Samsung shock absorber free play ?

Hi, is it normal for Samsung shock absorbers to have some free play ? mine have up to 1/2" travel with no damping and the drum is shaking like crazy when upto full spin speed.

Part # DC66-00650D 80N & DC66-00650C 80N

If it's not those then it could be the spider :(

Thanks
