Larry - One thing I didn't notice until just now: In the photo of Greg's carbon bed with the jeep on it, that is a model 670 truck. A much smaller and lighter cab/sleeper than your 860. Even with the composite bed, I would side with the other guys here that the weight on your steer axle with a jeep and no trailer may be a concern. Not to mention, when fully loaded with jeep and trailer, what is the weight on the truck, steer and drive? I would advise extensive research before incurring the expense of singling, only to be overweight on one or both axles afterword. -

We have over 40000 miles on our trailer in almost 3 1/2 years. I check the bearings for play at most campsite stops and check temps. I repacked 1 wheel to check the grease a year and a half ago and it looked like new grease. It’s a triple axle and a little over 28000 lbs. I might repack them in the fall just to do it and the site will make it easy to do it. I definitely do not do it every year just because the service people say to. How often did you repack the bearings in the old rear wheel drive cars? Usually when the brake pads wore out.

However trailer bearing should be inspected annually for defects. Well, unless you're the kind that waits for a bearing failure first. And todays wheel bearing grease will settle out over time. I've seen it with one of my farm wagons that sat in a shed for 3 years. I removed the dust caps to see if they had any grease showing and oil ran out of the dust cap. Regardless of advertising all #2 non synthetic grease must meet the same specs.
