I just bought a new zero turn mower that has the same bearings as a typical travel trailer. It took 95 ft. lbs. of torque to loosen the nut. About four of the rollers actually had grease on them. So much for having professional mechanics do the work when even the factory has no clue.
It is so sad but true.
I've done mine for years, not that hard but yea, you can get your hands dirty but you can also use a bearing packer and avoid that.
I find with mine that they are about 10C above ambient when I shoot them with the temp gun. They should all be pretty close to each other but yes those in the sun will be a little warmer than those in the shade. If you can't hold your hand to the hub you're in the you need to do them now zone!
Lots of video's on youtube on how to R&R them. You WILL undoubtedly do a better job than any shop you pay to do it. A well packed/installed chinesium bearing set is way better than a domestically manufactured set that has been improperly installed and poorly packed. Don't worry to much about the source of the bearing, it really is the install that will make the difference.
