When I start up the TTA I let it sit and warm up a little. After doing so when I turn the wheels and put in reverse I can hear this groaning sound coming under the car on the driver side. The car is a t-top car so some creaking is to be expected but when I go over speed bumps mine is pretty excessive it sounds like. Some sub frame connectors are definitely in my near future but I am trying to see what is causing all of this. I have already installed a new poly ES trans mount. Does anyone elses TTA do this?
