Did you go to the instructions link in the caption on the previous step and read it already? Did you follow steps 2-5 at that article? Good, now you have the factory strut top removed and the spring is compressed, ready for the new parts. &lt;br /&gt;
&lt;br /&gt;
With the strut assembly held in the spring compressor (red tool) as shown, compress the spring so that about 4-5&quot; of the strut protrudes above the upper spring winding.&lt;br /&gt;
&lt;br /&gt;
Again - follow steps 2-5 at this link BEFORE you get to this step!&lt;br /&gt;
