If you aren't sure if it needs something then my experience may help. When I bought my jeep and before i was part of the CJA, I brought it to the folks at Brokenaxle to go over and let me know what I'd need to do to go offroading, and come home.
The Guys at Brokenaxle are active in the CJA so this recommendation may come across as "supported" or something... There are other offroad shops in Calgary too, but My experience was great.
