When off the ground, engine off, I can freely spin the 2 front wheels, spinning either wheel will spin the front shaft. Spinning the front shaft by hand spins the left front wheel.
Engine running the rear wheels spin the second it is in D, the front wheels or front shaft from the TC do not spin unless I increase the engine speed upwards of 1500 rpm and then they barely move as if being braked or binding but when this is happening I can spin either wheel by hand easily.
I thought about the DSC causing this so I pressed the DSC button on the console, the yellow light came on the instrument panel but it did not have any effect on the problem.. I didn't think about unplugging or a fuse.
My next thought was the recently replaced left front cv axle as it does not spin as freely as the right front. I checked to make sure it was inserted fully, multiple times and it was. So, I removed it. After getting the clip to release I grabbed the shaft to pull it out and it easily extended at the inner boot, much more than I thought it should. I have replaced 5 or 6 on different vehicles and not one has extended like this. When I finally got it out I could not easily get it to retract back. I had to hold it vertically with that end on the ground then lift the axle up and then down smacking the ground, think of slide hammer, doing this multiple times until it finally retracted. I have it in my vice and when I extend that end I feels very rough, and the same goes for when I push it back, like there are notches or its catching inside the boot. I thought about removing that boot to inspect the joint and the cage but have not done so yet. I did order a new axle.
Can I run the vehicle, in the air, in drive, with that cv axle out of the differential to see if the issue still exists?
