When I removed the rear axle nuts I bolted a 3' length of angle iron onto the hub and placed it on a jack stand. I attached a socket on one end of a breaker bar and used a floor Jack on th other side to break it loose.
I don't have a torque wrench that breaks at the value called for in the Haynes book which I think is around 160ft#. I doubt that most of us garage guys have this tool. What do you all recommend for tightening the rear axle nuts. Thank You, Jack |

The best I can find is that you need ~220-250 ft-lbs.
If you target 250 ft-lbs (3000 inch-lbs) Get a cheater pipe for your breaker bar at least 3 ft long (unless you weigh less than 83 lbs). Take your weight (W) and use some algebra. Torque(T ft-lb) = Length(L ft) X Force(W lb) T = L X W If your weight is ~170lbs and you target torque is 250 ft-lbs: 250 = L X 170 solve for L L = 250/170 = 1.47 ft = 17.64 inches =~ 17 - 5/8 inches Make a mark on the cheater bar exactly 17-5/8 inches from the center of the socket. Torque by standing on that spot. (Math check => 17.625in * 170lbs = 2996.25 in/lbs) I take no responsibility if your foot slips or the socket slips or your breaker-bar snaps and you break an ankle. |

I take no responsibility if your foot slips or the socket slips or your breaker-bar snaps and you break an ankle. (IMG:style_emoticons/default/laugh.gif) I broke a no-name breaker bar while using a 4-foot cheater pipe to remove a rear axle nut to change out CV joints. I replaced the no-name bar with a 1/2 inch Craftsman breaker bar which did the trick. I reinstalled the nut using the body weight x distance torque technique. No ankles were broken in the process. (IMG:style_emoticons/default/laugh.gif) Years later I was looking for my 4-foot cheater pipe, which in the meantime had been loaned to two home mechanic friends on occasion, and I realized it had been left in the attic of a house that we had sold. Now I need a new cheater bar. (IMG:style_emoticons/default/sad.gif) |
