally thought i had 3.08 gears, fornd out they were 2.56. running a 350/350/208 and 35's this just wont work. so ordered up 4.56 gears and a tru-trac limited slip for the back. this is for a corporate 12 bolt rear. 10 bolt front will be next. but if you want to do your own gears this will give you a reference.
tools i used so far
verneer calipers
dial indicator
torque wrench(inch pounds)
1/2 drive ratchet misc. sockets
long breaker bar
pry bar
1st
remove axle from vehicle if possible, remove shocks, brakes, springs arms whatever, get it on your bench. before i removed mine i took the axles out first, these are c clip axles so you will need to remove carrier. if you do this mark carrier retainers so they can be put back on same sides.
2nd if you have not removed carrier check your backlash. backlash is the amount your ring will move back and forth with the pinion being held, i used a large adj. wrench, set dial indicator on magnetic base or attach to housing, indicater should be set up on the tooth of ring gear, move back and forth check in a few spots, my 12 bolt should have .006-.010 movement, mines bent so i couldnt do this.
3d with carrier out and pinion in place i set up a square across housing marking the points i put it, then used calipers to measure pinion depth, rotate pinion and check in a few spots(use average)
save these numbers you will need them for re-assembly.
4th with torque wrench check pinion gear pre-load, with inch pound wrench, see how much force it takes to spin pinion, you will need this if you dont have torque specs for your axle.write it down.
remove pinion, i used big adj, 18inch braeker bar and a 6 foot long piece of pipe, came off in 30 sec. use adj to hold yoke.
take out nut and washer, then i used a puller to remove yoke
after yoke is off tap with rubber mallot to reove pinion, carefull not to damage threads if you want to keep parts. when this comes out, crush sleave and bearing race will come also so be carefull.
this is where im at till thusday when gears get here. hope some people will find this helpfull. this is the first time i have ever done gears as well. just want to prove this can be done rite in your garage.
