Hello
I have problem with my 4weel drive. When I put it in 4hi I can hear the sound of the actuators Engaging but when I start driving the wheels seam to be locking up for a second on each revolution and I can hear a wining sound. What could be the problem?
Thanks!

I also changed the rear end last year I am not sure if it has the same gear ratio as original would that cause problems if it was different ratio ?

Having different gear ratios between front and rear diffs will definitely cause issues in 4x4 mode.

Definately sounds like you have 2 different gears going on... They should match.
