Replacement Bearings and Seals for Curt 7k Axle

Question

Question:

Good Morning, I am inquiring on bearings and seals for the following axle Part Number. CURT Item 2024057204. What I am looking for are Timken Bearings. However, Ramblin Man RV indicated he likes to use a Dexter Double Lipped Seal, colored. So I am interested in purchasing those as well, as long as Timken bearings can be paired with another manufacturers seal.

Hey Matthew! Thanks for providing that axle information. I reached out to Lippert and for bearings you need the Timken # TMK44FR and # TMK75FR.

From what they said, your axle came with an oil bath setup so for the seal you need the Unitized Oil Seal for Trailer Hubs # 10-63. The Dexter double lip seal you're referring to is likely designed for a grease hub application, so you wouldn't want to use it with your setup.

What kind of trailer do you have?

Hey Cory, the Curt 7k axle you have would use the grease seal #GS-2125DL. Did you damage your seal or are you wanting to have a spare on hand? The races you would need are part #25520 and #14276.

It sounds like the remains of a double lip seal. Was it like a rubber o-ring with a metal spring around it? You are going to have to replace the seal so I would just disregard the sleeve. It would go on the outside of the rubber lip though. I…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
