@Doubeleive is leading you in the right direction. I think it’s normal wearing iirc you’re lowered on spindles which doesn’t change geometry so there shouldn’t be any wear from lowering per se. Just check for play in components or if you’re concerned and depending on mileage you could opt to just do everything. That’s what I did but I tend to over do things. I just figured at 150 k I didn’t want to mess with doing it piecemeal so I did all the steering and suspension all at once. I used Moog’s Problem Solver line on almost everything except the Pitman arm because I heard about problems with the Moog and went with AC Delco Professional on it. I did all the tie rods, upper control arms, lower ball joints, pitman arm, idler arm and bracket. Not saying you need to but I would consider it depending on your mileage like I said, and taking into consideration your budget and whether anything has been previously replaced.
