Wolverine clunking noise! Help!

Recommended Posts

So I have a 1997 Yamaha wolverine 350 4x4 and am experiencing a clunking noise at low idle and it only happens at random. It seems like its coming from the lower end. Engine seems to hesitate when it happens. And ideas!? Thank you

I checked the starter clutch and it seems to be working properly. It's coming from inside the case towards the front on the right hand side if you were to be sitting on it. Looks like the only way I may find out is by opening it up. I do plan on re-building the top end this winter.

Hmm, It strikes me as odd that it only happens randomly. Id be eyeballing thing that change their mechanical position in a different manner after each start-up. Could the flywheel be loose? Maybe the stator plate screws loosened up? Exhaust pipe cracked or loose causing a random leak? Id be checking external stuff before jumping in & cracking the case upen. In my experience a bad crank bearing or something like that usually doesnt go away then come back. Good luck with it though.

      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. 😎

      2012 Rancher ES-- only when driving in 4x4 when I get to about 15-18mph there is a loud clunk in the front end and a hard downward jerk. Its almost as if its trying to downshift itself. It doesn't do it in 2 wheel drive.  I have checked the angle shift sensor and applied dielectric grease to it, changed the front end differential fluid (the old still looked good and clean) checked and adjusted the clutch. Hopefully someone can give me some more ideas.

      I am having an issue where it sounds like the gears are slipping if I hit the throttle really hard and also after letting off when the engine brake is applied. Also, the drive train that goes to the front also rides again the gear shift box. I will attach pictures and a video here shortly.
      Thanks in advance!
