🔧 CURT 22178 Trailer Wheel Bearing Protectors and Dust Covers - 1.78-Inch (2-Pack) Review

This is a great investment in your trailer. Advice for you to install them. Just take a small amount of grease and lubricate the outside of the bearing guard, then you'll find a bigger head. I think a 1 1/2 head is the right fit. Align the bearing guard and move the seat into a position where you can hit the seat with a hammer and insert the bearing guard. Apply some lube and you're good.

later This protective bearing grease (as others have said) is slightly off spec - enough to make it impossible to do without damaging something. The part diameter mentioned should be: 1.781 inches, but they are 1.7845 inches and 1.785 inches, respectively. I hope this review will save someone else the trouble of wasting their time and money. Instead I use Bearing Buddy.

Wrong size ordered. Then I remembered that I had recently ordered a pair that I hadn't used (same brand) and they were the right size. At least that's what my caliper said. Tried it with a hammer, didn't help. Attempting to smash them in with a regular hammer using a block of ultra-high molecular plastic for protection didn't work. I tried making more bevel on the leading edge, it didn't help. I've tried tapping the armature directly and gradually hitting it harder and harder, didn't work…
