I have a Ford 9 inch, from the 9 inch factory ( John's Industries ). I put the 3rd member in it and using new nuts and the special washers supplied, torqued all to 45 ft lbs per the instruction sheet.. I have 1 nut that likes to drip fluid. Now, I looked up a rear for a 78 ford pickup ( another 9 inch ) and torque specs on it was 40-70 ft lbs. So is it not tight enough , and thats the cause? Being it looked to me like the washers are a 1 time use product, I didn't try tighter. Opinions please...
