How easy should a bearing sleeve rotate with fresh bearings?

Sorry for the newby question but I have searched and searched and have not really found an answer.
I recently acquired a 2003 KDX for cheap and once I got it home realized there was something a miss with the rear end. After taking it apart I found that pretty much all the bearings were shot. After lots of PB blaster and patience I have gotten the old bearings out some fresh ones in.
My question is once I got the seals and sleeves on the unitrack the sleeve does not rotate easily, it rotates but I have to muscle it pretty good.
Any ideas of where I might have gone wrong?

Thanks

Haven't had that problem myself. You have to be careful when installing those needle bearings not to deform the end lips of the outer race. I like to use a 2 diameter driver with a pilot the same OD as the inner race bushing. If installed with uneven force, you could deform the lips and cause the needles to bind up.

seals add a fair amount of resistance.Try removing them then rotating the sleeve.
