I have an '09 with 233,000 miles. When I make a sharp turn I hear a 'pop' coming from the front end. The dealer says the cracked bushings can't be replaced and I need to do the complete lower control arms. He's quoting ~$1500 for the job. If I do it, should I get the OEM spacers at the same time? Or should I go after-market and upgrade the whole suspension?
