Hi.

There was recent discussion on the forum regarding how to deal with
a broken leaf spring.

I am wondering what can be done in the event of a broken coil.

I am assuming that a weld or sleeve type repair is impractical given
the forces involved and that a log between the axle and chassis to make
the whole thing solid is the go (assuming the coil breaks in the middle
making each part half the original length).

Can anyone shed light on alternatives.

I am coming from an 80 series live axle viewpoint - but would also be interested
in repairs for an IFS type suspension.

We were discussing the use of the Clampit gizmo on another thread. This is another occasion where I would use this device. I have seen shackle springs repaired using a Clampit and would think it would work on coils also if gently driven in emergencies. I would try to overlap the broken ends of the spring and join them with as many coils of wire as i could get around them. The bigger sized unit with heavier wire would be better, but the smaller units can make some pretty amazing joins.

No, i'm not an agent for them.

G'day Rob
Once broke a rear coil on the 80 out in the sticks and managed to drive hundreds of kms to get it fixed. The top bit just sort of jammed itself into the bottom bit and although it made a horrible noise on the bigger compressions it was fine to drive on (a bit slower than normal mind you). Perhaps I was just lucky! Now always carry a spare for longer trips away from civilisation.
