Hello Dear Motor Lover! Are You taking notes on the adjustments of your car? If you’re a person who adores his car and takes care of it, you have my respect. I don’t realize why people just learn about driving but they don’t learn about adjusting tools.
It is a must and a plus for you to have the knowledge of different tools of your car. Know the know-how of installing the best leveling kit along with installing the lift kit. If you have done your homework on these already, it’s time for you to learn about installing a torsion bar.
That being said, I think you know by now what I’m going to talk about today. Yes, you guessed it right, today I’ll talk about how to adjust torsion bars. So without further chit chat, let’s dive in.
Why You Need to Adjust Torsion Bars?
You may say to yourself ‘why the heck would I want to adjust torsion bars?’ Well, here are some few reasons you may check.
- Maybe you just don’t like the ranked stance that comes with your big heavy duty Silverado if you have one.
- You need more clearance as you have changed your stock tires and put on the larger ones.
- Maybe it’s all about getting your truck level from side to side.
- If you want to have a drag race or sled pull, you need to lower them so that you can prevent the CV shaft breakage. This will also help you reduce toe-in while going down the track.
Things You Should Consider Before Adjusting Torsion Bars
- If you feel the need to adjust bars up or down more than one turn, you should go for an alignment.
- Always remember that the higher you raise the front end, the stiffer your ride will get. In this case, torsion bar keys like ‘green keys’ will come pretty handy.
- Using an Impact Wrench on these bolts can bring negative results.
Some Other Tools
- Floor Jack
- 2-Jack Stands
- 18mm Socket
- Tape Measure
- Breaking Bar
- Creeper or Cardboard
- Penetrating Lube
How You'll Adjust Torsion Bars
So that you don’t have to go through a hard time, I’ve provided the simplest steps possible to adjust torsion bars. Go through these steps and you’ll be able to adjust the torsion bars all by yourself.
For each side in the front, you need to take a beginning measurement, once you get your truck on your flat work area. Using a consistent spot, in this case, will come pretty handy. Measuring from the ground to the fender while keeping the tape measure level is a wise idea. Just make sure there are no obstructions on the surface where the truck is on. Notice if both the front tires are inflated equally. When all of these are cross-checked, write the measurements down.
Now using the floor jack, try to jack the front of the truck up. If you don’t have any idea how to jack the front of your truck, or you’re a newbie, position the floor jack in the center of your truck. Now It’s time to lift on the cross member that the front plastic skid plate and the aluminum oil pan skid plan meet at.
You got the jack stands with you, right? Well, it’s time to place your jack stands underneath the front of the truck.
Now, get your hands on the 18mm socket you’ve brought. Don’t forget the breaker bar/ratchet and some penetrating lube. Once you got all of them, roll them under your truck and locate the torsion bar cross member.
Now as it’s time to adjust them, you’re either taking them up or dropping them down. If you’re quite sure that you’ll need to adjust torsion bars a couple of times in the future, it’s going to be wise for you to just remove them and put plenty of anti-seize on them.
If you’re done with everything above, it’s time to raise the truck off of the jack stands and lower it to the ground.
Take your truck for a spin over some rough ground if you want to recheck your measurements.
However, you should always be careful, ‘cause if you’re not, you may end up cracking or deforming the plastic. Now, to make sure the front tires are in the air, you need to raise the truck up. This will ensure that for most of the part, the torsion bar is unloaded.
Can’t locate your torsion bar? Look right below where your rear driveshaft connects to the transfer case. See the two big black bars coming out of it? Voila! You’ve located the torsion bars.
The next step is to locate the torsion bar adjustment bolts. You’ll find them on the lower side of the cross member. Now to loosen them up, spray some penetrating lube on them.
Raising: To raise the front end of your truck properly, the first thing you need to do is get your truck level from side to side. Get your measurements right though. If the side of the driver measured 34.5” and the passenger side measured 34”, you need to add an extra 2 turns to the driver side over the passenger side.
Remember that you’re roughly having ¼” of lift with each complete turn of the bolt. Now, it’s up to you to decide how much you want to lift the front end and only go as much as needed.
Pick a reference point as you watch the socket pin so that you count the turns of your bolt. You can roll out from under the truck, once you know you have the correct amount of turns.
Lowering: It is best to just remove the bolts and set them in the cab while you reinstall them later if you’re talking about lowering the front end.
However, don’t forget their original measurement so that you don’t have the wrong alignment. You can simply mark the position of the key. You can also count the turns as an alternative if you want.
If you are Chevy lover and you want to know how to crank torsion bars on chevy 1500 or how to adjust torsion bars on chevy 2500hd, the procedure is pretty much the same.
But do remember that the normal coil or leaf springs won’t fit the torsion bars of Chevrolet cars and trucks. Besides, though there are few exceptions, you’ll find the rear torsion bar mount just behind the brake assembly on the frame rail in case of most Chevrolet models.
(Note: If you’re using a car lift, skip to step 4)
Your truck is your responsibility and you should be aware of that. A good driver not just drives the car and have fun. He takes care of his ‘beast’ like a mother takes care of her baby. This is why knowing about the mechanical issue and fixing them is a must.
Along with learning about different tools like a lift kit, knowing how to adjust a torsion bar is important. I think you’ll be able to adjust your torsion bar from now on, all by yourself.
