There was an issue before the 05+, I'm not sure if it had something to do with the axle upgrade for the coil suspension but , I agree. My 03 lost ball joints very quickly. My current 07 has 400K and had one set of MC replacements and they are still good.If Motorcraft is so good, shouldn't they have lasted more than the 99,300 miles? They are not just a little bad!
No difference. Ball joint wear is affected by the weight on the axle, tire size & wheel offset, vertical distance between the upper & lower, and driving conditions; not suspension type.Mine is leaf spring not independent. That configuration should be easier on the ball joints, no?
The one that gives you the best price the day you check, on genuine correct parts shipped. Check them all: Amazon, eBay, RockAuto, FordPartsGiant...What's the best online source for Motorcraft ?
A good choice. That's what was in the axle at the factory, as Ford buys them from Dana.Dana/Spicer.
I don't believe that's correct. If you're talking about the camber adjustment sleeve, if it "floated" it wouldn't do it's job of maintaining the camber alignment.Not really. The upper has a sleeve that floats in the axle ear. It has no positive stop, so the sleeve will always slide to its rest position after a few heat cycles & some road vibration. Yeah, cranking down on the upper nut will cause the tapers to spread the sleeve, and that will produce some friction. But it's still gonna slide after a mile or 2.
Then what do you think stops it? Look at the one under your truck - the lip on the camber cam doesn't touch the surface of the axle ear, so what's holding the cam at that location?I would find it hard to believe that it could move up and down.
