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!
Got my Yamaha Grizzly buttoned up finally and went for a quick 2 hour ride in the power lines with my neighbor, who has a Yamaha Kodiak. We have access from his yard, which is nice. Was a beautiful day today to get out and will try to go more often. Ran into two other quad riders with a sportsman and I think grizzly. Also ran into a dirt bike rider. 😎
i have a 91 moto 4 100. has electric start only. for as long as i could remember we have always pushed start it. after riding for while you shut it off. you are able to hit the start button and it will start right up. anyone know where i should start with fixing this issue? im fixing it up for my niece. thank you in advance.

Blountville, Tenn. (April 21, 2012) – Round two of the AMA ATV Motocross National Championship Series headed to Muddy Creek Raceway for round two of the ten-race series.

Harold Goodman took the Moto 1 HoleshotThe ATVRiders.com Fastest Qualifier came from Motoworks/Can-Am’s Joel Hetrick for the second race in a row, as the young Pennsylvania rider showed some of the fastest speeds of the weekend. And ATVMX veteran Harold Goodman shot out to the Moto 1 SSi Decals holeshot, but it was Baldwin Motorports/PEP’s Josh Upperman who got into the early lead before Natalie moved into the lead by lap three. Wienen had a mid-pack holeshot but quickly put himself within striking distance of Natalie’s lead and the duo picked up the intense battle right where they left off at round one. Wienen stalked Natalie until the final lap and once again cut underneath the Ironman to steal the last minute lead and Moto 1 victory as the rain started to fall on the Muddy Creek Raceway terrain.
Hetrick got off to a bad start but put his Motoworks/Can-Am into the third spot around lap five and kept a comfortable cushion on Upperman, who finished in fourth. Thomas Brown struggled off the start, but worked his way through the pack on his TBROWN Yamaha powered by Moto-X-Perts, where he maintained a fifth place finish, just ahead of Lonestar/SSi Decals rider Nick DeNoble.
In Moto 2, Wienen took control early on, while Natalie settled into a close second and that’s how they finished. Hetrick started off in fifth place as he passed his way back into the third spot, gunning for the leaders that were less than four seconds away throughout the entire race. Wienen went on to secure his second straight win of the season, while Natalie and Hetrick grabbed the other two podium positions.

Wienen takes his second straight victory in TN“The new Yamaha is awesome, I’m starting to get more comfortable on it and especially in the mud today, I feel like I barely even rode the thing!” Wienen said. “It’s crazy to think that nine months ago I was laid up in bed and after a lot of hard work and determination we’ve gotten to where were at and I’m just having fun and paying my dues, taking it one race at a time.”
Although Upperman claimed the SSi Decals Holeshot Award, the Honda rider settled into fourth and maintained that position for the rest of the second moto, going 4-4 for fourth overall for the day.
Thomas Brown (YAM) finished with a 5-6 score to take fifth overall, just ahead of Joe Byrd (HON), who took home sixth overall. Nick DeNoble (HON) ended the day with seventh place, ahead of Derek Swartfager (HON), while rookie Mark Madl (HON) took ninth and Harold Goodman (HON) rounded out the top ten.
