Ring & Pinion Lube

Jim Wahl · 07-05-2012, 01:53 AM

I never realized how varied the opinions on this subject would be! It seems very much like engine oil. I got 6 PMs and not one recommended the same gear lube. All but one advised to use synthetic though. Now a question from you MoPar guys who use an 8.75 rear. How much lube do you use? The stock rear uses about 2.5 quarts. I have heard several guys say all you need is one quart if you have a spool. My red flag goes up when hearing that because you not only are lubeing the ring and pinion but also the axle bearings. I don't see how one quart would be adequate for that. Am I wrong? Jim
