Repair And Fix it

Coil springs are a part of the cars suspension system -- most notably on older model cars. They are a strong component, but not known for having a smooth ride. Not much more than extra large heavy duty springs, removing them to replace with new ones or do other work is a physical but not difficult task. Youll need to take care to avoid injury when compressing these springs during removal.

Instructions

1

Lift the end of the car you will be removing the coil springs from, and secure the tires on the opposite end with wheel blocks. Place the jack stands beneath the car frame.

2

Remove the tires from the working end of the vehicle and set aside. Remove the sway bar linkage and the shock absorber if there is one from one side.

3

Spray the coil spring nut and the surrounding parts with spray lubricant. Insert the coil spring compressor, and compress the coil by turning the nut on the tool. You may have to adjust the placement of the compressor so there is room for the turning screw to raise as you tighten the tool.

4

Place the floor jack beneath the lift arm, and raise just enough to take the tension off the coil spring nut. Remove the cotter pin from the lower ball joint nut, and loosen the nut.

5

Hit the spindle squarely with a mallet. This may take a few tries, but you will feel the pop when the ball joint bolt comes loose. The jack will hold everything in place.

6

Slowly lower the floor jack. The coil spring may or may not slide right out as you do so. If not caully remove it. Decompress the spring very caully from the coil compressor tool.

7

Repeat for the other side, then the other wheels if the car has coils springs on all four.

Dual exhaust is applicable on motorcycles, trucks and cars. Replacing dual exhaust with an aftermarket system may increase engine power, fuel efficiency and provide a better sound. Aesthetically appealing aftermarket dual exhaust pipes can also replace dull and aged components. Dents in the piping, corrosion, age spots and missing hardware are also reasons for dual exhaust piping replacement. Compromised dual exhaust pipes may increase backpressure within the piping, which decreases performance and suffocates the engine. Each replacement exhaust system will include installation instructions specific to the vehicle but there are general steps each process requires.

Removing Old Dual Exhaust

1

Open the hood and disconnect the negative battery cable. This black cable is marked with a negative symbol. Also follow this step when working on a motorcycle. Doing so will allow the vehicle computer to reset and recognize the new dual exhaust pipes after completing the install.

2

Lift the vehicle off the ground using jack stands. For four-wheeled vehicles place the parking brake on. Leave adequate room underneath to remove the exhaust components efficiently.

3

Lay the new dual exhaust piping adjacent to your vehicle and compare it to the old exhaust underneath the vehicle for reference to where each new part will go.

4

Spray the flange bolts and exhaust clamps mating the exhaust components together with penetrating oil. This will loosen them and make removal easier.

5

Unbolt the tailpipe from the muffler if applicable with the socket and wrench set. Some vehicles feature a retaining clip that clamps around the Y-pipe and muffler. If this is the case, bend the clip back with a flathead screwdriver.

6

Unplug the exhaust sensor located on the piping between the muffler and catalytic converter if applicable. Sensor locations vary by vehicle.

7

Remove the tailpipe and muffler assembly after unbolting each nut and from its bolt. Locate the exhaust hangers and lift the dual exhaust piping off the hook where necessary. You may also use the hacksaw and cut through the front muffler piping, towards the front of the car, for removal. Refer to the new exhaust installation instructions for specifics.

8

Leave the rubber grommets on the exhaust hangers when removing the exhaust components. If you were instructed to cut the old piping off, spray the newly cut section with oil, which will make sliding the new dual exhaust piping into place easier.

Installing New Exhaust

9

Install the new components from the front of the vehicle towards the rear. Follow the new exhaust instruction manual for directions.

10

Hang the new components on their corresponding hangers and then hand-tighten the necessary flange nuts. Do not torque them to the specification listed in the vehicle owner manual yet.

11

Center the new components before tightening each bolt to the required specification.

12

Reconnect the exhaust sensor and negative battery cable.

13

Start your vehicle and listen for exhaust leaks, which make a hissing noise. You may also strongly smell exhaust underneath the vehicle if it is leaking.
