LEAF SPRING INFO
LEAF SPRINGS & SHACKLES ; SET UP
Have a look at the hangers and the springs and you will see there are rubber bushes surrounding the tubes where the bolts go through .
The bolts must be torqued up so that it grips the tube .
This means that when the suspension is moved up or down that the rubbers act as extra dampers .
The leaf springs to chassis should be tightened to 35 to 40 lbft
The leaf springs to shackles should be tightened to 35 to 40 lbft
The shackles to chassis should be tightened to 35 to 40 lbft
The way I set mine up is to assemble the suspension as normal with the car on LEVEL ground and the suspension as normal with an empty car but with the shackles just slack enough to be able to move freely .
Measure the distance to the ground from under the chassis at a point just behind where the rear wheel jacking point is .
Jack up the car on one side only to the point where the damper is FULLY extended and remeasure the distance to the ground from under the chassis at a point just behind where the rear wheel jacking point is .
Lower the car to the halfway measurement and tighten all the shackle bolts to the correct torque on that side
Do the same on the other side .
The reasoning behind this is that the rubber bushes will be flexed in equal distances
The above sequence might be the wrong way to do it but it has worked for me .
NOTE ;
Check the inside of the shackles where the leaf spring fits inside .
You might find that they have been cut into by the leaf spring .
This means that the torque setting will have slackened off .
Another thing is that the bolts often rust into the leaf springs and are difficult to remove .

I have been informed that a leaf spring had a very good condition sticker on it with the following letters / numbers on the sticker ;
MRLR 3861, WOR08660 .
I have no idea of the significance of those letters / numbers .
