What is your opinion on 80w-90 vs 75w140 for general use? (as opposed to 75/140 in the rear only when towing).
I haven't seen a recommendation for the PR44 either. Do you follow the factory guidelines?

Attention Axle Customer
This sheet contains important information relating to the completion of the axle installation, and safe operation of your vehicle. Please make sure you have read and understand the items that apply to your axle. We encourage you to ask questions and will be happy to take whatever time is necessary to answer them to the best of our ability.
WARNING: Always wear proper safety equipment including safety glasses and gloves while working with tools. Improper use of tools and equipment can cause injury or death.
WARNING: Only perform this installation if you are experienced, fully equipped mechanic.
General
• This axle is equipped with a:
Locking Differential Limited Slip Differential Open Differential
• The axle IS / IS NOT filled with the appropriate gear lube. We recommend Torco 85-140
GL-6 gear lubricant. If equipped with a limited slip device make sure the gear oil you use contains Friction Modifier for Limited Slip Differentials, and is rated for API Service GL-6 or GL-5 minimum. Change the gear lubricant after 15-20,000 miles.
WARNING: Choose proper gear lube and appropriate friction modifiers for your application. Set and check for proper gear lube levels in your axle after assembly and after driving for the first time.
• Locking and Limited-Slip Differentials can significantly affect steering and vehicle handling.
If included, read the owners manual carefully. Exercise extreme caution and always operate the vehicle in a safe manner. Initially only operate the vehicle at slow speeds in and out of
4-wheel drive to familiarize yourself with the new handling characteristics. Avoid moderate to high speed driving while in 4-wheel drive or when hubs are engaged.
WARNING: Locking and Limited slip Differentials will affect the steering and vehicle handling of your vehicle. Make sure you are familiar with your vehicle’s new handling characteristics both in 2 wheel drive and 4 wheel drive to ensure safe operation.
• Tighten U-Bolts to the correct torque for the U-bolt you are using. Check and re-torque
u-bolts frequently for the first few months or few thousand miles of driving. Replace any bolts that do not hold torque.
WARNING: Always use a calibrated torque wrench when checking and setting torque to manufacturer’s specifications.
• BREAK-IN - Ring and pinion sets require a brief break-in period in order to ensure long life and quiet operation. The following procedure is required to maintain any and all warranties that apply:
1. Bring the axle to normal operating temperature by driving the vehicle unloaded for approximately 20 miles. Do not accelerate hard or create unnecessary shock loads.
2. Let the axle cool completely.
3. Operate the vehicle normally for the next 200 miles. Do not haul heavy loads or tow heavy trailer during this period.
4. For towing usage, operate the vehicle with the trailer for about 20 miles, and let the axle cool completely.
5. Avoid constant heavy towing until a total of 500 miles has been driven on the new axle.
CAUTION: Following these break-in procedures can extend the life of your ring and pinion.

Would you advise that draining the stock Rubicon diffs at 1K miles and refilling front and rear with the Torco 85-140 as a good plan?
