C Joints???

I posted this picture of my Jeep on Instagram, and someone commented and said my C Joints are bent and need to be reinforced. What on earth does that mean, and what do I do about it???

It's your wheels and how they appear to be kicked out at the bottom. In real life, do your wheels appear to sit vertical to the ground and parallel to each other? I believe the the real issue is your camera and its wide angle lens distortion causing a mild fisheye effect. Its the same reason your stinger looks gigantic and the windshield too small. Most cell phones have a wide angle lens and nearly all point and shoot camera zoom lenses begin at a wide angle. Surprisingly few people understand how cameras and lenses can effect an image.

Here is an extreme example of the lens distortion I am referring to. I wouldn't accuse the streets and buildings of NYC of being that crooked. Its the lens.

I don't know how anyone could possibly tell your inner Cs are bent from that picture. Oversized tires exaggerate the look of camber so it's not uncommon for people to think something is bent simply because the tires look slightly tilted. The only real way to know is get it on an alignment rack.

maybe they were eluding to the color and some sort of deragitory insinuation.

If your front tires are wearing evenly you have nothing to worry about.

I'm fairly certain without actually knowing that you have larger than stock tires. Larger tires weigh more...and "hang" - They are suggesting that you replace your balljoints with offset balljoints to distribute the weight better.

Its the camera, you cannot be sure that its bent unless with measurements. In some cases a bent axle can be seen, but one cant make that big of a assumption off a picture. Pictures can be distorted.

The front-end of a TJ can often fool the eye into thinking the camber angle is off, making the wheels look like they are canted in at the top. It has fooled me into thinking the same thing on my present TJ.

I would however get your toe-in setting checked, it looks like there may be insufficient toe-in. It actually looks like there may be a little toe-out which if so, needs to be corrected to prevent irreversible tire damage. Though this too could be an optical illusion... though I'd definitely get the toe-in checked.

Looks like the wheels are turned slightly to passenger, which may contribute a bit to the "toe out" effect.

Very true, the front end is really tricky on the eyes.

When I was doing my own alignment on my new HPD30, I got my tires perfectly aligned. However when looking at the assembly, it looked like it was out of alignment. After quadruple checking all measurments I finally concluded that my eyes are playing a trick on me. It bugged me that my measurments were saying one thing and my eyes were saying another. It is most likely the case here, however there is the added camera distortion that will probably worsen the effect thus tricking our even eyes more.

The grass and trees dont look distorted enough to me, but I dont rule out the camera issue either, thought id provide her with more info. Seemed like it was something she could learn whether it applies to hers or not. I see a hefty number of lifted jeeps that only have lifts and not some other wise mods that would remedy the effects of the lift.
