I havent been able to find anyone with the same problems who owns an 07 grand prix gxp with the 5.3 liter v8. My problem is this. I bought the car used with 150,000 miles on it. When i purchased it the rear tires had a thin section peeling off of the sidewalls. I assumed, going with the light scratch on the rims that the previous owner had just scraped the curb. I have since put about 5,000 miles on this car, and I have realized that the rear struts are nearly shot. When i have passengers in the back seat, the struts sag, and the tire rubs on the top of the fender, digging into the sidewall.
I have searched for new rear struts fitting this GM performance package suspension for the 18 inch wheels, but to no avail. I want to replace the entire strut assembly; strut, spring, and bearing plate. i can't find it. With the gxp GM put on the bilstein shocks, which i would rather stay away from... The dealer offers only the strut for $300 a piece...
has anyone had this same problem? does anyone know where i can find this complete rear strut assembly? I can find tons of strut assembly's for the grand prix gt, and others, but not the gxp with 18 inch wheels. Please help...
