Hey guys,
Next on the fail list: Rear Diff. Bearings are shot, weird because I actually serviced it so it isn't the factory fill. 2k left on CPO warranty so fingers crossed dealer fix.
Did you have any warning signs for it going out?

RDU bearings? Where are those located?

Still works but whine at 40 mph. Taking off the rear seat made it much more obvious.

Diff bearings usually tapered roller bearings on the pinion and gearset
Also adding rear sunshade gears ate each other another $100. I'm doing the retract when you put into reverse delete as even when its down it tries to retract causing the gear teeth to sheer off.
I'm getting a low hum at 40ish. I'm really hoping it's not the diff.
If it makes no difference turning left/right, it is worth checking the PTU/RDU fluids.

If you were asking me. No it's the same sound while turning. I was messing with that last night. I was trying to convince myself it was the tires. But it's not. I was hoping wheel bearing but with it staying the same turning I doubt it. Guess I'll have to crawl under there and check fluids. Both were changing around 13k ago.
Send samples off to Blackstone if you get a chance.
Take off the rear seat cushion and it should get much louder if it is the diff. Wheel bearings will change they way they grind if you do a turn at about 20 mph try both left turns and right turns.
If you look at my PTU thread, the gear shafts are tore up, crappy manufacturing. The gear shaft isn't hardned uniformly and the shaft got pitted.
Left and right make no difference. The weird part is no one can hear it but me lol. I did only start to notice after swapping my mounts. I'm going to pull the seat pad tonight on the ride home and see what I hear.
Fingers crossed its just the mounts and you're paranoid

For the first 200 miles with the new mounts I was on extreme edge. My car never made the sounds, vibrations, or direct driver inputs until I put the mounts in.
That being said, I love the DAMN things. The shifts are amazing, the driver inputs are magnified, and the sound! Inside the cabin the car actually sounds like it has an exhaust now. The pitch and feeling of the motor has completely changed for the better for me. Now other people may absolutely hate it, but not I.

I concur, I love them too! Could never live without now. Tim said he started hearing a sound after the mounts so I hope it's just associated with the mounts and not his PTU or Rear Dif. Another thing to try maybe would be to put the stock mounts back in and see if the noise goes away.

I actually laughed when how easy it was to swap them. Nothing ever goes that easy. Directly after installing them, I was rolling out from under the car..and was thinking EFFING Andrew and his peer pressure.
Lolol I'll be the guy saying "do it" then turn it on me..."I'm not doing that" I'll say! And thanks...of course I was under the car for longer than I'd admit...of course with ADHD anything shiny grabs my attention so I'm not sure how focused I was while looking over everything else I could see....i wasnt laughing though...I was like...how am I supposed to?
You 2 clowns kill me lol. I'm off tomorrow so I'm gonna swap the mounts back for the hell of it. Also I put 2 rear tires on since the noise started. I'm gonna swap them to the front. My dad road with me this morning told me I'm insane his mustang makes the same sound.

What you didn't like that accent GT?
Anyone have any idea how to know what the ratio is of the 100s of junkyard diffs available. Most of them just say SHO but don't specify 2.77 vs 3.16

Would you care to share how to do this? I don't have any issues with the shade ATM but use the function every day and I can only assume with a 10 year old, 100K mile car that issues might start showing their face sooner than later.
After a little research I found an answer, not sure this is the easiest way but it'll work. Removing the rear parcel shelf will give us access to the rear shade motor. Disconnect it and voila, no power to the shade. Here's a link to a page with the FSM diagrams to help in the removal for my MKS. I would assume SHO procedure would be similar. https://www.justanswer.com/ford-lincoln/8a7h0-lincoln-mks-2010-lincoln-mks-rear-sun-shade.html (https://www.justanswer.com/ford-lincoln/8a7h0-lincoln-mks-2010-lincoln-mks-rear-sun-shade.html)
For the SHO, there is a writeup on shoforum.com
https://shoforum.com/index.php?threads/2011-sho-clunk-sound-in-rear-deck-when-put-into-reverse.132930/#post-1455482
If anyone has access the ford system/vin lookup, would like to verify gear ratio for 1fahp2kt3bg128217. I think ZSHO would be my best bet.

Funny you mention that. I noted in my original post after installing these that it sounds like a Mustang with a quiet Magnaflow system inside the car, but outside audibly, nothing's changed!

You literally just nailed in words what I hear now. Wonder how much it will change when the DP's go on.

I've only had mine in with the downpipes. I can say outside the car is legit no difference with or without pipes. Cold start is the only noticeable difference. That and the slight turbo whine when accelerating.

Sorry for the late reply! Based on the VIN number provided the ratio is a 2.77 AFAIK! Z
Thanks Z your a savior!! Got another diff with 90k for $118

Wow that's it for a used diff? Argh maybe I will crawl under this thing and fix it.
There are 1000s of diffs because the "carrier" is the same across explorers, Lincoln's, etc etc just the gear set is different. It's was more difficult to find 2.77 ratio. PP sho is quite a bit easier 3.16 ratio. It wasn't worth touching the old 1 as I suspect the gears are fine but new bearings would quickly surpass $100 and tack on labor so triple $ of another uses diff.
I hope everything worked out well with that RDU! Z
