Hi guys, My diffs are not locking. I have tried on dirt roads at low speed making wide turns and nothing. I can hear the pump running, but the center lock will not engage. I have a new diaphragm to install but could use a little help on the procedure. I have read you need a "special puller"? what is it pulling? also does anyone know the socket size to get the electric switch sensor thing off, located in the center of the diaphragm housing? I am guessing 27mm or 28mm deep socket? I will have to go out and buy one would be nice to confirm the size.
thanks a ton,
