Royal Purple 75w140 question

[kil roy]

getting ready to service the rear differential in my 01-job2

with 4.10 limited slip and have a couple of questions

that i did search for so as not to offend anyone but i

couldnt find the answers to.



#1 exactly how much does the rear diff hold?



and



#2 i see that royal purple has limited slip additive

already in it. is this sufficient or should i pick up

a bottle of the ford additive.



thanks in advance for the answers.

This is the RP that you want to use:



Max-Gear is recommended for use in truck, motor home / RV, and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid.



Max-Gear is an ultra-tough, high performance, GL-5 automotive gear oil designed to provide maximum protection to heavily loaded gears while maximizing power output throughout the drive train. It outperforms other GL-5 gear oils because it combines the highest quality synthetic oils with Royal Purple's proprietary Synslide additive technology.



Max-Gear makes gears run smoother, quieter, cooler and longer without overhauls.

#1

Front diff = 1.8 QT (1.7Liters)

Rear Diff = 2.75 - 2.9 QT OR (5.5 - 5.8 PTS) OR (2.9 - 3.1 Liters)



#2

I never trust the additive that comes with the oil, I always add my own.



P.S This is all in your owners manual Around page 200 in the Maintenance and specifications chart.

thanks for the information. i bought 3 qts of the max gear

figuring that i would need close to it plus whats left over

i will save for when i service the front.



i will pick up the additive from ford for the job then

just to be safe.
