I just picked up my new grizzly, have only 10 miles on machine, I noticed it has a vibration in drivetrain when it is put into 4 wheel drive, My kodiak never did this, is this normal until it gets broken in???

 

i have a 02 griz and mine does the same thing. this is my first automatic and i thought it was the nature of it.

 

the grizzlies vibrate cause they are made for women.hahahahaha[img]i/expressions/face-icon-small-happy.gif[/img]

 

Nice one , LMAO.

The reason they vibrate and are noisy is that they use square-cut gears, which are stronger than helical-cut gears. But the trade off is more noise and vibration, which is why they don't use them in vehicles.

 

I don't know about what types of gears, i do know that mine vibrates when placed in 4x4. I also noticed that it vibrates less when in 4x4 lock. It's not that bad and you get used to it quickly. I suggest that you utilize your 4x4 only when you need it. Thats what I do. I believe what may contribute to the vibration is the fact that when we place our grizz in 4x4 it is direct true 4x4, no rear wheel slippage needed. Just a thought. Vibrations are minor compared to broken rear shafts that other companies are expierencing.

 

I was going nuts trying to figure out this vibration thing on my 02 Grizzly I even went so far as having my dealer put a new diferential in the front end. He did so under warranty but the thing still vibrated really bad when in four wheel drive. There was absolutely no vibration at all in 2 wheel drive. I was going nuts so one day I checked the air presure in my tires and they were pretty uneven 2 to three pounds difference so I put 4 pounds all the way around and noticed an improvement but still the vibration was there. I layed in bed one knight and had an appiffany that sat me sraight up in bed with sweat rolling down my face I woke up my wife and haulled her skinny *** to the garage. It was 2 AM she was not happy. I got out a 2 foot level and got my fat *** on the bike and had her hold the level on top of the tires while she added air to make them all the exact height with me on the bike. This took some time as she is not to mechanically inclined. Not to mention she was more than a little pissed. In the end what I found out was shocking I had to run almost 2 pounds more air in the rear tires to get the same tire height. Mind you I am a pretty large chunk of meat weighing in at 287 pounds but there is absolutely no vibration at all in this quad anymore. If you understand the principal of travel per revolution you can understand what 3/4 of an inch difference between the rear and front tires can mean when the tires are traveling different distances while turning the exact same RPM. Most guys with this problem need to look real close at their tire pressure and the height of the tires while the Quad is loaded. Low pressure tires will have a circumference difference of a couple of inches with as little as 1 pound of air pressure. Now I know you are saying come on a couple of inches!!!!!!!! but beleive me when you are talking tires that run on 4 or 5 pounds of air it does make a big difference. Still think I have lost my mind check it out you wont be sorry tire pressure is almost always the culprit in these situations.

 

dude, if i did that to my wife, i would have been left in the yard with the dogs, lmao!!! i got to tell ya, either you have some great qualitys that make up for that one, or your wife is directly related to mother Thresa, lol!
