I have a 2004 Lincoln Navigator I put a 3” leveling kit on it with some raptor svt wheels and 35” tires and I’ve been getting a lot of rattling noise over bumps at slow speeds just replaced the wheels bearings on both front wheels last month. Looks like it might be the upper ball joints they sit at a funny angle and seems like it’s putting a lot of pressure on them. And I tightened the **** out of it but there’s still a small gap in the ball joint. I heard leveling kits are not the best hahaha but Im about to have my second kid so I don’t want to put an expensive lift kit on it. But I don’t like the look of these things stock.

so I’m trying to find an extended upper control arm to fit it does anyone know if an f150 one will work? I can’t find one for the navigator of course haha

I’m so tired of this rattle!!! it’s only when I hit pot holes and other small bumps in the road. I thought I fixed it it when I did the wheel bearings. But it’s still there. I’m not even sure if it’s that ball joint making the rattle noise I’ve quadruple checked every bolt on each side and I can’t find anything loose. I’ve jacked up the car on several occasions and used a big pry bar and a jack handle to shake everything but it only makes the noise while driving. I put the jack handle under the tire and shook it up and down no noise!!! It’s so frustrating I don’t know what else to check I’m about to jump this thing until the rattling part hopefully breaks But my luck something else will break and not even the rattling part

ANY info or help is much appreciated thank you

 

I see no reason the F150 extended knuckles would not fit your navigator but I have no personal experience on this exact issue to back up my statement.
