Title: 1986 Silverado 2wd differential
Post by: cisco8604 on January 02, 2017, 10:55:15 pm

My truck has a new motor and rebuilt transmission but it's not moving replaced transmission with a new one still no movement both transmissions go in to gear . They only work in high rpm. I replaced governor gear, module, flushed lines , changed filters, I have a new vacuum line hooked up new coolant lines. I took off the differential cover no metal shavings. I put my truck on blocks dropped drive shaft transmission changes gears fine I put the shaft back on  no movement. Drive shaft does have about 3-4 inches of play maybe to short

so with everything connected the truck won't move at all?
Is the driveshaft yoke engaged into the trans?

Is the rear axle locked up?  This is a 2WD truck, right?
