Does anyone know where these can be found at? I am not having any luck on finding these. There was a lengthy post on replacing these but no answere on where to find them at. Any help will be appreciated!!!

Wow, a Hawk with worn out S/A bushings already? Couldn't be the S/A hinge bolt, could it. Many people do not grease that bolt when they assemble the machine. You checked the nut and washer on that bolt, right?

a little over 1000 miles on the bike and they are toast!! it could had been from the bolt not being tight enough not sure but bolt looks okay. Chain kept coming off and finally diagnosed it last night. drove the bushing sleeves out and riding around town looking for a replacement is not fun!

First place I'd go to is whoever sold you the bike. That should be under warranty. I have made these bushings before out of 1/2 inch hydraulic hose and 2 extra washers each side, but that is what is called a PITA. I had to make some for my 500cc Triumph brush jumper, as I couldn't find any anywhere. Of course the Triumph was about 20 years old when this happened, so I wasn't real upset.

Are the Hawk bushings the typical type, where there is a metal tube encapsulated by rubber?

Typically, they are vulcanised to the tube(s)

I changed sprockets today and figured I should check since it would only add a couple of minutes. Boy am I glad I did, my bushings were utterly barren of any grease. Mine is a new July 2016 model also. I lubed it and the rear shock connection before re-assembling.

The problem from what I've seen is that the inner metal bushing came out of the rubber inwards causing the swing arm bolt to wear away the rubber. Solution was to go to the auto parts store and buy some rubber hose to replace the damaged rubber and then cut a length of copper tubing to keep the two inner metal bushing from coming out.

These bushings look a lot like those found on GY6 scooters used to insulate engine vibrations at mounting points. I have seen them on scooter parts web sites and eBay.

Look at GY6 scooter engine bushing

I know these things are built on the cheap..
but rubber bushes in the swing arm pivot
that just screams nasty...

they had them on the boys pitbike.. but on a bike
like this.... why..
I machined bronze bushes & sleaves for it

if yer can't find bearing to fit...
cut the eyes out of the swing arm... machine new ones
to take bearings.. weld them back in....
that would be my fix anyway....

I far prefer Oilite bronze bushings for this job, with a loose fitting spacer tube between them, and a grease zerk installed in the center of the swing arm cross piece. Not the one the shock is attached to.
A well greased bronze bushing is very hard to wear out, and it improves handling by reducing the tendency of the rear wheel moving from side to side. Try it. You'll like it.

There are roller bearings that will replace those.Tho I'm not sure what size.I've never had one, so I'm not sure exactly how the rear swing arm is set up.The bearings need an inner race,aka sleeve,to ride on, and for the bolt to clamp down on, so the swing arm doesn't bind up as it travels up and down.
