Can I replace my 2000 f150 4x4 rear end with a 2000 expedition rear end?

 

Long as its the same (9.75 or 8.8) it'll work. 5.4L had the 9.75 and 4.6/4.2 had the 8.8. What do you need replacing on your rear end that you would just want to swap out the entire thing?

 

I Accidentally Switch On THE 4H Switch thinking it was the heater switch and the truck locked up on me on the freeway and stalled .the gears left a hole in the differential and the tranny Wil also need replacing.

 

I've only seen a hole blown through a rear differential once and that was on a 99 AWD Chevy Astro, not sure what had happened but we ended up replacing the whole thing with a used one from a salvage yard. My dad ended up paying just a bit over $200. I would recommend replacing the wheel bearings, fluids and the rear dif gasket. Make sure it also has the proper gear ratio as well. If your original gears were not damaged I would swap them over to the new/used dif.

If the brake lines look good on the replacement then no need replacing them. But better to be safe than sorry.

Main reason why I am suggesting replacing the wheel bearings now is so you know when they were done. They can go out at any random time. Mine went out after 230K miles and never expected it to happen. I've heard them going at 150K and heard them never going out even with over 300K. 75w140 I believe is the recommended gear lube for the rear dif, full synthetic.

Hope this helps.

 

Ok thanks for the info..the guy I'm buying from on his expedition said he can only find something that says 3.31. I told him mine has a tag that says S829D. So i. Not certain if that's compatible

 

The housing wont work. The Expedition uses a completely different suspension setup than a F150.

 

This, the Expedition uses coil springs (or an air ride setup depending on model), so while it could work, it would involve a bit of fab work.

 

It locked up when switching to 4H? That sounds more like you switched it to 4L at highway speeds. It's made to switch to 4H on the fly (up to 55mph) so I would be very surprised that a few more miles per hour would result in a full on grenade in the trans/rear end.

 

I believe I'd look for a F150 rear end, you may be getting a "good deal" from the guy with the Expy, but after fab work and modifications, you'll probably be money ahead going to junk yard and getting one from a like model F150.

 

I decided to buy a rear end from a f150 from the wrecking yard..and a transmission cause I'm sure mines is shot.

 

Will a 02 f150 (4.6) crew cab 4x4 rear disc axle work on a 99 f150 5.4 4x4

 

If they are the same axle, yes.
These trucks had either a Ford 8.8 or Ford 9.75 axle. Also check if the replacement has the same type of brakes (drum or disk) to make the swap easier, as well as the same gear ratio (yes it can be changed, but easier if it is already the same as what is coming out).

With the 5.4 the 9.75 is the better axle (and I think 5.4 option gives you the 9.75 axle).

 

Yeah! Both axle the differential cover have 12 bolt whats the gear ratio

 

My 99 f150 have drum brake and i want to put disk brake on it

 

There's a hole in the differential
