A bad wheel bearing will typically make grinding, whining or squealing
noises, and you can often feel the looseness or roughness if you raise the
suspension and rotate the wheel by hand. I felt nothing before or after
repacking the bearings.
Your guess is as good as mine. I maintain all my vehicles. What others call
or do maintenance is just a guess. You are taking them on their word.
Boat trailer bearings are subject to possible water intrusion each and every
time they are in contact with the water. Water is the main cause of bearing
failure. Therefore, it is imperative to protect these bearings. One should
remove your wheels and inspect your bearings and seals on an annual basis.
Most don't they just give-em a squirt of grease.

You pulled all 6 wheels and inspected the inner and outer bearings on all
of
them? Then repacked all of them? Pardon my scepticism but it would be
pretty odd for a wheel bearing to go from passing a visual inspection to
locking up a wheel in one trip.

Well I bought a used 6 wheeled trailer 9 years ago. I pulled the wheels
and
checked the bearings. Even repacked them. Checked the grease seals. On
the
way home I had a bearing freeze. Thankfully I didn't have a load on the
trailer. After two days I was able to get back and replace all the
bearings,
grease seals, and the spindle that was ruined. I haven't had a problem
since. We still load the trailer up to the max 10,000 lbs. every week.
What
it really comes down to. Was the trailer maintained properly.

It is extremely easy to tell if a bearing is bad or not with a visual
inspection. I don't replace good parts. You don't even know how old
the
trailer is, how much it was used, or if it even was used in salt
water.
You
just offhanded recommend replacement with no other info about the
situation.
Does that sound like well thought out good advice to you?

Besides it's a lot cheaper to replace the trailer bearings than a
hub
that's
been ruined. Not to mention the peace of mind knowing that you
won't
freeze
a bearing going to the ramp.

You di that with every car you buy? Same bearings, a lot less
use.
Nothing
wrong with pulling the wheels and inspecting the bearings. If
they
are
bad,
and it's pretty obvious when they are then replace them. You
won't
hurt
anything if the grease you added was wheel bearing grease.

I bought a used boat and trailer, and before towing I noticed

Regardless of the grease problem, the best thing you can do
with
a
used
trailer is pull the bearings, toss them, and replace them with
new
bearings. All it takes is a few bucks and modest mechanical
skills.

Why take a chance?


I usually don't back my car into salt water over the hubs and then
let
it sit in the parking lot for eight hours or more while I go
boat-riding. Nor do I subject my car to the kinds of abuse the
typical
boat trailer sees.

New trailer wheel bearings are a small investment that help assure
safe
operation.
