Hey all, happy end of covid hell summer to you. So I bought a 2008 in March with only 49000k on it. Unfortunately I just found out left side front and back struts are bad which is causing lean. The SUV is from Galveston TX so I figure that salt air must have helped with the corrosion. The previous owners were an older couple. A auto mechanic wants to charge me $2 grand to replace all 4 strut assembly's. I am mechanically inclined so thinking of doing myself. The assembly should be easier than doing just the struts right? So questions -Who makes quality assembly's? -Is it better to go with a stronger one that is made for a Sport or AWD model to give better handling? -I would like to get a little more ground clearance too if there is a preferred one? -Lastly should I go for heavier duty sway bar linkages to also improve handling? Thank you in advance. Retro
