Day 38 at work and I'm starting to lose it
SO, since the work load has shifted to "hot stand-by", I checked my build log and decided it was time to order some of the less glamorous stuff needed to finish a few projects. First, I need to tackle the rear end. I'm going to drain the gear oil and 'start fresh' so that I know exactly what fluids I have. TO THE INTERNET!!!! After being confused by the Eaton's recommendation for gear oil and then embarking on an hour long crusade for the truth, I've decided to run Torco RGO 80w90 in my 'new' rear end. Why?
Eaton Literature said:
Detroit Truetrac High quality mineral gear lubes are required for use in Detroit Truetrac differentials. Regardless of the lube type, always use a GL5 rated lube with the least amount of friction modifier. Mineral lubes lacking friction modifiers (limited-slip additives) were historically recommended for all Truetrac applications because friction modifiers can slightly reduce the bias ratio (limited-slip aggressiveness) of Truetrac differentials. However, to address the continually increasing power outputs of modern powertrains, many vehicle manufacturers have switched to synthetic lubricants as a counter measure for increased axle temperatures and prolonged service intervals. In general, consult the vehicle owner's manual for the manufacturer's recommendations for lubrication type, weight and fill volume. This will ensure lube compatibility with the seal materials and bearings used in the axle. Eaton Performance technical support is available for any concerns in lube selection.

A quality petroleum (mineral) based oil is recommended. Synthetic oils and friction modifiers should not be used, as they will decrease overall performance.
Clear as mud right? The general consensus from Eaton Tech support is that their Truetrac diff *will* work with synthetic gear oils BUT will have a lower friction bias when compared to conventional oil. Thank you google.
Also, I need to strip it, clean it and POR 15 it prior to installation. Which shouldn't be too difficult but I only have about 30 minutes in the evening to do so. I have at least 9 more days to go at work but I'm on call that weekend too.
*sigh*
