Attaching a leaf spring to a chassis
allowing the spring to alter it's effective length when flexing
leaf spring front pivot bolt 115 ft/lbs leaf spring rear upper shackle bolt 115 ft/lbs leaf spring lower shackle bolt 80 ft/lbs
I believe its called a rear leaf shackle.
The bushings are pressed into the eye of the leaf spring on each end. The leaf spring should be removed and the old bushing pressed out on a shop press then press a new bushing pressed back in. In the old days I used to burn the old rubber out of the bushing then chisel out what is left.
if the axle is on top of the spring: get a pair of longer front spring shackle if the spring is under the axle: Get a pair of spring blocks.
The longevity of any leaf spring shackle and hanger depends on a few factors. For example, the age of the vehicle, frequency of the usage of the vehicle, the condition of the road and the weather where the vehicle operates etc. Naturally, in an older and heavily driven vehicle in a rough weather condition, the hanger and shackle might not last long. Whereas, in a well-maintained automobile, the springs can last more than 1,00,000 miles. An average lifespan of a set of leaf springs is around 2,00,000 miles.
I lift them on the frame rail next to the leaf spring shackle.
The front end is bracketed to prevent shifting of the axle. The rear is shackled, so that as pressure is exerted and removed, and the spring exspands and retracts, it will have room to move.
A set of leaf spring that is so mounted that it is at right angles to the length of the Vehicle is known as the transverse leaf spring.
the eye of a leaf spring, assuming u mean the eye at end of spring, is used to bolt the spring to the vehicle
To install shackles on your CJ7, first, lift the vehicle and support it securely on jack stands. Remove the existing shackle bolts and bushings from the leaf spring and frame. Align the new shackles with the leaf spring and frame mounting points, then insert the bolts and tighten them to the manufacturer's specifications. Finally, double-check the alignment and ensure all hardware is securely fastened before lowering the vehicle.
