| Has anyone used a synthetic wheel bearing grease?
If so, do you think it is better than
Molly or other type of wheel bearing grease? |

| Its been my understanding , the grease should be a high heat grease designed for bearings. I went with one of the recommended types in my owners manual. You can't go wrong if the manufacture recommends the type |

Location: western PA | Synthetic grease is the best type that is currently available for wheel bearings.
It has a high shear rating, will lubricate in cold temperatures and not run out when hot. Modern aircraft have used it for decades, with temperature extremes alternating from sub zero to boiling, occuring in only a few seconds. Petroleum based products cannot protect the bearings under those circumstances.
Synthetic grease also won't wash out easily when exposed to moisture. Boat trailer bearings are commonly completely water immersed after running hot at highway speeds. This sucks water into the races and bearing cavities. The end result was often seen with trailers parked along side the roads with wheels missing. Often times the petroleum lubricated bearings were repacked after every immersion, before any future trip was effected. With the advent of "Bearing Buddies" and synthetic greases, bearing failures are now a very rare occurrence.
The synthetic grease only costs a few cents more than petroleum products when bearings are repacked. Because the service life of the bearings is increased, and the maintenance schedule is greatly enhanced, you will save money using these products. This also holds true for synthetic oils. |

| Thank you for your response to my question. I cleaned my bearings, wheel hubs, and ez lube void of all the grease and went back with Mobil 1 synthetic.
Thank you again |
