bearings and tires
This past weekend, I replaced the wheel bearings and got new Sailun 637's installed. When taking them apart, one of the brake assemblies was in pieces and there were some bad gouges in the hub. today I picked up and new brake assembly and hub so I can finish it up.
A good reason to take apart and inspect every year!

Agreed. Good thing you caught that before it got worse.
I did the same when ours was only about 7 months old and found the magnet in pieces and the wiring wrapped around the axle inside the hub.

Wow, 2020 and tires, bearings and brakes. How many miles on the rig? For future reference on expected repairs.

I know your question was to Jim, but ours was at 7 months and had around 18K miles on it. I didn't need new bearings, though. Mostly wanted to make sure they were greased properly. I saw numerous posts of new rigs not having any grease in bearings.

Just inspected brakes, replaced grease seals and repacked bearings on one side. Gotta do the other side this week.
Picture is of Dexter original grease seal (green ones on the left) and Timkin grease seal (orange one on the right).
Very significant difference.
I will be buying Timkin spare grease seals and bearings.

Having used Dexter OEM DL 10-36 grease seals for 8 years now I see zero issues with them.. The Dexter OEM inner/outer bearings and races look as good now as they did new 8 years ago... over 37K miles on the bearings...
What is the significant difference in the Timken? and yes.. I well know the Timken name but they aint.. in some cases made like they were years ago...

Yeah, every year they should be inspected. Ours had only about 6,000 miles on it and when inspecting I found a rear seal blown and axle grease all over the brakes.

I have about 6000 miles on it. For the cost of bearings and seals, it is easy to replace when it is apart. As far as the tires, the OEM tires are not rated really high and we are planning on some longer travels this winter and spring and wanted to reduce the chances of issues on the road. Anything can happen, but it was partly piece of mind for me.

A sad reality of today's manufacturing environment is that name brands that used to be our go to source are pretty watered down now days. Timken has plants in the US, China, India, Taiwan and Romania. Look on the box for (USA) before you shell out the extra money for the Timken name ... several of our common bearings and seals are currently made in India or Taiwan and it says so right on the boxes.

Bearings
I need to replace all the bearings on my 2818 3811MS but haven't figured out how to remove the rear bearings yet. Is there a special tool that helps or do I use a screwdriver and hammer?

I'm guessing you are referring to the inner bearing. Once the seal is removed from the back side of the hub, the bearing should fall out in your hand. You can get a seal puller tool or just use a screwdriver to pry the seal out. Make sure you replace bearings and the races as a set. They are matched for tolerance.
Just curious...How do you know you need to replace the bearings if you haven't removed them and inspected?

Before you remove your bearings to inspect them, make sure you have new bearing grease seals. When you pull the grease seals to get to the inner bearings, they deform. You cannot re-use them.
After you repack the inner bearing, install the new grease seal by placing a block of wood flat across the back of it and gently tap it in evenly until it is flush.

I would recommend getting a bearing race and grease seal installation kit. Harbor Freight has them and not that expensive. Saves a lot of headache when I stalling the races and seals.

I agree, it is on my list. Just could not do it right now.
