Learn about how to lower a Jetta. Lowering your vehicle can provide many benefits. First off, it is more visually appealing. Secondly it can improve handling and suspension. It is possible to lower your car by removing the old struts and replacing them with lower springs or coilovers or even cutting your current springs to the desired height. You must complete this process on each wheel and, although relatively easy, is rather time consuming. Follow these steps to lower a Jetta.
To lower a Jetta, you will need:
- Jack and jack stands
- Lug wrench
- Wrench set
- Replacement springs or coilovers
- Loosen the front wheel lug nuts with a lug wrench. Jack up the front of the Jetta and remove the lug nuts. Note that loosening the lug nuts on the wheels before you jack the car up makes them easier to remove because the wheels will not shift while the car is on the ground. Remove the front wheels.
- Locate the brake line bracket and remove it using a wrench. The brake line connects to the strut assembly. Make a mental note of the orientation of the brake line so that it is easier to reinstall later. Be cautious when working around the brake line. If you damage the line your brakes may not work properly and you will have to replace the system.
- Remove the lower strut bolts within the wheel well using a wrench. These two bolts secure the strut assembly to the vehicle and are usually extremely difficult to break loose.
- Open the hood and loosen the upper strut assembly bolt. This bolt is directly above the front wheel wells. Support the strut assembly as you remove this bolt with a spare jack or cement block–otherwise it will fall and may cause injury, as there is nothing else supporting it.
Adjust the new coilovers to the desired height. You can adjust the coilovers by loosening the bottom bolt and then twisting the top nut to the height that you want it. Tighten the bottom bolt.
- Install the new coilovers or springs designed to fit your Jetta using the bolts you removed from the old strut assembly. Tighten the bolts, securing the coilovers in place.
Reinstall the brake line bracket. Route it in the same fashion that it was before you removed it earlier.
Reinstall the wheel. Install the lug nuts, but do not tighten them yet. Lower the front of the vehicle and then tighten the lug nuts. Note that the front of the Jetta should be much lower now. If not the desired height, you will need to lift the car back up and further lower the coilvers.
- Loosen the rear wheel lug nuts with a lug wrench. Jack up the rear of the Jetta and remove the lug nuts from the wheels. Remove the wheels.
Remove the brake line bracket. Perform this in the same fashion as the front wheel.
- Open the trunk and remove the carpet trunk covering. Gently tug the carpeting to unsnap the clips that secure it in place. Locate the upper strut assembly bolt on each side.
Remove the rear strut assembly. Remove the two bolts securing the strut assembly within the wheel well. Remove the upper strut assembly bolt and support the strut assembly so that it does not fall.
- Adjust the coilover and install it following the same procedure as the front coilover. Ensure to properly tighten the bolts securely.
- Reinstall the rear brake line. Ensure that you route the line just as your removed it. Connect the wheel and lower the vehicle. Tighten the lug nuts.
- Always jack your Jetta up on a flat surface. Ensure that the car is in gear (manual) or in Park (automatic) and that the emergency brake is active.
- Use a longer wrench to loosen tough bolts. Longer wrenches give you more leverage and increase your applied force.
