Steering Knuckle Insert

The splines make it alot harder to press into the knuckle but it's the only replacement I could find. Since pressing the old one out of the control arm and took way too much pressure and shot out like a bullet I didn't want to keep having to do this time consuming process so I bought 3 more of these to replace all of them. Ended up sanding down the splines so I don't have to battle with the rest of this job. Also the splines dig into the steering knuckle ball joint sleeve opening causing damage to the oe knuckle and possibly making future repairs difficult.
