Driving the car home from purchasing it two weekends ago, I noticed that the truck's front diff has a low pitched whine coming from it. Is this normal for the 5.0L AWD system? I know it's the diff because when I apply load (lean into the the throttle), the pitch increases. When I let off the throttle and coast, the noise disappears completely.
I haven't checked the fluid level in the diff yet, but I have replaced the driver's side half-axle (started clicking) and when I did, no fluid drianed out upon removing the old half-shaft. I found this rather odd as every half-shaft that I have ever replaced has always leaked somce fluid.
What is the procedure for draining the front diff and refilling BTW? I know where the fill hole is, but do I have to remove the diff cover to drain the diff? It's semi-blocked by the front cross member and would be a PITA, or is there a drain plug that I am missing???
Thanks in advance for any insight you can provide
