Re: 4x4 steering issue - won't return to center

Well I did the tighten method a few times, and even replaced all the new ball joints, with more new ball joints. No difference.

Some have said the scrub radius because of my wheels/tires?

Re: 4x4 steering issue - won't return to center

Alright....I bypassed the factory torque specs and torqued to feel. My knuckles turn very freely now. I put everything back together and she is a different truck! Also took out all the shims. She is back to factory setting now. Thanks for all the help to track down this monster.

I was under the impression the knuckles turned freely before. But glad you finally got it figured out and can enjoy driving it now.

Re: 4x4 steering issue - won't return to center

Are you sure your box is not setup wrong? I don't know what redhead is but a quality box like Lares is rebuilt in USA to factory spec. I have one of their boxes in my truck. I've had your problem before and it was the box being setup wrong (Not necessarily setup too tight).

Re: 4x4 steering issue - won't return to center

I have maybe driven this 50 miles since my last post and it seems to be doing the same thing again. Loosening the ball joints even more DID help, but it still won't return to center and is driving like $hit. Weird thing is I swapped out my power steering pump for a new one because it was making some noise, now this new one is starting to whine already! (fluid is fine).

I have not swapped out the u-joints in the front axle shafts, and have not put new bearings in.

RedHead boxes are built back to factory spec. I have actually tried 2 of them (different ratios) to see if there was any difference.

Any "new" ideas?

I had the axle out of the truck when I took it to get gears installed. Center pins are all fine. I have even tried multiple shims to correct the caster....frustrating!

Re: 4x4 steering issue - won't return to center

I will also add that the spindles turn freely when there is no weight on them. I have no idea what they are doing once I set the truck down.

Re: 4x4 steering issue - won't return to center

OK, I'm going to ask a couple questions that I am not positive of the answer here, but it's worth asking.

When the front springs were installed, were they installed the correct direction? Some springs have the center bolt offset to one end of the spring. I don't know what these are from the factory. I also don;t know if the bushings are the same on both ends that would even allow such a thing.

If the differential is now on a different center of the spring, your caster would be affected. Maybe the ideal location for YOUR truck with those wheels, tires, lift is closer to a +1 caster instead of +4 to +6

It may be worth checking.

Also, did you install a new steering damper with it? If so, is the cylinder bad?

What does the book say for the correct caster spec for this truck?

The springs are ok to install either way per Skyjacker. Mine came with the larger bushing sleeve for the front and smaller for the rear for the shackle and that is how they are installed right now.

Factory is 4-6 caster angle. I have tried both 2.5 degree and 4 degree with no change.

I put a damper on it for about 3 days, it has been off ever since. It didn't change anything either.

Re: 4x4 steering issue - won't return to center

How fast of a return are you getting? any at all? The tire is just about 13'' wide, and how centered is the tire over the center of the wheel bearings?

Hardly any return. You turn, it stays. I am constantly "wheeling" this thing while driving. My driver side tire maybe sticks out 1.5" and passenger is 1.25" just by taking a rough measurement. I forget how far the wheel bearings are stuck in there but seems like the bearing is right in the center of the tire. Thoughts?
