Dealer claims it was a bad replacement differential from the factory. They sent it back to ford to analyze.What was the issue for previous one imploading?
3rd wow, they didn’t replace my transfer case.I’m on my third front diff and transfer case. I’m doing the lemon law route if that helps. Ford customer service isn’t helpful, but you’re lucky you got the part quickly. First time mine had to be replaced was in the shop for 28 days. I’m currently on day 50 for the third front diff replacement with no ETA on part. Feel free to PM me if you want more info on my issues or you can search my threads, I’ve written about it in detail on the forum.
Well, I wheel mine all the time and not one issue!If this is happening on surface streets how can we feel confident wheeling?
great picturesWell, I wheel mine all the time and not one issue!
Sorry to hear about your issues, but it does seem to impact a good percentage of owners, I am sure many have leaks they just don’t know about yet. I believe Ford is mostly replacing them now, no rebuilds based on Ford service tech guidance on their inspection and report.My front differential blew apart back in November right at Thanksgiving . I believe it’s a venting issue . My Bronco is a 21 badlands sas 2.7 with 46,000 miles . Early last year had my oil changed and the oil change tech said oil leaking from wheel bearing area. So after oil changed took it to service ..they had a tech put it on lift and said all was good just some manufacturing leftover residue. Well fast forward driving down the road on thanksgiving day and Bronco shuttered and felt like power cut off got off the next off ramp (couple miles) and sounded like a metal bucket of bolts once at low speed. Ended up having it towed the next day. I waited 3 months for parts to rebuild the differential. Got it back this late February. Took it to get oil changed 3 days ago and oil change tech says oil all over differential area. Have appt Monday morning to have tech who rebuilt differential to look at it. I drive about 1 hour 10 min to work one way at about 70mph ea day, hence all the miles on Bronco. I believe the high speed generated over that much travel at higher speeds with the sas setup is causing too much pressure in the differential leading the seals to fail and oil to get flung out under high pressure and eventually catastrophic failure of the front diff From lack of oil. The fix might be as something as simple as a different spec differential vent valve@fordmotorcompany. Another reason I think this is that I work with 2 other peeps that have Broncos..other two are lifted aftermarket ..both running 35’s. One lives slightly closer than me to work, the other just a few min away. The ones has had zero leaks or problems that lives close, the other lives far and same issue ..needed new differential.
so you are saying the guidance is to replace not to repair the differential. Do you have access to a service bulletin that says that?Sorry to hear about your issues, but it does seem to impact a good percentage of owners, I am sure many have leaks they just don’t know about yet.

After my second replacement, I just had the right axle replaced due to CV boot, tires rotated, and alignment.
One thing I have noticed is when I am going really slow, like 2mph, and turning left or right I have my steering wheel shaking, not even on full lock turn. Honestly I don’t remember if this was like this before the issues. Tech says it’s normal because of the MT tires. I may just be hyper sensitive to symptoms now.
Either way I am going wheeling today at Cleghorn trail here in SoCal to get some proper mud on it and see how it goes.
There is no TSB, but there is an updated procedure techs have to follow to validate the issue and document it before they can order a new differential. As far as rebuilding the gearing in the differential, I was told they don’t do that anymore.so you are saying the guidance is to replace not to repair the differential. Do you have access to a service bulletin that says that?
Let me post the offical description of the modes and transfer case operation. This is a good read for everyone so you are not questioning whether you should or should not be driving in a particular mode.Socal roads. I only use 2H. Why run more gearing. More heat. Less gas mileage. Save your drive for when you need it. Cleghorn is great. Have fun and lots of sideways upthere. Correct me if im wrong, doesnt sport run in 4A keeping all your gears in motion. That transfer clutch is there to wear and create heat. If i need 4 wheels, i use 4H.
4A, electric parking brakes, electronic transfer case, all defeats true offroading. I love the independent front end though.
