are you good with tools? if so, it's not a hard job. what all is being rebuilt? i've done a couple of dana 35's and they're not that difficult, you just need to pay attention to what you're doing. although one d35 i rebuilt was from my wife's wj and you could only order the axle bearings from a dodge/jeep dealer. and they were expensive. i think that one cost me around $300 just for parts. my d35 out of my 98 wrangler only cost me $100 in parts.
Can anyone tell me how the flux capacitor is used to facilitate time travel???
