TJ not returning to center after turn

97tjMike - 25 Aug 2007 16:51 GMT I have a 1997 TJ Sport with power steering. I posted this question a while ago but never really got an answer. The problem is that the steering wheel does not *completely* return to center after a turn. It attempts to, but never completely bounces back. Also, when driving straight down the road, the steering wheel does not "bounce back" to center if it is turned or flicked a little bit. It's kind've like something is binding. I asked a mechanic and he suggested checking the U-Joints, which I did and they are both OK. I suggested an alignment due to a bad castor angler but he said the castor cannot go off enought to do what it's doing. The dealer I called also said an alignment wouldn't fix the problem, and it was probably a worn out part. Here's what I know:
Recent new Steering Box (problem happened before and after replacement) Good Front U-Joints (not binding up anyways) New sway bars (don't think that's related but I'll put it up here anyways) Recent lube of all zerk fittings when I did my oil change a few months ago.
I haven't had it aligned since I bought it, however I have put a 2 inch spacer coil lift on it and when I did that I did a self- adjustment of the toe-in and the steering wheel centering.
Mike Romain - 25 Aug 2007 17:12 GMT I had a grabbing and not returning issue on my CJ7 a bit ago. I checked the steering shock first and found out it wasn't a shock, only a rod in an empty tube so that wasn't the cause.
I then found a lower ball joint bad during a grease job when I noticed the torn boot. Replaced that and all is well again.
You can sometimes pick off a bad ball joint by looking at the tires or using a level even. If one tire seems to sit out at the top or bottom a bit more than the other side, suspect a bad ball joint. You need a 'big' pry bar to get movement in them with the solid axle setup.
Sometimes if you are a big person, you can grab the top of the tire and rock it in and out hard enough to get the Jeep just a bouncing, you might feel a click or thunk or shift as the joint flexes.
On a TJ, you also might want to check the track bar bushings. If worn, they can cause it to 'hang' before centering too.

Hmm, I think I possibally may have found the problem. I do remember when I last lubed the chassis, the lower ball joint on the drives side had a rip in the boot. I wonder if this is it.

I wonder if this is it. My only concern is that I had it inspected last month by the dealer, and wouldn't a ball joint be grounds for failure in NY?

It probably is grounds for failure, but how do you know the dealer properly inspected everything? So many dealers are scam artists and just plain sloppy in their work. If in fact your ball joint is defective, I would suggest finding a new dealer or checking things like that yourself. It is actually pretty easy to do, and that way you're not putting your life in the hands of someone who might not value your safety as much as you do.

Yes, but, the measure of ball joints is in the movement of the joint. It also makes a difference if it is a loaded or unloaded ball joint on how it is checked. Finally, the strength of a man isn't always enough force to make the failure apparent, as opposed to the weight of the vehicle and force of driving on the joint. Failed ball joints can be full of rust and dirt if the boot is torn, and therefore show no movement, but still stick. No other way to gauge without a crystal ball. Tearing of the boot is enough to suggest replacement.
It is hard to diagnose, but the symptoms usually speak for themselves. Spdloader

Well, they don't get the name $tealership for nothing....
They 'are' hard to spot though....
If the boot is torn, suspect joint movement as the cause.

Mike Romain - 26 Aug 2007 14:45 GMT > so no really easy way to test it though other than replacement? I looked carefully at the gap on each side and noticed a difference. I also used a large pry bar and got a slight bit of sideways (front to back I think it was) motion so I changed it. I was lucky and that was my trouble.
A carpenters level put on the rim to check vertical angles can sometimes pick off a slight difference between the sides indicating the blown joint.
If you have 'not' been bushwhacking lately, then the only way to get a torn boot is from joint movement.

[quoted text clipped - 8 lines] > > so no really easy way to test it though other than replacement? Take the weight off and attempt to move the tire up & down, and in & out at the top and bottom. The tires should not move along these axii, if they do, then ball joints move up on the list of usual suspects for your steering trouble.
Mike suggested that if the boots are torn, the joints are worn. The flip side of that rule is that if the boots are not torn, odds favor the joints being in serviceable condition.

Have the caster checked. That is many times the cause of the symptom you are describing. It is possible you were on the low limit of caster before, and the lift would just make it worse. Having it checked is much cheaper than replacing parts and hoping you find the problem.

