how often should you check the fluid?
I have a 2018 and never have
I had it serviced at the dealer a few times but am I supposed to ask them to check it or is it normal for them too when they do an oil change
I check mine a couple times a year but I've had 2 seals go bad and I am under mine a lot as it basically lives on a lift unless I'm driving it. The dealer will not check that during routine maintenance as Polaris doesn't even say it's first replacement is needed until 50k, 100k, 150k miles. I would imagine they would if you asked though. A lot of us have changed ours out with different gear oils to help reduce the whine of the angle drive. There are a lot of choices out there but I am a fan of Redline Shockproof Lightweight. I've also seen a lot of people use the heavyweight version as well which is also a great choice. I like the lightweight because it is bright blue and easy to spot if there is a leak.
