I just bought a couple of struts to replace the worn out ones on the back of my 97 Corolla. I need to buy a strut spring compressor tool to remove the springs from the old struts but I'm not sure what to get. I found this, http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=3980, tool at harbor freight and another one for 40 dollars. Would the cheaper one be adequate to remove the springs? I've never done this before and I've heard that some spring compressor tools can slip. I can also take the struts to a shop here and they will switch them out for 30 bucks a piece.
