Hello all.

I took my truck to get it aligned and they said I needed to replace the upper ball joints. He also said, if I have the upper arms out to knock out the plugs. I had the arms out several years ago to replace the bushings, but didn't know about these plugs. He said it would make it easier to align, but its been aligned a few times with no complaints from other shops.

In doing some research, I found this tool. OTC 7491C Upper Control Arm Knock-out Tool.

I wanted to find out if this is necessary.
