HORUSDY Premium Wheel Bearing Packer Tool, Handy Portable Bearing Packer Kit, Effortlessly Flushes Old Grease and Repacks Wheel Bearings

I have another cone-type bearing packer for use with a pneumatic lube gun.  It works well when the fitting doesn't leak, but the grease goes everywhere.  I thought this being packer might be a lot neater, and it is... sort of.  You still have to take the bearings out of the grease, so you're going to get greasy no matter what, but it least it's confined mostly to the tub.  The problem with this packer is that you have to press VERY hard to squeeze the grease through the bearing, and being plastic I'm afraid it's going to break if I press too hard.  I suspect that some grease might not be as thick as what I'm using, and perhaps enlarging the holes that the grease passes through might help, but so far, it's not the great tool I was hoping for.  I'm going to try drilling the holes larger and will update this review if it works.EDIT: After using it a couple times I've found that I can stand on the plunger to get the grease to push through the bearing. So far it hasn't broken, so I've added a star to my review.

Packed 8 wheel bearings for my 7,000 lb RV axles and it worked great!

So easy to use! This made packing the bearings with grease mess, free and ensured that they were packed properly! This is an awesome tool and I would not hesitate to add it to your arsenal for trailer repair.

Impressed, worked as well as my old lisle one and for half the price! Would highly recommend this bearing packer.

these bearing packers do a really good job of filling the bearing, but you have to push very hard to make the grease come through the bearing.
