Hey everyone, hope someone can help out. I own a 2004 tacoma trd dblcab, and recently I noticed that the rear left side is sagging a bit, I actually measured both the left and right side and it seems that it is sagging almost an inch compared to the right rear. Is this a worn out spring or shock, or do I need to replace both. Truck has around 81,000 miles on it. I live in socal high desert in the wonderful city of Hesperia, so I constantly drive on dirt roads or on streets lined with pot holes. I don't think I can really afford to replace entire rear suspension right now so if I can go with one or the other it would be best.
