they're not bad if they are taken care of, not abused..i had 31's and did mudding, rock climbing with mine, now i have 33's , most say thats the max size for a dana 35, i'm still searching for a d44 or a ford 8.8 with 4.10s to match my front diff gears..

best to open the diff cover and check the gears, take a pic and post it if your unsure, look close at the center gears/spider gears..they are the weak link and when they go they take the ring and pinion gears too..

hmm, i'm sure theres lots of info on the gearing out there...

say a gearing of 4.10 to a 3.73 or 354

the 4.10 the driveshaft rates 4.1 revs to 1 on the axle allows more torque to the axle but hurts the top speed of the truck and fuel economy.good for towing

a 3.73 or 3.54 would be better for top speed and economy. but the 3.54 would be less of a towing or light load towing..

hope that helped..and this

There's a tag on the diff with some numbers on it. Clean it up and post those numbers.
