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!

First time using this forum. Owned a Kawasaki dirt bike once, had no issues. But I picked up this 4 wheeler at an auction. They stated it ran, but only needed a battery. Well I do not believe that was all true.
Some pictures are attached. Not sure why, but the whole air filter stuff was removed. They had some small thing inserted as a make shift air filter.
I purchased a battery to try this all out. Waiting to return it and get the proper size, as it was too big for the battery box. But here is my issue I had while the battery was connected.
1 - The lights on the steering column did not come on. Not sure if they work or not.
2 - The starter solenoid seems to be bad. I have a new one on order.
3 - In the pick, there is another rusted part. Not sure what that part is or what it is used for.
4 - What is the 12v rectifier? square bodied part.
So when I hooked the battery up. Pushing the start button did nothing. Pulling the cord to try and pull start, it turned, but would never fire. I have put in a new spark plug as well, it looked worn out. With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.
I have read a few other threads and it stated something about needed the neutral light on. SOmething about a kill switch.
Any help would be appreciated.
Disconnected the plow yesterday on my 2004 Yamaha Grizzly 660 and am getting ready to do some riding yesterday and the battery went weak, Starter cranked a few times but week. Put my trickle charger on that I bought and went to the garage today to start it up, but the starter is just spinning and not engaging. The solenoid is clicking. The pull start sucks and is hard to pull (never use it and need to look into that). Quick video of the starter spinning. Could it be the starter or the starter clutch one-way bearing? I guess I need to take the cover off to see what's going on.
