A little back ground..I daily drive a 94 k2500 ext cab short bed truck. Its the lighter 3/4 ton so its still 6 lug. In the past few months I have put a new crate motor in, a rebuilt tranny, and now the rearend has blown up. I killed the pinion and everyone of the ring gear teeth and chipped. Im torn between what I should do to fix it. Its a daily driver, 60+ miles a day, and my tow rig for the beater. Currently has a 14bsf with 4:10s and a gov loc. 1. New Eaton limited slip, new 4:10 gears, master rebuild kit, new axle bearings and seals. $1000 2. Used gov lock, new gears, master rebuild kit, new axle bearings. $700 3. Used gov lock, used gears, master rebuild kit, new axle berings. $500 4. Drop in the 14bff that I have sitting at my parents, already should have 4:10s, its open, would need to move purches, shock mounts, its 8 lug, my wheels are 6 lug. So i would either need to convert it to 6 lug or buy new wheels and then change the front to match. 5. Trade the 14bff for a 14bsf with a gov loc and 4:10 gears, but the mileage is either 120k or 220k, and it wouldnt bolt in since its from an 88 suburban and is also 8 lug. Could swap the gears and gov loc to my housing. Cost of master rebuild kit and axle bearings. $250.
