Ford--premature ball joint failure
Posted: Sat Jan 14, 2006 12:12 pm
Well, you can tell it's cold outside, this is my 2nd post of the morning!
Ford has had a history of ball joint failures, long before they should occur. I had to replace both upper and lower joints at 76,000 miles, they were real bad especially the lower ones. There have been cases of the front end collapsing, when the wear gets so bad the socket comes apart.
The root of the problem is the lack of grease fittings in the original factory installed units. Note the "E-450 lubrication pionts" diagram, in Bill Hemme's Jan, 1st post. Notice there are no grease fittings on the four ball joints. Demand your replacement units have fittings.
To test for wear, jack wheel slightly off the ground, making sure jack is inboard of where ball joints support wheel spindle. Then place a bar under the tire and lift up, have someone watch movement of lower ball joint while you are doing it. Or better yet remove tire and try to move spindle up and down
Other than the life safty issue, bad ball joints impact the front end alignment. Estimated cost for replacing all four ----I paid $460 (One needs a special puller) George B
