Hello, I recently ordered your galvanized for marine use trailer hubs that were pregreased. Could you please tell me what brand of grease is used? Id like to know so I dont mix the grease with one thats not compatible. Thank you, Tilo L Schmidt

Hey Tilo!

The CE Smith Trailer Idler Hub Assembly # CE13515 from your order uses a lithium complex grease like LubriMatic LMX Industrial Strength Grease # L11390. When you're maintaining your hubs, you can use the chart below to see which grease types are and aren't compatible with the lithium complex grease. What kind of trailer are you working on? Is it normally in an area with a lot of salt-water or road salt?

@TiloS That's great! This # L11390 is great in salt water and *mostly*, but you could go with LubriMatic Marine Trailer Wheel Bearing Grease # L54FR to replace the grease which is fully water insoluble and will last you longer.

@Bobby I'm happy to help you there! What size are the lights you're replacing? Are they spliced in or do they come with a plug?

I bought the same part for my Pacific trailer hauling a 1988 Montauk 17. I kept the grease as provided and experienced no issues. When I will eventually change the grease, I’ll remove the old grease and apply new grease so no compatibility risk

@John That's perfect! How often do you get to take your Montauk 17 out?
