Ive got a 2018 Rubicon, ive had it almost a month its got 350km on it. at around 200km i noticed a slight squeak as i was slowing down, it seems to only really do it in 2wd it sounds rotational so i was assuming brakes? i cant be the first one to encounter this as these bikes havent changed since 2015 right? ive checked fluids in diffs etc and all seems fine. could it be something wearing in?

This rubicon isnt a swamp quad it lives on trails with a bit of mud and water rarely over the tires

best advice is try and better locate the squeak, try rocking atv side to side at each corner, , could be shock bushings
OR< get all 4 wheels off ground and run atv and use brakes and see if you can find sound better
wouldn't be impossible for a wheel bearing or bearing some place to be dry, seen a lot of brand new one's have little to NO grease in them,
do you ever use a power washer on this atv, if so, this increases the odds of a bearing going bad, power washers are BAD to use on ATV's IMO!

My rear brakes are horible they are noisy also,I was thinking about looking into different pads.

Hi: The squeak is most likely the brake shoe pins -- remove the pins clean them good replace them dry -- oil or grease will pickup dust and dirt which will cause that squeaking as the pads move in and out on the pins.

Brake pins etc are mentioned above.. Use copper grease/anti seize grease on all brake components that move, obviously not friction materials/surfaces!!
