Comments about National Oil Seal:

don't go by the web site. if you need two, go to autozone. there you will get exactly what you want. web site showed qty. 2, so that's what i ordered. only recieved one. when i contacted them through 800 nubmer, they explained that web site is a little confussing, the qty 2 ment you need 2 for the job, not that your ordering 2. what kind of bs is that. 2 means 2!!!

  • Q:

    I'm only replacing one half shaft. Why do I need 2 seals.
    Asked on 1/5/2015 by jr from Tampa, FL

      I'm happy to help, JR! The details found under the Product Application(s) heading indicating that 2 are required means that your vehicle uses two of these seals. Since you are only replacing one cv axle on your 1997 Ford Taurus GL, you will only require one seal.

  • Q:

    is this seal for the half shafts or the torque converter?

      I'm glad to assist you! This is a auto transmission output shaft seal.

      Answered on 7/30/2014 by Vincent from AAP


      I'd be happy to help you with that! It is the output shaft seal. Since you have a front wheel drive vehicle it goes where the axles insert into the transaxle [transmission] which some refer to as the axle seals.
