Depends on when they were made. It never used to be a maintenance item years ago. Then HD cheaped out and went with a shitty vendor and now there are failures. When I had my 2015 SGS I heard it was an issue with the Rushmore bikes and when I powder coated the wheels, I installed a good set of MADE IN USA bearings.
Read many 'horror stories' on here, seems many experienced guys state its due to folks using powerwashers when cleaning their bike which gets water into the bearing etc.
From reading HDF I have learned....overpacking a new bearing w/ too much grease can be worse then not having enough grease.
Also, 'mixing' greases can a bad idea as the compounds may be incompatible.
The horror stories got me to purchase the Pit Posse bearing tool and swap mine out some time back. One bike had 40-50k-ish and the bearings were ok.
Now will plan to do every other tire change or so. multihdrider (sp?) is a good source for bearing info if you search for his posts. Haven't seen him on here in awhile.

I think I will copy you on the every other tire change or so plan. With a lot of stuff I think there is an ideal replacement interval based upon wear & initial high failure rate (installation defect, fabrication defect, defect in materials), since I don't have a clue what the ideal interval would be for front wheel bearings on a Road King I will go with what feels good.
Just understand that every time you remove and install a new bearing in the wheel, you slightly wear the wheel, making the bearing race fit looser and looser in the wheel.
My front 25mm bearings lasted a whopping 2500 miles. My youngest brothers lasted about 12,000. So it's a crap shoot.
Every time my wheels come off for anything i inspect and pop off the grease seals and add some good grease. I am going to replace them at every tire change and keep myself safe.
Had a rear one fail on the low rider at 23k, installed a set of timkens to replace them with, on the Road Glide I changed them at 12k even though they were still good, installed a set of World wides in the wheels, Timkens in the rear sprocket.
I check 'em when I mount and balance new tires, if they roll smoothly, don't bind and don't make any noise I leave them alone. Never had a problem.
^^^^^What he said^^^^^
I install my own tires and bearings. Wheel bearings will last a long time IF they are properly installed. When I change tires I always check my bearings. If I don't think there's an issue I don't worry about it.
For those that have a tech install them, if you have the ability to jack your bike up and pull your front wheel, spend an hour and double check their work. Most likely all is well but that front wheel is pretty damn important to trust your life to someone else's wrench.
