My father-in-law gave my boy a 1999 350 Big Bear. It's been sitting in a barn for a bunch of years. It runs great! My boy has been riding a couple weeks now and it has developed a squeal coming from the front end when you get off the gas at speed. No noise during acceleration. At first I thought brakes. I took it for a ride and I don't think it is the brakes. I feel it is the front prop shaft U-joints, front differential or one/both axles. I pulled the fill plug on the differential and I can't find anywhere how much gear oil should be in there. My gut says up to the fill opening. It doesn't have a manual. It's wet in there, just don't see any gear oil.
#1 Should I fill the differential with gear oil up to the fill opening?
#2 How do I check or know if the u-joints are bad? That looks like a "Big Bear" of a job if they don't need to be replaced.
#3 What else could it be? I don't think it is the front bearings. I jacked the front wheels off ground and no play in the right wheel. Very little play in the left wheel, looks like the lower control bushing is where that play is coming from. The rubber CV boots look original but all still intact. Wheels spin easily without any noise.
Thanks for any help!

If you're getting that pesky leaky seal on the pinion of your front differential and the pinion has allot of play, polaris won't sell the bushing needed to repair it properly without having to shell out big bucks for the complete ring and pinion kit.
I have a kit with an upgraded bushing, Japanese made bearing and USmade seal
50 shipped in the US and 55 to Canada
Here is what I have collected over the years and maybe it will help someone else.
There are so many and several are too large to upload as attachments, so see any thing you need just shoot me a PM and your email and I will get them on the way to you as fast as I can.

Recently bought my BB. Everything works great. Only thing is, each time I put it in reverse, it either starts to rev high and start moving without giving it gas or I'll give it a bit of gas and let go and it will still rev at the same rpm or higher and keep moving. Doesn't do it for high or low.
