Apologies for the newbie question - I'm really tired of searching...

Any difference between Excursion (2000) and F250 (99-00) rear axles?

Car-Part.com lists them as interchangeable, but I read something somewhere about different caliper mounts?

What's the answer?

What's the best way to search the forum when talking about truck parts? "F-series"? "F-250"? "Super-Duty"?

I want to put shorter gears in my 2000 V-10 2WD 3.73 Ex. It looks a whole lot cheaper to buy a 4.30 axle vs having gears installed at a shop.

I appreciate the help!

 

99-early 2000 f250 rear axle has caliper, one side front one side back
early 2000 excursion, same
2001+ f250 and excursion, both calipers are in the back


99-2000 f260-excursion front axles are both Dana 50
2001+ f250 front dana 60
2000-2005 excursion dana 50

a leaf sprung dana 60 will work in your excursion just fine, only requires you to shorten the dtive shaft 1”. and easy task for a drive line shop

 

Unless you find an F250 rear end that somebody swapped 4.30 gears into you will find that they came from the factory with 4.10

the axle code code you would want is c3 if it still have the tag from a 4wd ex

i have factory 4.30. Needle in the haystack

 

You find the vast majority of F250's had 3.73...at least the diesel F250's.

 

understood - thanks!

 

What is your ratio of commuting in your truck versus pulling?

I have 430 gears and tow about 8000 pounds with a cab Full of kids and dogs and junk. And find that I still have to run with overdrive off unless it’s on the flattest freeway with no headwind.

Stock size 265 tires. It had 245 on it when I bought it. I liked the shift points better.

Since I mainly tow with mine if I had 3.73 gears I would gear to 4.56

just a suggestion if you tow heavy a lot.

 

I think 4.30 will be more common in F-350 than 250. I assume the axles interchange the same, but don't know.

 

Not it that I have any problem with a 4.56 gear for a tow rig EX but you should be doing better with stock sized tires, 4.30 gears and an 8K TT. Do you use a tuner and custom tunes? I tow a 12K TT which puts us at 20K combined weight with 4.88 gears and 35" tire's for an effective 4.39 gear ratio and 5Star Tunings 89 Octane Performance tune and I always tow in OD where it stays on all but the bigger highway grades all over the East. The custom tunes bring a new trans shift strategy which really improves towing performance.

 

Thanks!

This is not a daily driver. I bought it to tow the toy hauler. I'll drive it roughly once a week to keep the battery charged and fluids moved, but I have better/cheaper options for commuting.

I'd like 4.56 gears, but quotes locally for $900 -$1200 for 1 axle (2WD) got me looking for other options.

 

i assume the 900 was without bearings snd $1200 was with new bearings ?

 

Do the shocks mount on the axle in the sample place for the excursion and pickup?

 

The $900 estimate included the master rebuild parts I assume include bearings.
I did not ask about the $1200 estimate because I needed no further information.

 

Go with shorter height tires? Maybe. If you can stand the look. That’s what I do on my tundra work truck. Loaded at near capacity gvwr all the time I like it better.

If your tires are new then not cost effective.

Run with od off and keep your 3.73 gears. Noisey but it works.

Cheapest axle swap is junk yard f250 w/4.10’s still takes some time to do. But an afternoon in the driveway and done.

Most of my towing 75% at least is hilly 2 lane roads. Not highway. You can’t climb hilly roads at 55mph in od.

Gears and tuners are nice but not necessarily budget friendly.

Try it for a while as is and see if you can live with it.

I have a 99’ build motor. Probably the lowest hp/torque v10 version. I don’t like mid hill hard downshifting so I drive like the manual trans I grew up with and anticipate the need for a lower gear.

I hauled with 3.73 gears in a f250 1986. Lots of horse trailers and hay. No od. Ran better with 245 tires. Noticeable.
