Got some questions about the operation of the push button 4wd on my 93 EB. I am use to the seamless in and out operation of the system on my 2000 Explorer but when i hit the button on my EB FSB it seem to kind of clunk and groan a bit going in and out. I just tried it for the first time tonight as we had some snow here. Turning around in my back lot the steering wheel has a kind of a wobble when engaged and turning but out on the road going straight it did not seem to have it. It did seem to complain a bit with an ocasional thump or dull clunk kind of sound but for the most part not bad down the road. When i disengage its kind of hard to tell if its still in or out, seems harsh when it eventually pops out. Are there better hubs out there that work smoother the the stock auto hubs? Do i need to do anything other then hit the button when i want to engage/disengage (is this an on the fly operation like my Explorer). Or are these signs of other problems i should look into. Thanks all.
