ok i trying to find out what my rear axle in my truck is... I've got a 96' Ford F-250 with a 351, 4X4 E40D tranny, my axle code is 35. All I can find is its a 4.10 ratio open diff and it made by ford. But is it a 10.25 or ???, i would like to have some one put a locker in it but i wanna see what available for my rear end and i need to know what it is... thanks

 

I believe the axle code on my 95 250HD is 35 as well, and it has a 10.25 Sterling full floater with 4.10 gears, and unfortunately an open dif. Hope this helps.

AXLE code 35: 1990/97 F250/350 / Sterling 10.25 / 4.10-1 / non Limited Slip.

Ford confusion: AXLE code 35 was also used for 1990/92 Econolines w/a Dana rear axle (4.09-1).

1959 thru today: If the AXLE code begins with a letter: Limited Slip / If with a number, no Limited Slip.

 

sweet, thanks guys... that what i need to know!

 

I have a 94 f-250 4wd trubo diesel and would need to know which rear it has.I think it is the Ford 10.25 but I haven't had any thing but f-150's.I got the tag off of it and it is a 4.10 locker.I need to order pinion bearings so I need to ID it.

 

2020,
Your axle should be the sterling 10.25, if you what to confirm this, find the axle code on the tag on the insided of the drivers door frame.

OK, so the sterling 10.25 is the Ford 10.25 right?I'm planning to tear it down this week and hopefully just have to order pinion bearings.I don't hear any whine or growl from the gear set but the pinion is really loose so I don't know what to expect when the cover comes off.

 

Yes, the Sterling and Ford 10.25 are one and the same. I had an 87 that I had a buddy go in and replace all the bearings in it. So far knock on wood, the rear end on my 95 seems pretty tight, but I do need to change fluids though. Good Luck with yours.

Sorry to bring up an older thread but this weekend I'm going to look at a possible parts truck to buy and would like to know the what the code would be on the door tag for all gear ratio variations. It is a 1990 2wd f350 460 with 5 speed. My guess would be that it is a 4.10 sterling and from info above it should say 35 on door tag correct? If it is 3.54 or 3.73 what will it be? Info is always appreciated

 

We have only driven the old truck 4 or 5 miles but she seems to be OK.It does have a little whine between 30 and 40 mph,mostly on the coast side but the pattern looked real clean when I checked it on reassembly.I have had 2 other used gears that I got some noise out of after setup and the others were visibly worn.The noise isn't bad just noticable I guess.It had pinion bearings REAL loose when we got it so I'm thinking the gear could be worn some.

 

Im new to this what does the 10.25 full floater mean?

 

Welcome to FTE.

10.25 = ring gear diameter in inches.

"Full floater" means the axle does not bear weight. It only transmits rotational force.

A full floating axle supports the weight with the axle housing. The wheel bolts to a hub.

A non-floating, or semi-floating have the wheels bolt to the axle, and the axle shaft transmists rotational force and bears the weight of the vehicle.

A full floater:

Not a floater, note how the axle has a flange and studs to mount the wheel:

Thanks man preciate it

 

so is this heavy duty or just normal? what can i tow with this
and what comes in a 95 350 7.3 is it the same

 

It would be "normal" for that size truck, which is still considered a "light duty" truck. What you can tow depends on what else is going on with the rest of the truck. Auto or manual, SRW/DRW, ratio, springs, other equipment, brakes, tires....

It appears the 10.25" was used in that year F350.

If there is a tag on the axle, post all the info from the tag, and more can be figured from there.
