My 2015 570 has starting squeaking when I turn the handlebars.
I’m assuming its the steering shaft bushing.
I was looking for grease fittings but didn’t notice any. Am I missing something or, is there are way to grease this?

Trying to take rear axle out for bearing replacement. One of the wheel hubs (wheel mounts to) is stuck. What is best method to get it off? Heat? Puller? Hydraulic press? Hammer? Other side came out piece of cake. Thanks.

28 9-12 mega mayhems?? Will stock 420 turn them?

So i was riding and the inevitable happened, my fuel pump went out, and i was wondering if i could buy a cheap $20 one online, or would a Vacuum pump be cheaper/easier to use? If i did go vacuum pump how hard would it be to install? My bike is a 1987 TRX350.

Hey guys, I just purchased my first quad. It’s a Polaris Sportsman 800 efi 2005. It’s in great condition, though there are what appear to be a couple minor things I need to take care of. Right below the compartment that houses speedometer, handlebars, and top light is a tube that runs down into the main body of the quad. This is my first quad so I don’t freakin know the names of any of these items and I have been searching for this forever. Any ideas what this is and how to fix it?

I’ve got this issue, where I redid the front wheel bearings.. and after tightening the axle castle nut, it goes deep enough that I don’t have room between the rotor and where the brake calipers mount.

installed the seals (front and back), reinstalled the whole "hub" back onto the machine.. then I slipped the brake rotor/assembly back onto the splined axle.

I have pictures of what I’m talking about, but I need like 2 more post to post it.

Any help would be appreciated.

Pulled the trigger on a Polaris 450 Ho EFI yesterday.
Old 300 Hinco was the chase unit with the drag racing and she was about on her last leg and falling fast so tickled about the new addition and toy.
GF and I do a little hunting so dolling it up for the two of us to enjoy, and looking forward to getting John at ATV-Guru.com new brush guard they are designing which looks way better to me than anything I have seen online to order.
I’m sure I’ll have lots of questions, but will be fun learning from you all.
Thanks and be safe
