You should have a sterling 10.5 and a Dana 60 up front...

As mentioned before Randy's ring and pinion is a great place to buy gears, highly recommended...

Go with Yukon from Randy's Ring and Pinion. You'll have a D60 front and 10.5 rear, you'll use 10.25 aftermarket gears and for install kits get the D60 master install and 10.25 master install. I'd go with 4.88s, but you could get away with 4.56 if you never tow and aren't too hard on your tranny. Also, the D60 has a carrier split at 4.10 (different carrier offset). So you may need to get a new carrier if they don't make 4.56 or 4.88s for the 4.10 and down carrier. If you do need a new carrier, do yourself a favor and put an E-Locker in the front

Where in Washington are you? Randy's Ring and Pinion is up near Seattle I believe, you could just have them do the job, they would be the best.

After you buy the gears you will need someone with a press and elaphant ears to remove the bearing off the old pion and get the shim that is used. plase that on your new pion then press your your new bearing on. You will have to cut a small slit in your old pion baering and use that to press your new one on. When you take your old gears out make sure you keep the left shims on the left side and the right shims on the right. Take a micometer and meassure each shim and then add them up Don't cluster them togeather and take a messurment it will give you a wrong reading. Do that to each side of the carrier and will give you a good starting point to meassure your run out. A good trick for putting the carrier in with the shims is to put the carrier and shims in togeather at the same time instead of putting the carrier in then the left side shims and then it binds up the right shims. Also when butting the bearings in make sure you pour some gear oil in the bearings to get yourself a accurete reading on your prelode.

Tools needed:
Mircomater
runn out gauge
press
torque wrench
impact gun the get the pion shim down
also you will need a prelode torque wrench.

Don't just blindly use the same pinion shim though. Most pinions are marked with their variance from standard (+2, -2, etc, in thousands of an inch). Also, bearings can vary, you'll need to check the pattern after its assembled and from that you may need to go back in and change the pinion shim. Don't assemble it with the crush sleeve and seal until you know your pattern is correct.

I porbly due 10 or 12 rear-ends a week especially when the ford lightning came out with the recall on all there rear ends, and I can count on one hand how many pion shims I have had to change out other then what was used stock and make sure you get more then one crush sleave. You will probly crush it to tight the first time after it gets snug to a trigger pull at a time and then messure your prelode and then repeat.

My gear pattern was OKAY with the stock shim, but I wanted it to be perfect so I ended up making 3-4 fine adjustments.
