Question:

I have a Grand Design MAV24. Is there a Timken bearing kit that I can purchase? Thanks!

Hey Brandon,

Unfortunately we do not have a way of knowing exactly what bearings came on that Grand Design by just the model. I did however try and do some research on that trailer and it is so new that I cannot find any confirmed specs on it! With that said you are going to have to remove a wheel and hub and either get part numbers or measurements to determine what is needed. I have attached a photo for you that shows where to find bearing numbers or measure to get the correct size.

Are you wanting to just get a set up replacement bearings to have a backup?

Hey Brandon, were you able to pull a hub and find the bearing numbers or measurements for your Grand Design MAV24? Knowing what you found could really help others trying to match Timken bearings for the same trailer.
