Bearing Buddy Recommendation for Fitting Hub with Bore of 1.98 Inch

Question

Question:

I am looking to buy some bearing buddies for my Travel Trailer. The axles are Lippert 3500lb axles NV# 121033. I have measured the dust cap with a caliper and it is 1.98 inch give or take a thousands. Would these be the correct bearing buddies BB1980A I am not sure what the outer bearing models are. Also what hi-temp wheal bearing grease would you recommend. I have read that you should not mix different greases. Currently it looks like the basic dark gray/black grease. Thanks for your help.

Since your hub bore measures 1.98 inches the correct Bearing Buddy is the part # BB1980A that you referenced.

The best hub grease is the "Red" grease like the Lubrimatic LMX part # L11390 which is the most durable and is compatible with basically all hub greases.
