Can you put too much grease in a wheel bearing?
Too much grease volume (over greasing) in a bearing cavity will cause the rotating bearing elements to begin roiling the grease, pushing it out of the way, resulting in energy loss and increasing temperatures. This can result in accelerated wear of the rolling elements and then component failure.

How much grease should you put in a bearing?

Why is my Bearing Buddy leaking grease?
Typically Bearing Buddies are used on boat trailers to keep water out of the hubs. Since boat trailers are not often used in extreme cold weather this may be why we have not heard of thermal issues like this. The most likely cause for the seepage of grease out of your Bearing Buddies is overfilling.

DO NOT CONTINUE GREASING ONCE YOU SEE THE BOOT SWELL. The seal that holds that grease in the ball joint can be compromised if too much pressure is applied. If this happens you will be replacing that part sooner than later.
Should bearings be packed with grease?
The housing should normally be 1/3 to 1/2 full of grease during bearing assembly. Too much grease in the housing may cause high temperatures and excess churning of the grease. Proper lubrication greatly increases the life of bearings, especially in adverse conditions.
Can you over grease equipment?
Over greasing is also to blame for seal failure and damage. Because grease guns produce up to 15,000 psi, lip seals can rupture allowing contaminates to enter the bearing housing.
Can you reuse a Bearing Buddy?

Why is there grease all over my trailer wheel?
Expert Reply: It sounds like the seals have failed and the grease from the bearings has come out during travel. Also it is possible that if you have an EZ lube axle with a grease zerk at the end to add grease but use a single lip seal, the pressure can blow out the single lip seal.

How do you know when to stop greasing?
Measures to Follow
You can also avoid over-lubrication by practicing the following measures: Stop greasing if you note back pressure that is not normal. Check to see that the exhaust ports on a machine are free from debris, including hard crust. Slowly pump the lubricant into a machine’s bearings for several seconds.
How do you clean Bearing Buddies?
Remove the inner bearing. Take the old grease out of the hub and clean its interior. Wipe the old grease off the spindle, hub, bearings, races, and cap, keeping any eye out for metal shavings that would indicate bearing failure. Then clean any remaining old grease off with parts cleaner.
