Great trailer, I have a 2010 TC-16. You'll need to take the tire off to remove the dust cover.

 

Great trailer! I just did mine a few weeks ago. I had to use a scribe or a small screwdriver to pop off the plastic covers. Then used a small flathead to take off the rubber boots to get to the quick zerts. I didn't have to take the tire off when I did mine. Just be careful the should pop right off.

 

Yep-----Black cap will pop off---then remove the black boot covering the grease zerk. Use a small thin flat blade screw driver.

As state above, either remove the rim/tire or pop the black plastic cap to access the Zerk. If you're planning on repacking the bearings then removal of the rim will be necessary.

Bearing/Seal service is relatively easy to do if you've done some wrenching before. There will be a "keeper" that prevents the nut (holding the hub onto the axle) from backing off. The "keeper" pops off with a small flat screwdriver and then the nut will come off. Once you remove the hub there will be two bearings (one small, one large) and a seal in the back of the hub. I usually clean and repack the bearings but replace the seal annually. I only replace the bearings if they seem rough or discoloured from heat.

More than likely you will have Dexter axles on your trailer, so here is the service guide from them. Start reading on Page 45 for the instructions on greasing.
