wheel bearing ??

quite possible it is your axle CV joint going on that side.
I'm new to this quadding thing but if youve changed the wheel brgs the next would be CV joints.

I don't know if the 450 is the same, but on my 300 the inside of the knuckle where the bearing sits was actually worn out enough to the point of where the bearing can move just slightly, causing them to wear out very quickly. It would wear the bearings out in about 3-4 weeks. I changed it out, and now the bearings have lasted probably 4 months and aren't even getting any play in them yet. Like I said though, the 450 could be different, but I'd imagine it has a fairly similar setup. Hopefully I was of some assistance. Later

i may check into both of those ideas tomorrow..i took the wheels off,the shocks off and moved everything around and couldnt find anything else to be the problem...i will look into those ideas tomorrow when i get up and moving around....

i just replaced both my front wheel bearings like 3-4 weeks ago and i noticed on our ride sunday that it seemed like something was popping in the front end...well i finally got around to checking it out and it seems like the left front bearing is gone again....am i correct or is there something else in that area that could make it feel bad....this pisses me off to have it go out that quick....i am not that rough on it...

When you put the new bearings into the knuckle, did it drop right in w/out resistance or did you have to drive it in w/ a bearing driver and hammer? If it fell right in, you need to replace the knuckle. I have replaced about two total but is something I have seen in the shop.

i had to drive the old bearings out of both sides..i cleaned the knuckles up and had to drive the new ones back in..they just didnt fall in...i just dont know why they would go bad after just a short time....i went to the place where i got the Moose bearings from and asked him if i could get that set replaced and he basically told me no..i then proceeded to tell him i will never buy anything from his store again and would tell everyone i knew not to shop there...it might have been childish and done no good but it made me feel better....

Mine are doin' the same thing. I don't know if it is the bearings or what. I
replaced mine about 2 months ago & somethin' just ain't right. It may be a
bushing or somethin' else. Surely the bearings wouldn't go out that fast?

thats what im saying railroader...but mine definitely seems like the bearing again...i may get some new ball joints and see if that helps it any...let me know how yours turns out....

Make sure the ball joints are ok as well.

thats my next step...i have never replaced any will i be able to notice if it is bad???

If the ball joints are bad you should see the whole knuckle move instead of just the hub. sometimes they will squeek real bad also.

ok...i will look into it later this week....

bearings

my bearings are doing the same thing, but mine wore out in 2 rides! the first set lasted 1800 miles and the second set lasts 75 miles that sucks, i am going to get the highlifter sealed bearing kit and see if it is just mud and water, i dont see how the people with disc brakes get bearing problems that is why im really thinkin about getting it (it cant hold water)

i finally broke down and bought the disc brake kit...i will see if the bearings last longer now...
