DIY: Steering coupler/guibo

To start off, If you do anything to hurt or damage you or your car I am not to be held responsible. Proceed at your own risk.

Parts needed:
- steering coupler
P/N
Up to 4/2001- 32306752957
From 4/2001- 32301094703

^Part number 2 in picture above^

Tools needed:
- car ramps
- 12" socket extension
- 16mm socket
- 15mm socket
- 8mm socket or inverse torx
- 14" straight slot screw driver
- hammer
- Thread locker blue or red
- PB blaster
- #2 Phillips screw driver

lets begin....

1. Start by putting your car up on ramps making sure that your wheels are straight.


2. Lock your steering wheel in the straight position. This will stop you from wrecking your alignment.


3. Get under the car and remove the cover under the engine and the brace that goes across the car.
cover under engine-

Remove the screws and pop rivets

brace that goes under car-

There are 8 size 16mm bolts that hold this to the car.

Next we need to locate the steering coupler. The picture below was taken from the drivers side just behind the front tire.


4. You need to remove the 2 bolts on the steering coupler. This is where the 8mm socket or inverse torx come in. Also i found it helpful to have a 12" extension to get the wrench to where there is more room to turn.


The bolts look like this


5. Once the bolts are remove spray PB blaster on the coupler where it connects to the steering rack.


now let the PB blaster do its job


6. Next is where the big a$$ straight slot screw driver comes in handy. Take the screw driver and hammer and hit the coupler up toward the steering wheel. This takes a lot of effort and you can also move the steering rack if it helps for you, to remove the steering rack, take out the 2 15mm bolts that hold it to the car.

Big A$$ screw driver


The steering column is telescopic so it will move up as you hit the coupler off the steering rack.


7. Now that the old coupler is off we can clean up the spot where we sprayed the PB blaster then reinstall the new one. Make sure we put thread locker on the bolts before putting them back.


When putting the coupler back, the side that hooks to the steering rack has a slot that fits in the coupler so that you cant mess up your alignment. Also the side on the steering column has a notch in it where the bolt slides through.

Old vs. New-


Install is just the reverse of above.

Make sure to let the thread locker dry properly and then you can take your car out and enjoy nice, tight steering again.

Now enjoy some-

I do not condone drinking and driving so make sure you enjoy this AFTER you have test drove your car.

Go easy on me this is my first DIY write up!

I think you have to mark it before you take out old coupler otherwise the steering wheel turns and it is Hard to alighn it. That is what happened to me.

That is what the second step solves. You need to lock your wheel and your alignment won't be messed up. Like take the key out then shake the steering wheel till it locks.

It is easy. It just takes forever to free the coupler off the steering rack because of the rust.

Great DIY and subing for future reference!

I do have one correction...although it does not directly contribute to the DIY. The picture for the cover under the engine is wrong, that pic is for an aggregate protective plate. The correct cover that is held on by 7 screws is called an Engine Screening Cover.

Important if/when you order a new engine screening cover.

be sure to use something to lock up your steering wheel(don't let it turn infinity) or you could damage the clock spring. now all my horn / airbag won't work.

here is a link what happen to the clock spring.

Read my diy direction number 2! It says to lock your steering wheel and you won't hurt anything.

how loose was your steering and how did it feel afterwards?
my fcabs are fairly new i have new suspension.
my steering has maybe 1/2" play. possibly less.
i'm not sure if this is normal or if it can be improved.

I changed out this coupler a year ago. I had changed out the control arms and the bushings, and the car still felt off. As soon as I changed the guibo, felt like a new car. No more phantom lane changes when hitting uneven asphalt. No more drifting in the lane. It is amazing what $50 and an hour can do.

I replaced my coupler yesterday using this DIY. I also replaced the bolts (which had threadlocker already on them).

The DIY was so well done that it all went off without a hitch. The only difference was I didn't need PB Blaster. Considering the car has 133K, mine came off with relative ease. It took longer to get the car up and secure than it did taking off the coupler!

As far as how the car feels, I noticed the biggest difference on the highway ... it wants to stay in the lane I'm in.

Follow all the steps mentioned and you shouldn't have any troubles.

Thanks snowborder142190

Thanks! Also you can reuse the bolts even though they have thread locker on them.

If anyone needs the up to 04/2001 unit I have one (never installed) sitting in my apartment. I had a stupid attack and ordered the wrong piece.

They do something like 6 different things. They are really nice. I purchased them from autozone about 6 months ago for around $100. I'll see if I can find a link to some online for you.
