Sam (Bones) Posted August 3, 2015 Share Posted August 3, 2015 I would use at least 70 ft lbs and some loctite Quote Link to comment Share on other sites More sharing options...
cbolt Posted August 3, 2015 Share Posted August 3, 2015 Funny I just did mine and cannot remember. I do know the top bolt has a small metal tab that is bent to prevent movement after tightening. Somewhere I have seen a chart which gives correct torque by bolt grade type, which may be helpful. Where did you find the 10-15ft requirement? I just checked my books and didn't see a specified tq for those bolts. Quote Link to comment Share on other sites More sharing options...
joseph Posted August 3, 2015 Author Share Posted August 3, 2015 i found the 10-15 ft lbs on 2 different websites. it does not seem like a lot of torque for those bolts. Quote Link to comment Share on other sites More sharing options...
MCfan Posted August 3, 2015 Share Posted August 3, 2015 Joseph,  The Chevrolet Chassis Service Manual for 1970 has a table of Torque Specifications for Brakes toward the back of that manual that lists the following for the Monte Carlo:  Support plate to steering knuckle . . . . . . . 140 ft-lbs (this is the larger upper bolt) Shield to steering knuckle nuts (hold bolt) . . . 70 ft-lbs Shield to steering knuckle bolts (hold nuts) . . 95 ft-lbs  The service procedure for replacing a steering knuckle on pages 3-9 and 3-10 mentions the use of lock nuts and refers to these specifications for installations so I believe they are correct.  Don't forget to bend the retaining tabs and Locktite is also a good insurance step, as Sam suggested.  Note that the two lower bolts are slightly different lengths and need to be positioned correctly.

black07ss Posted August 4, 2015 Share Posted August 4, 2015 i found the 10-15 ft lbs on 2 different websites. it does not seem like a lot of torque for those bolts. Are you sure this is not the torque for the caliper bolts. The ones the caliper slide on? Quote Link to comment Share on other sites More sharing options...
