LAND ROVER SERIES III SPRINGS (REAR SIDE)


The springs are handed and have different rates for each side, but the fact that your offside rear spring appears flat does suggest it has weakened. To confirm which axle is causing the lean, jack the front up under the center of the chassis until the front wheels are off the ground. If the rear of the vehicle now sits level, you’ll know the fault is with front springs.
Do the same at the back of the chassis to make double sure, but ensure you have the jack positioned exactly under the center line of the vehicle. It’s possible that spring on both axle weakened.  Before buying new springs, slacken the shackle bolts to confirm that the shackle will move, and slacken the spring eye bolts, too if you’re unable to revolve the bolt after slacking, it will be seized and need freeing off. You’ll need to jack the axle up to take the weight off the suspension.
An 88 inch petrol series III has nine leaf springs on the front and 11 on the rear a 109 have 11 leaf springs on the front and 10 on the rear. The driver side springs are more cambered than those on the passenger side, but you won’t to be able to check the static measurement of these until the springs have been taken off and even then natural shape change over time will have changed the actual dimensions.
If you’re replacing the springs, we recommend using standard specification leaf springs with standard dampers from a reputable supplier to ensure the rating is accurate. Parabolic spring with dampers of a matching specification will give greater axle articulation if you need it over extreme terrain and, in theory, a softer ride. However, if the parabolic and dampers are incorrectly matched, the ride could be very bouncy.
