If you want peace and quiet, buy something sealed, rather than open heim-jointed. None of the good brands are cheap, though. I like the Powergrid's, but Whiteline's are nice, too.

 

And BTW, replacing endlinks is an easy DIY job. It's easiest if you have both wheels off the ground (front or rear - not left or right), so the tension is released from the sway bar.

Rears - Unbolt the bottom side of the link first, and then unbolt the mounting bracket holding the top of the endlink to the chassis. You can then easily unbolt the top of the endlink. Reverse that procedure to reinstall.

Fronts - Just like the front, except you can easily access both sides of the endlinks.
