2011 Sorento LX
can I just do struts only?
I didnt replace springs either but might do the rear at some point as the car sits lower in back. not a big deal yet.FWIW, I chose to replace only the struts and shocks (along with the strut mounts), and re-use the original springs. Our car had about 267K miles on it at the time. I saw a video on YouTube recommending this route, as they said that many of the spings included in the quick struts had smaller diameter and/or fewer coils than the originals. I got the free spring compressor loaner kit from AutoZone and did it myself; not too hard, but you have to be sure the strut mounts are aligned correctly or you'll have issues (don't ask how I know ).
However, if you have gone the quick strut route and are happy with the results, then that's great.
