reason not to drill drain? - i'm seeing online that these need an occasional oil change - the one i just got is 10 years old with it's original oil (i assume) - just curious

that pull & pay parts yard contacted me that a 2014 edge had just arrived in their yard - went out there and pulled the differential out - took 2 hours - jspec i took your advice and removed the entire pass side knuckle - hard to do in a yard - they don't allow you to bring in a jack so you're unbolting things under spring pressure - but it is in my garage now it's an exact replacement for mine - most of the oil dumped at the yard but i set it on end in my drain pan and got out 6-7 ounces of oil - i don't see any metal in it so maybe i got lucky my plan is to get new seals and flush it out - i have some 75w-90 gear oil here to flush - or should i use something like kerosene to flush it? - the seals cost almost as much as this unit - pull & pay charges a flat price for parts no matter what kind of car they come from - so a differential for a ford is the same as one from a porsche - it was $128 out the door - hopefully get this in, in the next 30 days (that's the extent of their warranty) i am also planning on drilling a drain into it - anybody have a quick link to instructions for that? - that way i can make changing it's oil an every 10K mile or so job - thanks for all the advice - will check back when it's in - also going to open my bad one up and see what's what in there

cerberus don't beat yourself up too bad - sure you could have checked the fluid level occasionally ( i never checked mine either) - mine did have lots of fluid in there..just lots of metal also - of course Ford could have put a drain on it at almost no cost and then maybe? we would have looked at it sooner

i mis-typed - i meant 2013-2019 - that's what most of the ones i see online say will fit mine - now the actual S designation (mines an S-154D) changes to something like S-150A or S-164A or something similar, but they say they will work in mine - i have done a cursory search and it seems i can get a new one from ford for about $1800 - i see some on ebay with 100K miles and they are asking for $1500 - since i partially swapped out some of the gear oil in it, it has gotten quieter - so for now i'm going to change out all the oil and see if that further quiets it - i know it needs replacing and i'll keep looking for a replacement - hopefully it will stumble through winter and i'll find one in the mean time - car doesn't get driven much (5-6K a year) - and you are correct about me mixing up the RDU and PTU for the drain plug - although i don't see why ford would not put one in the RDU - thank you for your input on this

been looking locally - no later (than mine) ones available - i thought i read that ford did start putting a drain plug in these - if so..what year did that happen? - also i've been looking for one from 2011 - 2019 (athough really looking for one newer than my 2014) - all those years should fit the 14...correct?

yea..i've been shying away from a used one - simply because from what i'm reading these RDU's go out fairly regularly - i don't want to put a used one in and just have it go in a year - but..i guess if the chinese ones are crap and can't be coded, and a new ford one is a quarter of what the car is worth, i'll start looking at used ones - there are a couple of pull-and-pay scrap yards here in denver - i'll give them a look first - at those i can see what the mileage on the car is (maybe) - also they charge a flat rate for parts no matter what car it's from - thanks for all the input - will let you know what i find

still shopping for one of these RDU units - jspec...i found your ebay guy ...price is now about $1450 - but they are new ford units - all the others (far less $$) seem to be chinese ...which i'd get except, so far, none of them come with a coding number - i've asked and some of the sellers say it's not needed - one told me they can't send it with numbers because of customs...? - thoughts? - can you retrieve code numbers from the unit itself - maybe with my programming tool?

so no one on here has replaced their RDU? - if so what did you use and where did you get it? - i can't find a rebuilt S 154D anywhere - S 150A and S 164A (different gear ratios?) are widely available but it seems the ones i've found are not real Ford units (although they show pictures of actual Ford units) that have been rebuilt - they are chinese manufactured units and when i ask about the code to put in the car's computer they are vague in their answers as to whether the codes are good and if the final gear ratio is compatible with the s 154D - if i look up the RDU on Ford's parts site it cross-references to MU7Z4000J and says that replaces the S154D ...$1900 - so ..not sure where to go with this - are there any other forums for these cars that might have more members who have dealt with this?

sorry it took so long to get back here - this is my wife's car and i needed a day when she wouldn't need it - i siphoned out about a pint of oil - i guess i would need a thinner siphon hose to get to the bottom of the case - i had cleaned the fill plug magnet about 3 weeks ago - you can see that in that time it has completely filled up again with metal - also, a picture of a little bit of the oil in the drain pan - lots of specks in there (and that was just the drips as i actually drained the differential into an old oil bottle) - and finally a pic of the magnet sludge smeared out on a rag - no big pieces of metal but those could be down in the bottom of the case - so it seems i've found the culprit for the growling noise - going to get a rebuilt one and see how that goes - anyone recommend any sellers of those - some come from china - are those actual ford diffs that have been rebuilt or from some other manufacturer?

1004ron...i looked at the center shaft bearing - shook it - didn't feel any side to side play except for a little in the rubber - normal..? - jspec...i did not drain the differential - it seems there is no drain plug - i did add about 5-6 ounces - i could siphon it out and replace it - but to be honest this noise sounds like more than an oil change could fix - but i will give it a try - i don't have access to a lift so putting it up on jack stands and spinning all four wheels doesn't sound like something i want to try - i also disconnected the RDU electrical connection and drove it around the block - wrench light came on saying check AWD - noise was much less noticeable with RDU disconnected - reconnected it and noise was back to previous level - so are all symptoms and tests pointing to RDU? - in my mind it seems to be - thanks for your responses

i answered my own question - hooked my launch coder up and it does have a way to enter the barcode for the ATC - my existing code is shown and it asks if i want to change it - so now i'm only wondering if it is actually the RDU that's making this noise - since i changed both wheel bearings and half shafts it seems like it's the only thing left - unless there is a bearing on the main drive shaft from the front that is separate from the RDU - is there one?

hello everyone - brand new on this forum - i have a 2014 edge sel awd - never got on any forums for it because the car has been so dependable i never needed any advice - well now suddenly it's got a noise in the rear - sort of sounded like a bearing - will disappear for a second between gears - so i replaced the wheel bearings and shafts - seemed like the easiest, cheapest route - noise is still there - so it's the RDU...? - i can replace it but it needs that coding - i have a launch 919E - it has a code feature for ATC#1 on it - is that what i need? - anyone used the launch on these cars? - noise is gradually getting louder and i want to fix it before it becomes a major issue - right now it's just a noise - thanks in advance for any insight into this
