True on the grease and keeping it in there BUT...there is such a thing as putting too much in one. The biggest problem with grease that I deal with is the fact that some people just put too much in them and cause the rear seal to blow or start leaking. Most end units, have a indicator cap. UFP uses a Chome one with a blue inidcator. If the blue ring is all the way in, you need to add some grease but only enough to get the ring moving outward. DO NOT FIL IT TIL IT STOPS! Those caps are there to collapes and expand as they heat and cool down. </p>
Oil Bath...theres the way to go. Runs smoother and cooler. Tiedown is the only one to use a TRUE triple lipped seal. There are converstion kits you can get from them. (Grease to Oil) but you need to make sure it has the stainless spindle ring with it. Your gonna need it if you go from grease to oil. </p>
Grease should be changed every year if you are using the trailer ALOT! 2-3 times a week. If not and you store it during the winter. Get the axle off the ground. Block it up so you can spin the tires every now and then. </p>
Oil bath...just watch the level of oil and color. Dont look for a leak in the front of the hub. Most likely it will be covering the back side of the rim if you have one. Grayish white color for the oil is also normal. Dosent mean theres water in there. The heat and quick cooling of hub can cause discoloring. </p>
I could share so much with everyone about brakes, hitches, actuators, hubs, bearings, runners, cables, tires.... you name it. </p>
