steering problems

I have upgraded all of the steering, Rusty's Jeep XJ-TJ-YJ Tie Rod Conversion. I have put new steering pump and steering gear box on the XJ. The front end is aligned and, the tires are balanced. I have put a Rusty's XJ Cherokee Long Arm Upgrade on the Jeep. Drag link is where it is supposed to be. I have replaced all bushing on the Jeep with Daystars super kit bushing. When I go down the road all it wants to do is wander back and forth. If, from a stop, I step on the gas the jeep wants to go to the left and, if I hit the brakes hard it wants to go to the right or left. What is making it do this? It is getting hard to keep it right now. HELP!!

Re: steering problems

What are your alignment settings? It sounds like either the caster is off or you have something loose in the steering. Have someone shake the steering wheel while you look at everything in the front steering/suspension.

Re: steering problems

What way is it pulling when braking, sounds like you could have a caliper sticking, do you replace the brake lines?

Re: steering problems

This is a common symptom of mis-matched geometry between the track bar and drag link. Would you mind snapping a pic of the front end?

The angles of both should be as parallel as possible, when drawing a straight line from mounting point to mounting point. If those are all good, then as stated, it may be an alignment or brake issue. Although, the brake issue would be less likely to cause noticeable pull under acceleration.

Re: steering problems

I will have a picture for you tomorrow. I don't think it's the brakes that are causing this problem. I can be going down the road fine and it will start to wander left and right. Wife is scared to drive it now.

Re: steering problems

Mine did that same thing. The caster was off.

This article describes how to check and adjust the caster:

A couple spacers made all the difference.

Re: steering problems

Caster could be off, should check the specs on your alignment paperwork. They might have only set the toe and straightened the steering wheel, and not set the castor because of the lift. Castor should be 5-7*, but you can get away with 3* if everything else is real good. Castor gives a little resistance to turning (just a little) and so causes the steering wheel to come back to center, not enough castor eliminates a "feel of center" and so the vehicle tends to wander.

The darting left and right sounds like possible bump steer from the drag link and track bar not lined up well enough.

Re: steering problems

cRusty's is known for sending a drop pitman arm and no drop track bar bracket. Did you replace both of these parts with your new steering and lift parts?

Re: steering problems

pitman arm has been replaced. The problem could be the caster and I think that is going to be the next thing to be checked and or reset. Sorry I don't have pic, today went bad quickly, I will have one tomorrow.

Re: steering problems

Drop pittman arms typically mess up your angles creating bump steer issues. A front end pic will easily show if you have a problem by throwing it in paint.....make sure the pic shows both mounting points for the track bar and drag link in one pic.

Heres a pic of mine with no drop pittman...drag link and track bar almost parallel..




Heres one with a drop creating bumpsteer from them being un parallel...

Re: steering problems




Looks like you might have some slight bump steer issues as you are a bit out of parallel. This causes the steering to pull one way when the suspension is compressed, and the opposite way when the suspension is extended.

So, this could cause the pull one way when accelerating and the opposite when braking.

I would advice fixing this, then looking at the caster if you still have a problem. IMO your drop pitman arm is causing the issue. A stock pitman arm would fix it. So would raising the axle side track-bar mount.

Re: steering problems

The inverted T style steering that is UTK will cause some roll on the tie rod which you can most likely feel. Inverted T needs the drag link to be more level to not feel tie rod roll as a dead spot. The drag link track bar are off a little, don't know how much of that you'd feel, depends on how sensitive you are. The mongo SJ drop pitman arm helps the drag link angle, but it puts the angle on the drag link out of line with the track bar. Pick your poison.

Not trying to be harsh here. UTK inverted T is the worst choice for XJ steering. It has a dead spot and the ground clearance is worse than stock.
