16. Indexing the Spring (Mock Up)
With the a-arm hanging down, grab the coil spring and place the up into the upper
pocket. Some car models will need to be clocked at a certain angle to match up with
the index. Use some “white out” and mark the frame and the coil to give you a guide
when you are ready to install it for real. If your car does not have the upper indexing,
then you can skip this step.
17. Install the Spring
Rotate the a-arm up and place a jack underneath. Place the spring up into the upper
pocket and index it using your white out guide. Clock the a-arm isolator so the end of
the coil matches up with the index of the isolator. Slowly jack the arm up while pushing
the bottom half of the spring inboard into the isolator pocket. This step will be easy with
aftermarket lowering springs and difficult with OEM stock springs. For OEM stock
springs, you may need to use a series of pry bars to pop the bottom end into the pocket.
