Rear diff fluid swap at 93k....might have an issue

Any advice or thoughts are appreciated

Check out the pics
I just performed 1st rear diff fluid swap
Found metal chunks on the magnet
Looks like a rivet to me
Fluid seemed pretty good for 93k miles & did not smell horrible surprisingly
5.5 qt out & 5.5 qt back in

Does any one know the exact torque specs for fill & drain bolts?
I set them to 40 both

Also the valve line flex fill fluid containers make it so easy & fast to refill the pumpkin....no more pumping the pumpkin for me...

 

I have a feeling my finding will urge many gen3 owners to perform a rear diff fluid swap to see if they find any metal chunks on the magnet....wondering wtf is coming apart in my diff????

 

Should be done at 30k, 60k and then 90k

It is likely pretty normal to see that much debris if it was first done at 93k.

 

In my manual it states to only check the fluid at 30,60, & 90k miles....it states to change if towing, which I dont

 

The good news is that nothing is failing in your diff. Those pieces are leftover debris from when the axle housing was machined. Although alarming to find, it’s not a big deal, and not all that rare on the first fluid change either.

 

Looks very normal for the initial drain and fill, those are shavings from the milling process.
I saw the same material in my '17 40k miles ago. Do a search, there are several threads on it.

 

Beat me to it.

 

Makes me glad I did my rear diff at 25k miles. 36ft/lbs on the fill and drain plugs.

 

Thanks for easing my concern
Much appreciated

 

Thanks partner!
Same as my tacomas before I turned into a tundra dude

 

No prob!
Enjoy the truck

 

how do these not float around the diff with that much fluid pressure at speed? i mean after i saw this video years ago it just baffles my mine how that doesnt float around.
