change the carrier too, its one of the most common causes of 10 bolt ring gear failure.

yes, at minimum you will need a minor install kit to get the shims and such to get the pattern right.iwaxmyjimmy said:
that said, i would upgrade axles. i would put something bigger in it because you most likely are gonna have problems with the 10 bolt again.

better gears, bigger brakes, stronger axle... the downside, 6 lug wheels wont work anymore. there isnt a better bang for your buck for these trucks than a 3/4 ton swap.
i dont have the money or the time to do the 14bolt swap i just gotta get back up and running. i guess ill order the install kit sometime this week if my wallet allows. w/ a 4.88 gear i should be ok w/ light wheeling b/c that will take some strain off the axles and drivetrain b/c ill have more reduction to turn the 33s. correct??

$150 is a pretty common price for a 14FF, add in pair of 8 lug wheels, and maybe some brake parts if they need a little attention, and you're still in under your price for a r&p, install kit, and a different carrier. the problem still exists downstream of the gears, the carrier and axle shafts are where the problems really lie with the 10 bolt. 4.88s are going to make them worse due to more torque multiplication. say you're putting 300 ft/lb to a set of 3.08s... 300 x 3.08 = 924 ft/lb to the carrier and shafts... now factor in a set of 4.88s... 300 x 4.88 = 1464 ft/lb now put your transfer case in low, and the trans in something lower than direct drive, and the problem just gets worse. if you're breaking 10 bolts with 33s and stock gears, you need a strength upgrade. the 4.88s will definitely make the rest of your drivetrain (engine, tranny, and tcase) alot happier though.
When you start getting into that deep of a gear in the 10 bolt axle the pinion gear becomes so small that they start to grenade pretty easy.

simply put: the General used 10 bolts as a way to sell more ring and pinions to poor bastiges who didnt want to swap to a 14bff... it is in your best interest, physically for your truck and monetarily for your wallet, to forgo new gears and install a matched 3/4 ton axle set that can be had for 300 bucks and maybe another 150 in lube and brake parts....
i just ordered the r&p install kit from summit and im not plannin on wheeling for a while mainly b/c im only gonna have 2wd. and everything should be here tuesday and maybe ill have the gears in weds. this is my daily driver and i gotta work ya know and it might be a lil bit before i can spend the 500 plus to get a 14bolt FF rear and 3/4 ton front 8 lug wheels and some new tires b/c i dont think i can fit a 15 inch wheel over the calipers on the front.
this is a temp. fix ima swap 4.88s in the front too along w/ a mini spool up front and lockright rear in hopes of having a local club member buying them to go w/ full width, locked, and geared for his jeep or sammi or something. then ill buy my 14bolt rear and hi pinion 60 front w/ a Z71 manual T-case after i get the cash. ive just gotta keep my truck rollin till i get the cash for the swap

for a temporary fix, i'd just throw a junkyard rear in it, but if you're set on dumping money into axles that are just to be replaced, i guess there's no talking you out of it. as for the mini-spool/lockright idea, swap ends... spool in the rear, lockright in the front, dont and you wont be able to steer it.

yup, what it makes up for in ring gear size, it loses in pinion bearing size.
