Here is a table of bearing part numbers. It is an image and you may need to click to expand it or open it in another tab. I created the table in MS Word and ended up converting to a JPG image to make it easy to upload to various discussion forums. This site in particular resizes the image so it is difficult to read. I used the current Dexter catalogs for the bearing and seal part numbers.
There are two columns that have SET numbers. Generally when you buy bearings from industrial bearing and drive businesses they get the races and bearings as separate items. Timken does package them in sets of bearing and race in one package, and that is what the SET numbers are.
You almost certainly have 3500 lb axles and no matter if Lippert or Dexter the bearings and seals will be the same. If the table turns out to be difficult to read the numbers you will need are.........
The inner bearing (larger one) is L68149 and its race is L68111 (which make up SET17). The outer bearing is L44649 and its race is L44610 (which make up SET4). The seal is National 473336.
Timken bearings are found on Amazon, however, Amazon has a lot of problems with bogus and fake parts and Timken bearings are commonly faked. Stick to known suppliers. To save money, I recommend purchasing the sets from Summit Racing....
https://www.summitracing.com/Generally shipping is free on orders over $99 with Summit so if you order an entire set of bearings, and National brand seals, throw in a tube of grease, you are over $100. If you buy from the Industrial suppliers, you will pay over $160 for the same bearings. However if you only want one or two, that is the way to go. You will most certainly have China made bearings and I highly recommend replacing the entire set of bearings and races with Timken. Just the Summit site for SET4 and then for SET17 and you will get them.
You will need a set of bearing race drivers to install the races and you can purchase the drivers from various tool businesses or borrow them from most auto parts stores with a deposit. Make sure the set is complete. You will need a large wooden block and also a 2 lb or so ball pein hammer, and a 10 inch or so drift to punch out the old races.
For packing the bearings there is nothing easier than a good bearing packer...........
https://www.amazon.com/Lisle-34550-Handy-Packer-Bearing/dp/B0002NYDYOAnother bearing packer I can recommend is this Gearwrench branded one (I own the same packer Snap On branded, in addition to owning a Lisle packer)
GEARWRENCH Hand Bearing Packer - 2775DFor grease I prefer a synthetic grease with Moly in it, such as Valvoline Moly Fortified Full Synthetic grease (2.5% moly).

Don't bet on all Timken bearings being made in the USA !
Indeed they are not, however in my experience purchasing a couple of complete bearing and race sets thru industrial suppliers, and another couple of sets thru Summit Racing, (all 3500 lb axle sizes) they were all USA made. National seals are a division of Timken and the seals have varied, some made in Mexico and some made in Taiwan. In any case you are assured of a quality standard well above anything else. Toyo Koyo is another quality manufacturer I can recommend.
