Check the caliper mount though i doubt it. It might be the brake rotor or hub mount itself. Its not hard to replace the rotor or hub.

Also I have a big problem with mud caking up inside the caliper. Make sure the caliper is clean and the slide pins are gunk free.

If the noise doesnt bother you leave it..

I`d check your Rotor first !! Calipers are hard to bend or break

i replaced the rotor and pads and cleaned the caliper def helped with some but not all the noise ....as far as my caliper wobbling i tightened the bolt that holds the lil mount to the caliper and with the new rotor and pads everything seems the roll nicely.....but decided to roll the quad while the caliper was off and there is still a noise ....... so the issue must be worn out or blown axle bearing i'm assuming ?

Its possible its the carrier bearings making the noise. Did you verify that the rotor hub is true?? If the rotor hub is bent the rotor will bend when its bolted onto it. How bad is the noise?

Last thing would be to remove the rear axle and spin each carrier bearing individually by hand to see if they are making the noise. If no avail post a video of the source of the noise

hey thanks for the help after finally getting around to fixing the problem it ended up being a blown bearing in the carrier it had a lone star dual bearing carrier in it witch i was not aware of because i bought it used ...3 of the 4 bearings were in ruff shape but still solid i believe thats why there was no play in the rear end ....there was also a crack in the carrier i imagine from the previous owner beating the bearings in so i have ordered an entire carrier assembly just waiting on it once i install it make sure 100% everything's good to go ill let you guys know thanks again for the help

      Answer to your first question ...
      YES, you can drive it anywhere.. on highways.. back roads... neighborhoods.. off road... ANYWHERE ITS LEGAL FOR CARS or 4-Wheelers !

      This took a lot of work and effort with many divisions of the transportation dept. and through multiple attorneys advice.

      This is one of only two 4 wheelers that are street legal in the U.S.A. (Excluding Montana, parts of Arizona, and New York).

      Now for the details.

      The motor is matching numbers to frame and title.
      The motor is 883cc beefed up to 1200cc.

      This bike has Super Swamper Vampire tires in some pics (THESE ARE NOT STREET LEGAL TIRES) and do not come with bike.

      This bike has STI Black Diamond Tires with black STI3 rims in other pics. (THESE ARE DOT APPROVED TIRES AND ARE STREET LEGAL).

      This bike also has ROAD Street Tires too....

      Hi guys I'm new to the forums and I need some help to make a decision. I recently started riding quads a few months ago and have been riding a Yamaha blaster. I'm now deciding of getting a raptor 350, Honda 400ex, trx450, or yfz 450. At first I looked into the 350 but I wanted more power. Recently I looked into the yfz and read it has a smoother ride and something about adjusting the cylinders? Any information on what I should get, pros? Cons? Would all be extremely helpful.

      Hi, just picked up a MOTO 4 YFM255 and want to replace the rear brake pads. How do I get to the back. Guessing I need to remove the brake disk, question any easy way to do this?
      Thanks

      When I push down on the rear brake pedal, it makes the left hand brake very sloppy. Is there a way to adjust that? I have a 2007 Suzuki Vinson
