.............Not hard if ur mechanically inclined..u should have the shop manual for it ..u need a torque wrench, and all the bolt specs....u need a dial indicator with magnetic base to check ur back lash before and after u do the swap......u need the adjuster tool that slides down the axle tube to loosen/tighted the adjusters. i think a torsion bar will work, but not positive....u will need new gear oil and a friction modifier[additive]..1st thing though is to make sure the sure grip unit will work with ur gears, as i believe 2.45s have there own...i haven't did a 8.25 for awhile but i think the crown gear bolts are left hand thread...kim.......
