Question:

I own a 2022 Grand Design Solitude 310GK and it’s time to grease the bearings. Looking for part numbers for seals and a spare set of bearings just in case.

Hey Ron, thanks for reaching out!

According to my research, your Grand Design has 7K axles and matches with the Bearing Kit # BK3-200 which comes with a grease seal that has a 2.250" inner diameter.

Is there anything else you're needing to replace/upgrade at this time?

Hey Ron, how did things go with the bearing kit for your Solitude? Did the kit fit your 7K axles as expected? Your update could make it easier for the next person doing the same maintenance.

Thank you Jon for selecting the correct replacement parts for my wheel bearing repack project. It was very simple to do and the parts you identified matched perfectly with what came new on the trailer. I have another project coming soon, replacing of the original suspension parts with wet bolts. I’ll be asking for your advice on which parts are better. Until then, thanks for your support.
