Bumpy Ride Options

[BluuFire]

Okay, This has been driving me nuts for quite some time now...

A while back My car would get real rough when I push the gas when going more than about 20mph and so I took it in to the shop because I thought maybe it was a bad mount. They checked it out and said it had a bad mount so they replaced it. I was driving it home from the shop and it was still pretty rough when I would get into the gas. Well then it went away and drove perfectly for about 3 weeks. But now its back to doing it again but this time alot worse than it was. Because it comes and goes, I do not think that it would be a bent axle. What do you guys think? This is driving me crazy! Oh and also, I don't know if this is related to whats going on, but almost every time I take off from a stop there is some sort of loud metalic click. Most of the time it clicks when the wheels are somewhat turned and it only clicks sometimes when they are straight. I hope this doesnt sound confusing... Any help would be greatly appreciated!
