I just replaced mine a few weeks ago, and those look perfectly normal. One of them is just in a different position than the other. You can move them around. I also would encourage you to ADD grease to the inside of the joint boots prior to installing. But be really CAREFUL not to cut the boot when you are removing the boot clamp ring to get in there. My truck rode better after replacement and the old ones were definitely rusty and worn out after about 45k miles. Another thing is to get the correct ball joint separator. I used one that was oriented vertically, and it required me to disconnect an extra bolt. If you get the one that goes in horizontally from the outside inwards, then you won't have to do that extra step.
PM me if you need any other tips.
