Camber kit and transmission question.......

i had somebody come today to look at my jeep to possibly buy it from me. they said everything was fine but had an issue with the car diving into turns and the transmission being a little noisy in 4L. i think the cornering might have to do with the camber and alignment. i have some negative camber on the fronts due to my lift......3.5" lift. how much do camber kits run and how hard is the install? and also is the noise coming from the transmission normal in 4L? i'd hate to not be able to sell it because of a camber kit....

thanks,
chris

well where was the truck when in 4l? On the street? Dirt? 4L will whine a little. The sound is not coming from the transmission but the tcase. It is normal. On the turns, was he thinking it was going to corner like a road race car? It is a flying brick, it will take a little effort to drive as you know. I think the guy was just trying to find ecusses.

it was in 4L on the street and i figured the whine was normal.......but thanks for the clarification. his brother also has a jeep with 31's i believe but hasn't lifted it yet. i mentioned that the diving into turns and wind blowing it all over the place was normal once a jeep is lifted.

any ideas on the camber question?

thanks again,
chris

DON'T Drive in 4L on the road. There is too much stress on the driveline and axles in curves in 4L.

In 4L the t-case is whining a bit. The faster you go the louder..
In curves on the road in 4H or 4L the steering will handle a bit weird. When you corner sharply that will become more weird.
Try it in 2H, then everything should be ok.

You should use 4H and 4L only on slippy ground.

Your camber is the same as stock. it's got a live front axle still right? camber doesn't change when lifting a jeep. only toe in and caster angles.

i'm not sure what you mean by a live front axle. maybe i'm not explaining it correctly or using the right words.......when you look at the jeep from the front, the bottom of the front wheels are angled outwards. kinda like this: / \

thanks,
chris

p.s.-if needed, could a camber kit be done yourself?

if you have the NV3550 transmission; they are a little noisy by default.. Mine used to sound like marbles rolling around in a tin can; but a little Royal Purple synchromax quieted her up significantly.

Camber is only adjustable if you install adjustable ball joints but without the right tools, that's a tough job. A "live" front axle just means the axle is solid all the way from side to side, unlike a vehicle with an independent front suspension.

You can see that the "live" axle housing below is solid all the way across. The below pic is actually a rear Dana 44 axle but your front Dana 30 has a similar live solid axle design that just adds knuckles to make it steerable.



The wheels are connected to the axle in such a way that the entire axle moves up/down/or lifts on one side and droops on the other on uneven terrain.

IFS or Independent front suspension axles (non live) mount the center of the axle rigidly to the frame and the wheels can move up-down independently of the axle. This kind of axle is more popular with cars because it offers a better on-road ride, but a solid "live" axle works better offroad. The Jeep community went into mass hysteria years ago when it was rumored the Wrangler was getting an IFS front-end.

And yes, your / \ indicates a camber issue, not a caster issue.

Possibly worn ball joints or a bent axle tube.

If your tires are sitting like that on the front axle then you have something bent in that front end. Like axle tubes or knuckles.

The diving he is feeling is going to come from the 3.5" lift springs in there with stock arms. I'm assuming your sway bar is still hooked up in the front so we can rule that out. This is perfectly normal for a lifted Wrangler.

However that tire situation is not. There is no "Camber kit" for a solid axle Wrangler. Take a pic of how it's sitting and post it for us. That will help a lot.

Thanks for all the feedback. I'll see if I can get a pic and post it for you guys to look at.
