So my 2005 f150 with a 4.6 v8, 215000 miles, the passenger cv axle binds up when i have it jacked up, but the driverside doesn't, but when the cv axle is disconnect, both the axle and cv axle spin freely, but as soon as i bolted it back together, it binds up again, when im driving it vibrates when im turning, it feels like it's stuck in 4 wheel drive, but only the passenger side, transmission still shifts like a dream and goes in and out of 4 wheel drive when I want it too, just the passenger side seems like it's binding up when I Jack it up and try to spin it.
make sure it is the correct axle for the truck. Make sure it's fully inserted into the differntial (C-clip should snap into place). The axle could just be defective. If both sides are the same length you could try swapping them.
The old one was doing it, and now the new one is, but its only when they bolt together
then something in your suspension isn't straight. Either you hit something or it's very worn out.
There was actually no vaccum going to the actuator, so it was stuck, now that we fixed the vaccum issue, it got freed up, now there is just a grinding noise on the passenger side, so either the actuator is now bad or the wheel bearing is worn, which one will it be? The grinding noise is only during acceleration.
my money would be on the front differential
Most likely the actuator now, since now the 4wd actually engages and the light comes on I have a strong feeling it's the actuator, im gonna do that first because that will cost less money to fix and its something that I can do, if it doesn't solve the problem then I will most likely just have a professional check the transfer case and front differential out to make sure that they are engaging properly
