Equal-i-zer hitch history

[Jeffjeeptj]

Has anyone seen an older Equal-i-zer with grease rittings on the hitch head in the area of the sockets where the load bars insert?

I bought a 6000 pound E4 hitch as recommended by the trailer dealer. The “song” the E4 hitch sings as we turn and travel bothers me (an Engineer). I bought the “jackets” that fit on the L brackets and I loosened the sockets on the hitch head and pushed some grease into the areas indicted by the instructions. This did reduce the volume for a bit of time.

I removed the sockets today and discovered a depression in the hitch head that is duplicated on both sides. I sent a question to the Equal-i-zer people today about these depressions. Have not heard back yet, as it is Sunday. I am thinking of using these depressions as locations for adding zerk fittings to the top of the hitch and some similar location for the bottom.
Has anybody seen this done, had success, too weak, etc.
Thanks in advance.

I added the jackets and also removed the pockets to lube them with axle grease as stated in the instructions for the hitch. It quieted the hitch down. I was very surprised that the hitch was dry and had no grease whatsoever for the pockets.

I would think twice about modifying the hitch. If something were to happen it could be an issue for you.

I have 2 E4 hitches, and it doesnt have those 2 recessed holes in them.
