I'm going to replace my original U joints on my 07 Tahoe next week with Moog brand, with the grease zerk in the trunnion cap.Are these type ok or are the ones with the zerk in the body better? I have done quite a few on my previous cars and trucks but never any with the zerk in the trunnion cap. I would think there might be a vibration problem but I guess there isn't.Thanks.
