Am I in trouble here? 86 C15 differential


Junior Member
Hi-Vehicle is a 86 GMC C1500. The front differential-driveshaft oil seal was leaking so I unhooked the driveshaft and removed the pinion flange nut BUT I didn't check the pre-load on the nut before I took it off or I didn't mark the position of the nut. So, how do I get this thing back together now?? The manual says you can torque it down about 8-15 in. lbs. (anymore and you'll ruin the collapsible spacer) but I don't want to shell out big $$ for an inch-lb. torque wrench. Is there any other way out of this predicament? Thanks for any insight
