Hello,

The lower ball joints on my 00 Navigator 4x4 are worn out. I picked up some replacments at my local parts store, got back home, looked all over for a service manual found one only to read:
Is this accurate? If they can be replaced, is there some documentation you can recomend online?

Thanks for the help!

How to change lower ball joints 2002 Lincoln Navigator?

Ball Joint Replacement:


I used the rental tool to press out the old ball joint and press in the new one. When pressing out the old ball joint the key is to properly set up the press, tighten the screw on the press, then give the screw a few good solid blows to shock the old ball joint. Once I did this the old ball joint pressed out almost effortlessly. Installation of the new ball joint was a breeze. The only comment is be extremely careful not to damage the axle boot seals. Have wire on hand to tie the spindle assembly and axle for support to prevent damage to the brake hoses and ABS system.
