Blaster Rear Wheel Bearings? How do you fit them?

ok thanks for that info,
so how do you change carrier bearings?
i have play in the rear wheels, up and down movement, aswell as side to side movement
 
easy enough, take your back wheels of ,then loosen your lug nuts(the two big bolts on the axel) then your back sprocket and lrft hub slide the axel out and opo the old bearings out ,then put your new ones in and put it all back together
 
Any thing we should be looking for on the axle or carrier it's self, i noticed last night when checking my wheels that my axle has up and down movement, not so much on the side to side tho . One of the reasons i was checking it, is on hard accelleration sometimes the bike lunges to the left hard
