It's probably the swingarm bearings. When mine wore out it made creaking and cracking sounds.

 

how much did that run you to replace?

 

The pivot works kit was about $50-60, and I installed it myself. If you're getting a shop to do it for you, expect to pay 2-3 hours of labor on top of the cost of the kit. The sooner you get them replaced the easier it will be. Mine were bad when I bought it, and I had about 25 hours of riding on the bad ones before I figured out that they were bad and replaced them. This made it difficult, because there was barely anything left that resembled a bearing when I got it apart, and had to spend a few hours extracting the bits and pieces of the old bearings.

And if you do the installation yourself use lots and lots and lots of grease.

 

first try proping the rear end up on something too get the back wheels off the ground, grab the rear axel with both hands and shake it foward and back. If u get some movement u need axel carrier bearings. Also check to see if your axel carrier bolts are all tight, they can sometimes wiggle themselves loose and it makes that kind of noise

 

alright it wiggles just alittle bit. but i didnt check the bolts yet. ill have to do that tomorrow when i get home.

i called the dealership and the guy said it is probally the axle bearings so if tightening the bolts doesnt fix that i guess im gonna have to go get new bearings.

 

it should move very little to no movemnet at all
