Why does my Silverado 4WD not fully engage?
It feels like it gets some power to the front wheels but they never fully engage. No service 4wd light comes on and 4wd buttons all work as they should. The hubs lock when 4wd is selected, and the truck shifts into low gear when 4lo is selected. The front wheels simply do not get the power that they should.
When does a 4 wheel drive axle fail?
The axle assembly seldom fails but rather the CV joints itself. In most cases, it is the outer CV joint that fails first since it does more work than the inner CV. A CV joint failure can happen when 4WD is engaged and the front wheel of your vehicle becomes airborne in a cross axle or rock climbing situation.
Can a 4WD vehicle have two locking differentials?
A 4WD vehicle that has two locking differentials provides true 4WD — all four wheels turn with the same amount of power no matter the situation. Even if the wheels on one side of your vehicle are completely off the ground, the wheels that are still on the ground will still continue to get a steady amount of torque.

What to do if front drive is not fully engaged?
To definitively say if the front driveshaft transfer case output is not being engaged, the best way is to get it on a lift, put it 4hi and later 4lo, and simply try it off the ground a little in drive. I would NOT do this on jackstands, tipping over a risk.

Why does my 4 wheel drive not engage?
Basically, The IWE requires constant vacuum pressure to keep the drivetrain in 2wd mode. Once there is a leak the pressure is lost and the hub will “dislocate” and attempt to engage 4H. If there is a leak or only partial vacuum pressure loss, the Hub won’t fully engage.
Why is my transfer case not engaged on my F150?
