I saw some information on the net that indicates that tapered roller bearing grease that contains moly is detrimental to tapered roller bearings. Fact or fiction?
Shoot, Jim, don't scare me. Here is what I've pulled from the CV-2 website: "Grease contains a red moly compound which is a superior lubricant to black moly disulfide lubricants." There seems to be a big difference between red moly and black moly and I know the black moly often gets a bad rap. CV-2 also states, "Red Line CV-2 Grease is designed to withstand the extreme temperatures and pressures which occur in high-performance wheel bearings and CV-joints. The excellent high temperature stability, extreme-pressure protection, and water resistance enables it to out-perform even the best conventional or synthetic greases." I know it is highly recommended among the automobile industry and enthusiasts. Anybody heard anything different?
Here's a link to the technical aspects:

Redline Moly CV-2 is about the best wheel bearing grease that is available. I race a vintage spots car and that is all we, and other racers, ever use in our wheel bearings and U-joints. The reasons is its performance at high temperatures. However, will other greases work for 5th wheel bearing applications - sure. Is synthetic grease overkill for trailers - using a litte better stuff never hurts - so you decide.
My friend who raced an IROC Z in 24 hr racing with two drivers recommended this grease. It was the only one that wouldn't run out when the brakes got smoking hot. I used it on my trailer before a long 27,000 mile 9 month trip around the country. I checked the bearings when I got home and they looked great.
