Moog ball joint.

I just bought moog ball joints and I have yet to put them in. I have a question as far as the lower ball joints. They come with zerk fittings directly in the center. The zerk is 90° but they did not come with a cap. To me it looks as if the axle will hit the zerk fitting while rotating. Has anyone had this issue. I am putting them in after work so I am not certain that they will hit. It just looks really close. Thank you all.

I had a zerk fitting on mine and i just put it forward and inwards and it clears fine.

I just installed a tie rod end(at the pitman arm) by moog and so far so good I am also about to install new tie rod ends on the tie rod by them and the quality looks like they will be ok for what they are till I can afford some better CROWN ball joints and ends
