How the hell does one deal with 0 caster?

I dealt with it by installing offset ball joints to gain 3 1/2*.

You actually did it .... Wow. Did you post a follow up ?

Just that I had done it and that the uppers are grease-able and seemed stout. The lowers are not grease-able and don't seem like anything special, but I will eventually drill them and add grease fittings. So far they are holding up fine and my shit goes where i point it. Now if I can just figure out where the ******* intermittent shimmy is coming from......

Bump steer is caused by ONE thing.

Messing with all of that other crap won't help you one little bit in regards to bump steer.

Define the problem. Determine why that problem is occurring. Address the root cause. It's that simple.

If bump steer is truly your problem, it's being caused by the drag link and track bars traveling differing arcs.

So what you're saying is when my ball joints were worn out and I'd hit a bump causing my Jeep to steer into another lane without me asking it to or when all the grease blew out of my tie rod ends and I hit a bump and my Jeep steered my off the road and tried to kill me that wasn't bump steer either. It was just going over a bump and my Jeep steering itself, but not bump steer. OK, got it.

Bump steer has a very explicit definition in this application. You weren't experiencing bump steer, you were experiencing the results of crappy steering components.

So if the symptom was the same as misaligned draglink and trackbar, how would you describe it?

 

[ASSFROW]

I've already told you how I would describe it. I care about the cause, not the symptoms.....focusing on the symptoms alone can create muddy water and can make finding the root cause pretty difficult. Diagnosing the problem in a methodical, sensible fashion will almost always expose the cause very quickly and with little wasted time.

Determine the cause--are the drag link and track bar mounting points parallel, in the same plane, and very close to the same length or not? If not, it's bump steer. If so, move on and find the cause elsewhere, it's not bump steer. On that note, I've never felt worn out steering components (even terribly worn) give a remotely similar feel to bump steer.

I get paid to do this stuff and that's how I go about it. You can call it whatever you like and go about diagnosing the problems however you like. Judging by the pictures and the OP's posts, I think he's mistaking his problem for being bump steer when that's not the case.

Well if someone tells me they have bump steer I'm not going to be arrogant enough to tell them it can only be specifically caused by one thing. I'm going to understand that they are describing what happens when they hit a bump and start the diagnosis from there. If someone tells you when they hit a bump their JK changes lanes, how would you describe it?

 

[ASSFROW]

It could be a multitude of things. E-diagnosis is pretty tough, especially when it comes to front end issues. I would first perform a dry steer test to check all linkage ends. Then check all control arm bushings by loading them using tire rotating with the Jeep in gear.

It has nothing to do with arrogance and if you truly think that, you've got a ways to go when it comes to giving technical advie. There's a method to how I was approaching his issue and getting to eventual answers is intentional. Again, I'll do things my way and you can do things yours.

If I took it wrong I'm sorry, but even the above statement comes across arrogant.

As for the 1st part I completely agree.

You said you watched Planman's videos, did you do all of the tests?

Like everyone has said it's hard to diagnose over the interweb. The factory ball joints and factory tie rod ends are weak links, but if your lift has been on for 2 years and you haven't tightened everything or serviced the control arm joints it could be lots of things. I wouldn't rule out a worn steering box either, but starting with Plamnan's video, Impeds suggestion for the control arms you can rule out or fix the cheapest/easiest stuff to fix 1st.

what brand for the offset ball joints?

Raybestos Pro. If I were doing it again I think I might do the adjustable upper (2*) and Synergy lower. I'm happy about the extra 1 1/2 degrees the lowers gave, but I'm not sure how the lowers will hold up. They are defo an upgrade from stock, but I don't know how much. They've been installed for about 6 or 7 months and a few wheeling trips with no issues. The only odd thing is the steering stops don't contact where they are supposed to. I guess I should take some pics and do a short right up. I didn't, because so many people poopoo'd the idea.

I bought them from Amazon. They had the best deal at the time.

 

[ASSFROW]

A little but should hold still if held. Bumpsteer from my experience the wheel jerks and takes your hand with it.

Unless your track bar and drag link are parallel and traveling in the same arc, then it's not bumpsteer. :nono-1:

:shitstorm:

 

[ASSFROW]

Fixed it for you.

Thanks.

So is it possible that worn out track bar or drag link bushing/end/etc could cause the DL and TB to travel in different arcs, resulting in bump steer?
