[QUOTE="hammer33, post: 5744783, member: 19900"] Put it on your calendar. 1x a year jack the trailer up and check the wheels for wobble, and spin. My mechanic told me you want no side to side wobble, and the wheel should spin freely but with just a little drag. You get this by the tightness of the castle nut. Next is the seals. When you pump grease into the fitting, does any water come out? If so, plan on taking the hub off and inspecting the axle shaft, the sooner the better. Water and heat will break down the grease quicker and the resulting mud doesn't lubricate well. The water will also work on pitting the bearing surfaces. If you catch it early before any damage, you can clean the bad grease, replace the seal and grease and be back on the road. If you let it go all season, you will probably be looking at a rebuild if not a new axle. Saltwater dramatically increases the damage. Grease. putting a little squirt of grease in the fitting does 2 things. Tops off the grease if you used any up or have a leak, AND it will show water if you have a leaky seal. If your seals are good, you probably don't need to add grease 1x a season, BUT if you have a problem a 1/4 pump of grease is often all you need to determine that something is going on.

You will get a huge mess on the rims which is very hard to clean off, unbalance the tire with the goo, and the water damage to the axle and bearings will surprise you.
