Ok. These three replies seem appropriate.
In summary: The Ford Factory upper control arms have a permanent upper control arm ball joint. That ball joint is not replaceable. Correct?
Based on this assumption / information, ones' first repair of defective upper ball joints should be not with the Ford / Motorcraft replacement upper control arm parts but with the "better" MOOG Brand upper control arms. These have serviceable ball joints with grease nipples. IE: Latter, the ball joints on these arms can be pressed out and replaced with a equal quality MOOG ball joint the second or third time a guy needs to rebuild.
Is this Correct?
Thanks for your valuable assiatance and expertise.
My '99 Ranger (at 65,000 mi.) is starting to make a lot of noise up there and the rubber boots are cracked open. I intend to do a rebuild in the spring, right before I have new tires mounted. That way, I think I can save an alignment, get every mile out of the old tires, and have all new critical suspension parts up front for the alignment.
Does anyone have any good pictures of new MOOG Parts to post?
