Alrighty.... well, I must confess that this question is about an IFS truck, but its pretty universal so you wizards should be able to take this one no sweat. (bear with me, I'm actively looking for a straight axel truck.) When I drive down the road in my current truck, the 4wd lever vibrates and wiggles back and forth. The unit works perfectly and there is no audible noise at all, nor can you feel it wiggle unless you hold on to it. Is this bad driveline angle or is it just loose linkage, etc... Any help you can offer me would be helpful. I'm looking to sell the truck soon and I think that thing wiggling all arround would be kinda a killer to a potential sale.
