Hi all,
So a few things. I have been noticing a clunking sound that appears to be coming from the rear of the car. It happens mainly when I transition from a "coasting" condition to giving substantial throttle input quickly. I dont normally drive this way, however, I can replicate the condition basically on demand. Also, I get a rapid clunking sound when going onto a driveway, which could potentially be related. I had it on a lift today and noticed some wear in the sway bar mounts and noticed what seemed to me like a lot of rotational play in the driveshaft. Also, the passenger side wheel seems to not be centered in the wheel well. The driver's side seems to be more centered but the overall appearance makes it seem like the axle is crooked in its position. The car, to my knowledge, hasn't been in an accident, although anything is possible. Would adjustable lower control arms potentially aid in this situation?
The car has been lowered, maybe 1"-1.5" I am not sure by how much since I purchased the car with the suspension mods installed. The car has Steeda Lower Control Arms, Steeda Control Arm brackets, BMR Adjustable Panhard Bar, stock driveshaft and stock UCA. I have been modifying the engine namely with a 2.6 upper pulley, Lund tune, JLT CAI, 65MM Throttle Body, VMP Inlet Elbow and colder plugs.
I guess I want input on whether this could be a driveshaft issue, or perhaps a axle gear backlash issue, or maybe just plain old extra NVH from the added stiffness of the aftermarket rear suspension in combination with more power? I haven't been able to find a good forum post that satisfied my want to find out what causes the noises.
Thanks in advance.
