JLAWS

Has anyone ever changed their rear sway bar links? Appears to be very easy to do. When I reach in behind the rear wheel and wiggle them left to right they seem pretty loose compared to the front which I can barely move. I don't hear any noises in the rear when driving. They look fine, I am just wondering if there is suppose to be so much play in them. Might be time to switch them out after 10 yrs. Wondering if my handling might improve with new ones.
Can someone check theirs for me? They are not cheap at around $45 a piece

Thanks in advance
