I recently purchased a 2003 4.6is and immediately noticed a loud thump from the rear going over certain bumps and a loud creaking/thump from the rear when accelerating from a stop. I believe from research that it is the subframe bushings so my question is is it ok to drive the car until next Tuesday when they are getting replaced? I just worry about the issue pulling the bolts out of the body or possibly damaging/cracking the mounting points like an E46 M3.