Spdloader - 25 Aug 2007 20:33 GMT That is a symptom of one or more bad ball joints.

Jeff Strickland - 25 Aug 2007 22:21 GMT You are describing the classic symptom of improper Caster Angle.
Draw an imaginary line from the lower to the upper ball joints that passes through the center of the spindle. This line must favor leaning toward the back of the vehicle, I _think_ this is called "negative caster," but I'm not entirely certain of the term.
This problem typically come after adding a lift kit.

Also, I would bet that the angle spec you gave him is not correct because of the negative value. Maybe that is the camber spec?
If I'm not mistaken, most 4x4 vehicles have several degrees of caster.

Jeff Strickland - 26 Aug 2007 01:38 GMT Sorry, I just pulled numbers from my a.s for the sake of illustration. The numberw were not intended to be anywhere near right, I only wanted to show that the desired setting was the one further from zero as opposed to the setting that was near to zero.

Jeff Strickland - 25 Aug 2007 22:37 GMT I wasn't very clear earlier.
When you have sufficient negative caster, the weight of the vehicle settles into the steering geometry and literally forces the front tires to be straight ahead. If you've ever ridden a chopper, you probably noticed that the steering was very heavy to get off of center, this is because of the very steep Caster Angle that is a natural part of a chopper. Choppers go straight very easily, but it can be a chore to make them turn.
When your Jeep has sufficient Caster Angle, the tires will prefer to be pointed straight ahead. If your Caster angle is almost right, you might notice that the wheel will spin almost by itself from a full lock turn back to center, or within about a 1/4 to 1/8th turn from center. It is not unusual that the steering will have a bit of slop on either side of center where you have to provide the input, but outside of the slop range, the wheel should return to the slop range pretty much by itself. The test I like is to mimic backing out of a parking space and turning the wheel nearly full lock -- the wheel should move towards the center when you go forward, and should require little more than a flick of the wrist if it needs that much. A U-turn should be self-centering too.
I think you need to visit an alignment shop to have the caster angle adjusted more negative. There is a specifrication for this setting, and you are likely at the end closer to zero, but you need to be at the end closer to the max. range. Since they have to check it, you may as well have them physically make the change to the max setting.
If the range is -0.1 to -0.7, then you are currently closer to -0.1, but want to be closer to -0.7. I don't know what the spec is, I just know you are not at the preferred setting.

Would a 2" spring lift be substantial enough to cause it? Obviously, it would make the upper ball joint move slightly forward, but would it be enough to cause his problem? ....and did the problem start immediately after installing the spring lift? On the other hand,...... Dry, worn ball joints won't allow the spindles to auto-return, they tend to stick.
Not for arguments sake, for discussions sake.

Jeff Strickland - 26 Aug 2007 01:47 GMT >>I wasn't very clear earlier. >> [quoted text clipped - 39 lines] > > Not for arguments sake, for discussions sake. No argument here. Anything that gives a bottom line of a caster problem needs to be looked at. I only gave the adjustment as the problem because that's what steering return usually turns out to be.
I also suggested that the proper caster is negative when the imaginary line through the centers of the ball joints and the spindle leans toward the rear. I am not a front end guy, so I might be really talking about positive caster.
In any case, the imaginary line should lean to the rear of the vehicle for proper steering response to and from center.
The ball joints could be worn, but in all of my years owning literally dozens of cars, I replaced ball joints on one of them, and it did not fix the problem I was trying to fix. Granted, offroading takes a toll on ball joints, but offroading also takes a toll on lots of stuff, and for steering from center, I'll still go with the Caster Angle.

I'm still guessing ball joints in this case.

Bill Spiliotopoulos - 27 Aug 2007 13:37 GMT >>I wasn't very clear earlier. >> [quoted text clipped - 41 lines] > > Spdloader Whith a 2" lift the caster decreases from 7 to 5 degrees. Thats because the upper arm joint on the axle moves slightly forward when the axle drops, and the lower arm joint on the axle moves backwards.
5 degrees of caster is outside the 6-8 degrees range given by the manufacturer. But still not enough alone to prevent self centering. Another problem such as the balljoint failure must co-exist, that together with the reduced self-centering force has become apparent.
