I changed the swaybar end links on my car and getting an excellent ride after doing so but my thght is i might have tightened thm too tight....is thr a such thing...?? Cuz my mechanic used an impact gun and I'm not a huge fan of thm....i just wonder by over tightening i might have taken away from some of the absorption of impact on the cushions ....Thanks in advance.

Yes, you can definitely overtighten them.

take a look at it, should be marshmellowed slightly but not flatened

There pretty flattened...did i do any damage or can i just unloosen thm...I've had thm on for like a day or two..

Loosen them up and see what happens. I doubt they took a set that fast.

Shouls I go hand torque tightness or a lil gun tightness ...??

Hand torque them. Then inspect them after every 50-100 miles to make sure they are not backing out.
