I dont own a set of ramps, but I was able to take a close look for any clearance issues. Every thing looks ok. I might want to add, that I dont hear the noise when I first start driving. It usually take about 10 to 15 minutes of driving before the sound appears. As if something needs to warm up before it starts to tick. Its the same weather I warm up the engine or hop in the car and drive without warming up the engine. Dont know if that helps. Also, the ticking is definitely coming from the rear of the vehicle. When I drive pass a concrete barrier, I can hear the tick even after my front tires pass the barrier and I hear it until my rear tires pass. I mean to say that I hear it all the time, it is just louder when I pass by something that the noise can reflect off of and it is louder to me then. I have not been able to change the rear wheel hub assemblys yet. Still shopping around. Does anyone have any suggestions for a good hub assembly. Im leaning toward Moog because of the cost. Are they any good? Thanks for all your feedback.
