The Grizzly has a high center of gravity, but it also has the highest ground clearance than most other quads. All these "weak points" you have mentioned can be corrected by stiffening up the shocks and changing to aftermarket tires and wheels.
In my opinion, the tires are the Grizzlies only weak point. The sidewalls are too soft and they don't self clean worth a ****.
You've got it. Try stiffening up the front shocks one notch. I use a pipe wrench and a piece of leather to keep from scratching the shok up.
New tires and rims and a slight shock adjustment and the Grizzly is perfect.
Most of the new after market rims will give you a offset making the stance of the Grizz a little wider, wich helps with the stablitiy issue.
Now for me I run without the sway bar and the shocks as soft as I can get them and end up doing quite a few off camber situtions when rock crawling and don't have a real issue with it being tippy, atleast any more than my Rancher I had. I have placed it in a few hairy places on purpose and just sat on it and moved around and rocked it some just to find out where I feel comfortable with it and get a feel for how the machine acts.
Do like Extremegrizz said and put yourself in some different situations and learn the charactoristics of the machine. You'll find that the suspension may allow it to sway, but it is very difficult to actually tip it over.
I believe it is fairly common, a simple search on Google will show the extent of the problem. A lot of people just change to Gorilla Axles.
With bigger size tyres, the axles break, with normal size tyres the CV's pop out due to a bad circlip design!
Changing to Gorilla Axles here would cost me 25% of the purchase price of the Grizzly, and I have standard size tyres, also the axles do not break, the CV joints pop loose from the diff. This would happen with the Gorilla Axle as well.
