I have purchased a Harbour freight trailer# 90154 4X8 . I would like to purchase Buddy Bearings for it. What bearing do I require as theirs does not work? Please email me the part number. Thank you.

I reviewed the online owner's manual for your folding utility trailer and no information is provided on hubs supplied, so to select Bearing Buddy protectors for it you will need to remove the existing grease caps and measure the inside hub bore with a precision dial or digital caliper.

You will need to measure to the nearest thousandth - to 3 decimal places such as 1.810. Once you know this you can use the linked page to select the Bearing Buddy set closest in diameter. You will also need to determine if your hub bore is threaded or non-threaded. Filters on the linked page will let you narrow the product results shown to those that meet your needs. For example, if your hubs are not threaded and you measure a bore of 1.800-inches then you can use chrome-plated set # BB1810.

Use caution when filling your protectors with grease; it is possible to blow out your inner grease seal if excessive grease/pressure is forced through the Bearing Buddy.
