Im hoping that this is where i can post this. Ive had a 97 4.6 liter Thunderbird for 3 years. The whole time Ive had it it makes a weird noise when driving. No matter how long it idles or how long its been driven there is a crunch noise when i start to drive. Ill go a couple of feet and itll make the sound. No physical feelings to it either. Its only after it starts up not when stopping. Its got fluids in the trans and a new motor. I cant deduce what this could be.
