Yet another failure

[polskifacet]

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? 

 

[shoNoff]

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.
