So im getting ready to crank my coils on my procomp stage II lift and step up to a 37-13.50-18 Mud Grap. My current setup are 35-12.50-18 KM2's on moto metal 951b with 4.53 backspacing. I am also going to grab a pair of Camburg upper A arms, as my ball joints are shot. My question is am i going to rub anywhere? and will the Camburgs work with the lift/tires/wheel setup that i have
Thanks
Trucks a 04 FX4

 

The Camburg arm is Stock length, but with a uniball, so if your pro comp kit didnt extend your arms, you will be fine. Saem clerence and everyhting, just more travel with the uni-*****. and no more Ball joint troubles

 

They are well worth it. I have a 6" lift and 35" KM2 tires, and my rims have 5.4" of backspacing and I have no problems with the Camburgs. They improve the ride by reducing bump steer from the heavy tires.

 

So you are saying they have more caster?

I talked to them on the phone last month and they said they are pretty much the same as stock. Camburg said they can custom fab a set to adjust the caster if I wanted too for another 3-4 bucks.

 

Not sure about the caster specifics...Maybe its because my stockers were shot and the Camburgs are much larger/beefier and still stiff from being somewhat new...but I sure noticed a distinct reduction in bump steer. Others with the Camburgs (FX4Life) have noticed the same.

 

The reduction in bump steer is from a more solid joint. A worn out ball joint is going to allow the knuckle to move more when you hit bumps, especially with bigger tires and longer knuckles.

 

kind of true, yes the more solid feeling of the truck going over bumps is the solid uniball, but thats not bump steer, bump steer is when your toe changes throughout the suspension travel, therefore bump steer will cause your toe to go out of alignment when the suspension travels which will cause it to feel unstable

 

Once you crank it up you shouldnt have too much rubbing but it will deffinately happen from time to time depending on the incline or decline that you are on. I just put 37's on with the same backspacing with the pro comp and bilsteins up front and I clear fine for day to day, Ill rub occasionally but nothing serious, Im gonna trim it up here in the next week to make sure I dont have any issues on the beach.

Mud grapplers are sweet tires, i ran them for a long time, the noise is pretty feirce but they are very mean looking and amazing in the mud. I just put the Toyo M/Ts on now and I love them but cant say anything too bad about the Nittos except the noise since I ran them for at least 50,000 miles!

 

If there is play in the upper ball joint, it can change the toe when you hit a bump, for what it's worth. If the lower ball joint and tie rod ends are tight, and the upper part of the knuckle moves in/out due to the worn out upper, it will change the toe a bit.

 

Yup, and guess what? One of my tires is cupped from my old worn ball joints doing exactly that. They are re-aligned now, but the bad tire is ridiculously loud and its kind of embarrassing.

 

Throw the tire on the rear axle and do lots of burnouts. lol
Seriously though, swap it out back and drive aggressively for a while, it will help straighten it back out.

 

Its on the back right corner, still loud as can be. Driving aggressively isn't my style though and with 105k miles I doubt the limited slip clutch packs would enjoy it.

I'll see though, these tires were wearing perfectly up until this incident. Already 25k miles on them and EASILY enough tread left to go at least another 25-30k.

 

WOW!!!! I thought I was the only one with bump steer. I had the procomp stage 1 kit, then upgraded to some Icon coilovers. And the tires don't just chirp; on some of the big bumps, it sounds like I'm skidding! It is seven years old with the stock ball joints. Would this solve that problem? Even when I hit a large bump such as a long speedbumb, the tires squeal even if it doesn't steer.
