Last night, looking at the rig from behind, I noticed that left side of the rig seemed little lower than the right. So, I went under and checked to see if there were any leaks in shocks... no leaks... then I measured the length of each shock... hmmm, left rear shock has droped about half of an inch compared to the right. Will replacing shock correct the problem? do I need to replace coil springs too? I am not looking at the lift at this moment so OEM parts will do. Thanks in advance.
