Installing a aftermarket differential

1997 Ford F-250

I am wanting to install a after market differential in my truck and wanting to know ho hard it is to do. I have never done any differential work before besides for changing the fluid. Probably going to buy a LSD type. Another question, would it be cheaper to just replace the clutches? I know they wear out, but how hard is it to change them. I barely drive the truck. Just looking to improve rear wheel traction for pulling the boat out of the water.

I can't answer on the clutches but changing the carrier is a bunch of work and requires special tools. You will have to setup the gears which requires pulling everything apart and putting it back together many times while you add/remove shims then paint the gears and check the pattern. You will need a special $300+ clam shell bearing puller and a press to put them back on. Here's a writeup that will give you a general idea of what's involved.

if you're not going to be swapping lots of carriers/gears it is probably worth paying a professional. especially considering how important gears are

97 F350 Crew Cab LB 4x4 5 speed 3.55 320000 plus miles (parts truck)

a limited slip differential is a waste of time and money IMO
I put a Grizzly in my 10.25 just after Xmas this year, outside in my driveway.

you do not need the clamshell puller on the 10.25 as the shims go outside the carrier bearings.
you do need the master install kit from Yukon as the factory style backlash 'shims' are one piece non adjustable items.

I was working alone so no pics of the sterling but one pic of my 'workbench' doing the front d60 detroit install (where the clamshell makes it easier as shims are on the carrier under the bearings ) t can be done at home
