    Comments about National Oil Seal:

    THIS WAS a project to install because of where it is located in the shift housing. go on this site:[@] click on axle tech. this was a big help. but slip the threaded rod through a scrap of 2x6 wood , washer and nut at the steering knuckle , and tighten into place. i put grease on the metal part so it would slide in straight. also replace the other side while your at it, as you'll have to take all this apart again to do the driver side.

    Comments about National Oil Seal:

    This seal was a quarter inch too small for my 1986 jeep grand wagoneer Dana 44. I found this to be the case at every autoparts store in the area though. I just part number 2300 instead which worked well. Advance returned my money no problem.

        Since this seal can work on multiple vehicles, please provide the year, make, model and engine size of the vehicle you want to use this on and what exact seal you are looking for.
