Several things I have learned is there is no great way with out the special tools with that being said I have done many sets at the ford house and at home with out them and have never had any problems out of any of them. Pinion depth is probably the most crucial measurement in setting gears. I made a plate that bolts to the cap holes and goes straight across the bottom. I bolt it down and measure from ther to the head of the pinion (wih carrier a@d caps removed). I then take that measure ment right it down. I do as johnny stated and measure from the head of the pinion to the back side of the shim and try to get a shim that gets you close to the same thickness. Install and check the depth against the above measurements. That way you check your work.

I also try to set back lash at 8-10 especially with new bearings as they will wear in a little bit. Also raetech sells a crush sleeve eliminator that makes this process very easy and its reusable for around 20 dollars

Well the 4.10 are installed and no noise from the gears. The math came out to a .032 shim on the pinion and the backlash set @ .009 ...thanks guys for the advise above...

would any of this be similar or useful to installing 3.73 gears on my 92 ?

Yes it all applies

[fbodyjohnny]

awesome, didnt know if it would be different with different gears. what all tools are needed? i just bought latemodels big 5 lug kit with 3.73's and a new trak-lock diff in 31 spline, so im tryin to figure out what tools i need so i can make it all a 1 day event when i get home from afghanistan

ford recommends 8 to 12 thousands 13 being 2 loose and 7 being too tight. are you getting 12 with the axles in? so i always go in the middle at 10 with the axles out then it comes to around 8.5 to 9 with the axles in

How do the axles make it change? Not following, but always ready to learn.

you shouldnt use the axles at all in figuring
