Question:

Im looking at adding BBs to my 35ft 8.5k travel trailer. Ive seen where you said to remove a bearing and get the number of the bearing. Also, seen where youve said to measure inside of hub with digital caliper. Id like to do it without removing the bearings. Is it ok the do the measurement instead of removing the bearing?

When it comes to getting the correct Bearing Buddy for your travel trailer you would use a Digital Caliper like # PTW80157, which you would need to measure the inner diameter of the hub bore, where the grease cap sits.

When choosing the correct Bearing Buddy you will want to choose one that is a few thousandths of a inch larger than the hub bore opening that you have.

I attached a review video link below, and a list of the Bearing Buddy parts we sell.
