    Pinion Seal

    Whose done it? I just did mine and when I put everything back together I found a washer that possibly goes between the yoke and the nut that holds the yoke. I don't remember taking that washer off but maybe it stayed stuck to the yoke and when I put the yoke down then it came off. I put everything back together and found that washer laying there, now I'm not sure if it belonged to my car though cause I did the work at school and there is always pieces like that laying around... I kept the washer anyways though just in case. So I need someone that has done this before to see if you guys remember a washer being between the yoke and the nut that holds the yoke...

    I could go check my manual, but as far as I know... there should be a washer. What was your procedure for tightening the pinion nut?

    I think there is one too but ahhh what a pain to take it apart again... I used a impact to tighten it ops: you think I could've damaged the bearing?



    Moral of the story, don't let other people help you

    There is definitely a washer between the nut and yoke. Tightening with an impact is fine if done correctly.

    Did you punch mark the pinion shaft and pinion nut before removal and measure your turning torque before and after replacing the seal??

    You may have overtightened the pinion nut, which means you would need to replace the crush sleeve with a new one.
