Grease Guns

If you had your bearings serviced and they still burned out, it wasn't from a lack of grease. My guess is that whoever did the work did a poor job and probably over tightened the bearings when they were done. There are hundreds of posts on here regarding this issue.

B.O.

The problem with small grease guns is that the cartridges have limited number of types of grease. The axels on our TT call for a lithium based grease. Hand loading is messy. Pistol grip guns produce less pressure I think, but are much easier use as they are one handed.

I have a small grease gun but only use it on the suspension zerks and zerks on my riding mower.

What has your experience been in using a small grease gun to replace grease in wheel bearings?

I have my bearings repacked every spring and last summer still had bearings burned out. No doubt they were repacked improperly.
Our TT has "buddy boy" bearings set up so can easily apply extra grease in emergencies.

My idea is to carry a small grease gun. Any recommendations on type of gun that has worked well for you?

One my Buddy bearings, and I travel approx 8000 a year, depending on the weather hot, wet or just bad roads. at 2500 miles 1-2 squirts AND THAT IS IT, then at the end of my trips Iinstall NEW if I can find them US made bearings. and hand grease them prior to installation.
DO NOT OVER grease you Buddys you will blow the seals.

There's no reason to carry a grease gun for wheel bearings. Even at the higher mileages, once a year greasing/repacking is plenty.

The other this is, many TT's have grease "systems" if you will, that allow you to basically flush the old grease out and replace with new. No repacking needed.

Check into what you have exactly on your TT before you go too much further.

The bearing buddies can get people in trouble. As mentioned, its more likely to blow out seals (which could easily go unnoticed) and contaminate brakes. They do come in handy on boat trailers, where they can keep a low, steady pressure of grease in the hub to keep water out at all times. Still, I would not say they are "needed".

As far as what type of gun to buy...well that's just personal preference.

I do not like or use grease gun on axle bearings

Folks have a tendency to pump too much grease using a gun ....then seals get blown and grease goes into brakes.

Hand pack after inspecting bearings. Do it yourself........not difficult job.
