I have a 2002 Explorer 4WD -V8. Whenever I take off from a stop, I feel and hear a stuttering, grabbing, grinding noise... It goes away over say...10 mph or maybe 15 mph. It FEELS very similar to when you are in 4WD but on dry pavement.... It seems to be worse when I am turning, but that could be my imagination.
It started about six weeks ago. I tried changing the diff fluid, the transfer case fluid, the tranny fluid, and the front diff fluid (no change).
I changed the front bearing/hub assembly last week (no change).
I was going to change the rear wheel bearings next, but I really feel like it is not coming from the wheel bearings...
Today I jacked up the rear end with both tires off the ground. I started the car, put it in drive... the wheels go about 1/2 a turn & STOP! Then they go about 1/4 turn & STOP AGAIN! Then about a half a turn or so & stop again.
They are being "grabbed" by something.
With the engine off, I turn the wheels by hand... same thing-- they hit a stopping point. Then it lets go, and starts turning again... then it hits a stopping point. If I push HARD... I can force it on thought the "grab". This is exactly what happens while driving.
Suspecting the transfer case, or tranny, or front diff is locking up, I tried jacking up the FRONT end for the same experiment.
The front wheels turn freely with no issues.
I am now convinced that for some reason, either my transfer case or transmission is GRABBING.
What would cause this, and what would the solution be?
Ideas?
Anyone?
Bueller? ...anyone?
