So I just installed my new Rallitek sway bars and endlinks.(Rallitek rears and AVO fronts) I did this all while the car was on the lift. While driving around now I hear occasionally, not consistantly what sounds like a flat tire. I know I'm going to hear more road noise, but it sounds like the flat tire. All the tires are fine and everything was torqued back to spec. I greased the reccomended parts with the supplied grease. It sometimes happens going straight, more times when turning. It definetly is coming from the front of the car. I looked under the car and nothing seems to have come loose or moved/shifted at all. Only thing I can think of is the torque wrench *popped* prematurely? The nut on the new endlinks were somewhat tough to turn(lock nut). I had a mechanic buddy of mine help me the entire way though the process. Any ideas what could be the problem? Thanks in advance!
