Is your steering wheel sloppy? Unresponsive in the first bit of a turn? Well then your steering gearbox may need to be adjusted.

Legal:
I, nor jeepforum, nor anyone else take responsibility for your screwups. The steering system is critical to the performance of your car both on road and off. This writeup is meant as a guide to adjusting the steering gearbox only and should not be taken as a bible or fact. Please consult a professional if you feel that you may compromise your vehicle.
/Legal

The first step to all of this is to figure out where the sloppiness is coming from. I found out it was my steering box by grabing the steering shaft right above the steering box and found that i could move it about 1/8th-1/4th of a turn with out the pitarm moving at all. Other posibilities of play is in the draglink/tie rods, play at the ujoints in the steering shafts and a number of other things. This writeup only applies if your gearbox is the culprit.

On top of the steering gearbox is a nut with a allen screw in it. This is the adjustment screw that you need to turn.

Total time: 30 mins

Tools needed:
5/8 wrench
3/8 wrench
Allen keys
Pliers

optional but help:
torque wrench/breaker bar
Pb Blaster

Step one:
Locate and remove the 4 bolts that hold on the front plastic jeep cover. (if you have removed your plastic jeep cover or installed a winch cover, skip this step or remove it.) They are 3/8 inch.
The plastic jeep cover is this thing:

The bolts are located here. There are two on each side:

Please excuse the glasses

The plastic lifts from the back:

The second step is to remove the plastic support bar.

Image


The bar also supports the front passanger brake line. It is held in by to black clips. The red circles are the location of the clips. The blue circles are where the bolts are located. The orange circle is the steering gear box. A pair of pliers should be used to squish the clip and push it through the holes as shown.

Image


Then remove the two screws at the end of the bar that hold it to the frame.

Image


Now you should be able to see the top of the steering gearbox.

The nut and the allen screw are circled in black. Heres a view after some pb blaster was sprayed on:

You will need to lossen up the nut. It is a 5/8ths nut. I had to use a torque wrench to break it lose. You only need to turn the nut about 3/4 to 1 turn if that.

Now, take a 5/8 wrench and put it on the nut. Take a allen key that fits into the allen screw and place it into the screw. Turning the screw clockwise will tighten the steering, to the left will loosen it. Turning the screw only a little bit, like 1/8th of a turn will have a great effect on your steering. Turning the allen key too far will bind the steering box gears and blow up your steering gearbox.

Image


I turned my allen screw about 1/4 of a turn. Then, take the allen key out and tighten up the nut. Jump in the jeep and turn it on. Is it tighter? If so your doing alright, if it is looser then you screwed up. The steering wheel should have a minimal amount of play in it but still a very little bit. If there is no play at all, you may have tightened it too far. Now, run around the block. Come back. You may need to adjust the allen screw a few times, each time checking the play in the steering wheel.

After you have it where you want it, make sure that the nut is tightened down. I tightened mine til it was snug and then a little bit more (1/8th of a turn). Put the support bar back in place, dont forget about the brake line clips. Bolt it down snugly. Put the plastic jeep cover back on snuging up the bolts. THe jeep cover will compress and break if you tighten it down too far so snug is good. Dont forget the antiseize so that when you go to do this again in a couple of years (or you get a winch) you wont have to fight with the bolts.

Congratulations. You have sucessfully adjusted your steering gearbox. Now, pray to the jeep gods and go run some trails.:thumbsup:

Well, it should be titled "How to kill a steering box in one easy lesson"!
That top set screw is the bearing preload screw, it has nothing at all to do with right/left slop of the steering wheel. Overtighten that and look for a new box soon. That needs an inch pound torque wrench on the pitman to adjust.
The right left slop is taken up by the 'adjuster plug'. This is the plug that the column feeds through.
You loosen off the big locking ring and you tighten the plug under it using a hammer and center punch or the proper spanner tool that looks like an angle grinder wheel remover.
You turn the adjuster plug all the way tight, then back it off about 1/8" of it's edge travel, then tighten up the big lock ring again.
Your steering wheel should now react properly.

where were you when I first came to this site, I didn't know about FAQ so I posted a req. for help (clearly stating that I could turn the shaft and the pit man arm didn't move ) wanting to know if that was an adjuster and all I got were people asking what size rim I was running and offset, I finally gave up on them and went for it, what a difference.

Sorry man, I guess I missed that thread.

Nice writeup sonofsam02. I did this back when I first got my Jeep. There wasn't much of anything about it on here back then either. A Bronco guy showed me how to do it. It took about a turn and a half, on my manual gearbox to get it right. You might want to say if you have to turn it that much, it's probably time to look for a new box. I have power steering now.:2thumbsup:

steering gear box

Son of sam...great post, thanks. I had some earlier post about my jeep, felt like I was driving a boat. I have owned thew jeep for a week now, I realized the problem was the steering, I had to turn the wheel a lot before any response. So today, I went and tried out the gear box adjustment. After the second tightening, My son was turning the wheel back and forth, I was watching the response of the tires. I worked my way back to the gear box, the whole thing was moving everytime the steering wheel move. Shut the jeep off to investigate, the steering box was barely held on by 1 bolt, I took it out with my fingers. After a trip to the hardware store, Ireplaced both boths, adjusted the gerar box back and she handles like a dream. Thanks for your help.:cheers2:

Nice step by step, the only part that killed me was after I tightened it all up, what good did me running around the block do??? The neighbors were all sorts of freaked out when they saw me running around the block all greasy and waving a ratchet. Other than that it worked like a charm. Boy was it hard to explain to the Cops that stopped me though that I was fixing my Jeep, they just kinda looked all puzzled and told me to walk calmly so as not to scare the children.

At least you got some exercise other than what you do at the back of your Jeep.:rofl:

Thanks i got off my butt and checked it.
Did the repair job and now I only have about 45* degrees of play. Before there was about 180*degrees play
How far down should the adjustment screw go down. To get the result ^, I had to move it down alot. 2 threads of the locking nut is showing.
I bought my first Jeep yesterday and expected to spend $200-$300 on a new gearbox so THANK YOU SO MUCH!!!!!
There is a rebuild kit for around $75 will that fix it?
 
#24 ·
Sounds like you need a new gearbox anyway. You shouldn't still have that much play. Mine was a manual too. You should look into converting to power steering. For about $300 you could buy rebuilt parts, new hoses, a polley, and a new belt. You'll never regret it.

I don't have the factory service manual infront of me, if that information is even contained in there.
How much it moves depends on if the previous owner moved it/ how far out it is.
There is a point where you should just replace the steering box. Where that is, I honestly don't know.
Mr B, who posted earlier in the thread had to turn his manual box 1 and a half turns.
The rebuild kit, is it just the seals, or does it include all new gears and the like?
