​The stock rubber bushings wear out very quickly and leave the upper end of the dogbone very sloppy.  The bushing is modified to fit tightly inside the upper dogbone hole.  A lot of times, you'll need to cut the bolt to get the original bushings out, so new high grade hardware is included in the kit.  Two tubes of grease are included.  One is more than enough for the installation.  The second is in case they start to squeak in the future. ​
