I have a early 99 f-250 i thought i had a 10.5 rear end but i have read i have a 10.25? Either or im looking for a upgreaded yoke i keep busting my at pulls. Any one have a idea

Its a 10.5

I recently tore up my rear end in my f-350. The Housing tag says 10.5 on it but when I opened it up, the carrier and ring gear have 10.25 stamped on it.
Why do they do this? You would think in an f-350 they would have the bigger ring gear.

I was told I can put an actual 10.5 ring and pinion, as long as I use the 10.5 pinion bearings.

YEA thats about what i got and im with you i thought the 350 would have a bigger gear set. does yours have the yoke that uses a stap kit or the flat 4 bolt flange

the difference between the two is in the bearings

:whs:

10.25 parts with the correct inboard pinon bearing and race can go in the 10.5 housing. but the 10.5 parts can not go into the 10.25 housing.
