Have 1995 gmc 3500 w 6.5 diesel. The four wheel drive doesn't engage. Actuator goes in and out dropped front axle out and spacer washer had fell out of place put back together so it would be locked in four wheel drive worked well. Took out of four wheel drive will not engage again. Put silicone around spacer last time anything else I can try or why does that spacer not stay in place?
