Alright guys, I have a few problems with the car I need to diagnose and maybe you guys can help me out... * When I get on the car in 1st or 2nd w/ more than half throttle it seems as if there's a vibrating noise coming from the differential area. You can also feel a slight vibration on the floor as well, but you have to feel for it to actually feel it. When I got my 4:10's in they said that the posi is on it's way out so I'm assuming that's the case being that they we're put in about 8k ago. What do you guys think? Posi or no? * Also when the car warms up pretty good, like if the weather is over 80-85* and fully heated up, the car makes a humming/small vibrating noise when I turn the wheel. It's consistant with the turn too. I don't think it could be my pump because the belt would be screeching when I turn and it doesn't at all. Anyone out there with the same problem?
