Does anyone have book to let me know the torque pre-load for the front wheel bearings for a 1986 K/5 Blazer 4WD?
Thanks,
John

According to the Chilton's book I have.
"Adjust the bearings by rotating the hub and torquing the inner adjusting nut to 50 ft lbs. then loosening it and retorquing to 35 ft lbs., still rotating the hub. Next, back the nut off 3/8 turn or less. Turn the nut to the nearest hole in the lockwasher. Install the outer locknut and torque to a minimum of 80 ft lbs. There should be 0.001-0.010 in bearing end play. This can be measured with a dial indicator."

Thanks,
My son needs to pick up some manuals on this, I know with the 4WD there is a lot going on in there.

the inner adjuster will have a tit that fits into one of the holes in the lock ring. I have seen many that were smashed in between the holes. if a hole doesn't line up, turn the ring around. adjust the inner nut to line up. the specialty socket for 4X4 is the only way to go. if you're doing a bearing repack, don't forget the torrington bearing inside the spindle. it's often overlooked
