Thank you for this video, my 2000 f150 with the 9.75 just blew today, still drives but it jerks when acceleration until I hit 30 and it’s thumping like crazy, least in assuming it blew, kid said he welded the diff for whatever reason and the weld broke
Thanks for the video. How different is the front differential from the rear. I have an 04 expedition that I suspect the front pinion bearing is going bad on. It makes a whining noise. I was told a while ago that one of the axel seals was leaking so I suspect it’s been run dry.
Hey brother, great video! I'm working on an 04 F150 4x4 with a toasted rear end. The driveshaft was jumping & skipping while the rear differential clunked, so I pulled the rear cover to find metal chunks & blown-up spiders. I'm trying to figure out the best way to get this truck back on the road.
I would recommend a full differential rebuild. You may be able to save your carrier, if it’s not damaged. The thing is, if you have the funds to do so, I would install new bearings, seals,spiders & Ring & Pinion. Let us know if we can help In anyway. Thanks for the comment. Be sure to subscribe.
@@axleoffroad Yes I think a rebuild is the best way forward. It beats having to source an unknown entire rear-end assembly & swap it into the truck while hoping it's going to work the first time & be reliable. The truck's VIN should have all the differential specs I need to look for new parts & rebuild kits right? Thanks for showing all the steps involved. I haven't gone through an entire differential before.
@@eddiesheeran5791 The Vin number will provide some information needed. Best way to identify the axle size is by the code on the axle tube. You can also get the ratio by counting teeth on ring and dividing by pinion. We use @nitrogears to order most gear parts. Feel free to email us if you have any question axleoffroad@gmail.com
@@gregoryhoward6449 Hi Greg, yes I totally repaired this issue without a full diff rebuild. I took the carrier assembly out of the differential case, and replaced the clutches & spiders with upgraded parts from Yukon Gear & Axle (Summit Racing). The ring & pinion gears were fine and didn't need to be replaced. I didn't change any bearings or seals either. I repacked the new clutches as tightly as I could. There are videos about ideal clearances & tolerances for this diff, I just watched a few before doing the process myself. I used the .035" clutch spacers, and my two stacks of clutches measured .645" each in total thickness. The parts fit very tightly, but the performance is excellent and the truck's owner is very happy with the result. I thoroughly cleaned the debris & old oil out of the diff casing before resealing the case and filling it with Royal Purple. Ford released a TSB saying to use 75w-140 instead of 75w-90. This is not a terribly difficult job. Just work carefully and always check your work before moving on to the next step. You can definitely fix this yourself.
My rear end is whining on my 16 Explorer. The wheel bearings didn’t feel like they had any play in them so I’m pretty sure it’s inside the differential. We pulled the plug and it was low on oil and had a little bit of shavings on it. I started to order a kit and replace every bearing in the rear differential but someone told me it might be a waste, it could be the wheel bearing after all because the all wheel drive models are made tighter and you can’t feel that slack by pulling on the tire from the outside. Any thoughts?
Keep up with the informative videos!
Thanks, will do!

Thanks for the comment! Glad our video can help.
good info
Thanks for the feedback!

should be very similar provided it’s a straight axle
7:54 what is the thing at the very top of the differential case called?
Spare tire? Lol

Hey Eddie! Did you ever start that project, I’m having a similar issue as you I also have a 04 f150

First word out of your mouth, I was like this is in Louisiana.
It’s that obvious? 😂
I was here to say the same thing 🤣🤣🤣🤣

very good possibility. front or rear?
@@axleoffroad rear
If the spider gear housing is missing a chunk ....can it still be used our is there a balance issue....
Great question. If in doubt, change it out. It’s cheap insurance to spend the money on a new one.
Is this the same rear snd in the raptor ?
I am not sure
Pretty much. Raptor 9.75 has an E locker and longer axle tubes
MF'r= Instant like lol
At least you understand mechanics 😂
9.75
Yes sit
