guys, I have an 98 ext cab Sonoma lowered with 2" spindles and a 2"angled block and a leaf removed in the rear. I've been noticing a loud noise lately coming from my truck. I can't really tell if it's the driver side front wheel or the drive shaft. It kinda sounds like a when something is rubbing or the sound you get when you have a lump in your tire. However, I don't have any type of vibration. The sound starts at about 15mph and gets louder and faster until about 75mph then I can't really hear it. The weird thing is that if I turn right, the sound gets louder and if I turn left, the sound goes quiet.Any ideas as to what I should check before taking it to a mechanic? Thanks
