Here is a tip, since you appear to have a vehicle with sealed diffs, spring for some 50k weight diff fluid and put that in the center diff. Much better than the best grease. Still use grease on the ring and pinion gears in the ft and rear diffs, and I like 30k diff fluid in the front and rear diffs. This is a great bashing setup for a truggy, and I used this with my heavy muggy.
Well....I can tell you this...the grease did not work. It did for a minute but after a while, no drive from the rear. No broken pins in the diff and initially the diff works but I want to see this thing run...I will JBWeld it this weekend.
