I would do too, but he just wants to get through the winter or two.
Wheel bearings are actually inexpensive, if you do the replacement yourself.
A few details need to be watched out for.
The races have to be seated correctly, otherwise you'll have to adjust after a few thousand miles or even replace them again.
I have seen shops, put in bearings just with the storage lube, they ceased, of course, after a short while. Now you're in trouble, to get it off the shaft.
I ran even across Mechanics, that looked at me like? when I mentioned packing the bearings, with bearing grease.

Guess that shop is not in business any-more?
