2nd day. Custom has once again worked ALL DAY (Fueled by Maxwell House) relentlessly on the diff with nothing but great things to say about production!
The pics I have are with minimal lighting and not very helpful. But I will try to post some video this evening.
Still looking for a bushing encapsulated with upgraded urethane... Does anyone have one to offer?? If not, please send me someone highly recommended so I can purchase one. BMR??
Also if anyone has some information on diff lubricant: Normal operating temperature, and peak temperature. This will help in effectively testing the steel unit in my car.
Next will be a request for a suggested oil cooler to use with it, we have of course incorporated tapped locations for fittings. |

Here's a good pic. For those of you that have broken the cheesy loop that holds the pinion support bushing (like me), here's one with GIRTH!  |

I've got a Kleenex ready for when the price gets posted. Several possible uses depending on the number.

Heres the fluid needs:
Three quarts of #12378261 GM Synthetic Axle Lube SAE 75W-90
One 4 oz. bottle of #1052358 Limited Slip Axle Lubricant Additive (thanks to Reed @ Cadillacfaq.com for the info)
The normal op temp that I recall was in the 195-210 range...that stuff was always hot coming out during post 'new rear' breakin.
Hope that helps.

Differential, Rear.......... 2.7 pints (1.5 quarts)
I used Amsoil Severe Gear 75W-90 Synthetic EP Lubricant: https://www.amsoil.com/storefront/svg.aspx
And the additive: https://www.amsoil.com/StoreFront/ada.aspx
At 11K and diff is as quiet as a church mouse. |

Rob.....
Even though my signature shows a decent 1/4 mile run, I REALLY usual drive like a little ole' lady. I'm on my third (and it's noisy) diff. I don't do any clutch dumps or burn outs. How do you drive? I'm just curious, maybe you got a "good one." Thanks |

07 Diff and I drive it like I stole it.
But Seriously, I don't do clutch dumps but once she's hooked up I nail the throttle. Now I do get the occasional spin in 2nd and 3rd.
I do not baby it but I don't abuse it either.
Maybe luck, Maybe driving style, Maybe Because I change the fluid every 6K, Maybe it's because I use Amsoil...
Who really knows why it's held up but I am happy it has so far. |

Once again Custom has spent an entire day from sunrise to sunset! Here are 2 shots. One of the animated screenshot and the other shot is the actual diff to match. The RH rear mount ear is the block on top ready for machining.
Oh and for the record, in case you can't tell by my avatar or my videos in my public profile, I am very good at testing a vehicle's ability to handle abuse... I am looking forward to stress testing this diff. 
Thanks for the help on Fluid temps!
Still need pinion support bushing and cooler suggestions!
