[younggun45]

I have a 97 F-250 HD and i am lookin at gettin a posi lock and i need to know the size of the rear end iv heard a dana 44 or dana 60 but im not sure help!

Hmmm same question here, mines and 03 f 250 7.3 fx xlt. Can anyone tell me what axles and gears I have?
Also i was thinking of putting a locker in just the front axle any opinions on this?

The 97 should be sterling 10.25 axle and the 03 should be sterling 10.50 and dana 50 front axle. As for what gears you have there should be a tag on the front or rear end under a cover bolt or axle code on the door, that is unless someone has changed the gearing. As for a locker in the front end it will make it steer a whole lot different especially with the amount of weight over the front axle on diesel trucks. dr8082 I take it you want the locker to run in the sand on the outer banks, just keep in mind that running in soft sand with a front locker will be hard on your locking hubs and if you still have the stock ones I wouldn't trust them to be up to the task.

An 03 will have a D60 front, the D50 went away around 01.

Your right I forgot about that.

1deiselman, the tag on my rear hogs head reads: 3v423c and L730152H12.
If I understand right the fx4 in the 03 is a limited slip. As to the locker in the front, would it still be hard on steering and hubs with the front hubs unlocked during road driving? I assume u mean while the front is in use while off road steering would be hard.

Thanks for your time.
