[QUOTE="vdubn, post: 16264191, member: 187123"] I recently purchased a 2001 Cobra Convertible, and have been working through some of the issues. Within the last 8k miles the owner put an Aluminator into the car, but the rest of the car has been pretty neglected. The car has an AJE K-member, AJE A-Arms, MM Caster/Camber plates and front coilovers. The main issues I have been having are as follows: - When I turn, I get a pretty loud pop from the pass side front - The steering feels extra heavy, and inconsistent (I figured it was alignment since it pulled to one side and didn't return to center) - Seems like a lot of vibration in general. I know convertibles have a lot of rattles, but this seems more than average So, first thing I did was to take the car to get aligned, and the alignment shop found that the K-member had some loose bolts and the alignment was way off. They adjusted it all within spec, but nothing they did affected the pop. They did find that the steering shaft was rubbing on the header almost constantly, which explains the heavy steering feel (which is still there after the alignment). So, I started with something simple... sway bar. Tonight I removed the end links, and the sway bar, and I found some interesting things. Here is the first thing I found. On the pass side (side with the loud pop) the AJE A-arm is cracked pretty bad at the end link mounting tab. I drove around without the sway bar, and low and behold.... no more pop. Tomorrow I will call AJE and see if they will warranty the arms. The drivers side is tweaked pretty good too, and the end link bushings are toast. See the pics.
