Strange part on differential/steering damper

Upon visiting a friend he showed me a set of 90/110/defender axles he bought to go under his SIII.

The background: swapped the original 2.25 diesel for a 90HP Peugeot diesel, need to change the old gearbox too for a stronger LT77/LT230, need to change the old axles too because of the different gear ratio.

Both of us are wondering what the purpose is of the round metal disc (maybe

5" dia, maybe 1-2" thick, did'nt take a measurement) that is fixed to the front axle's differential sort of on the end of the steering damper.

Another intrigueing part is the small dia steel cable fixed to the differential/steering damper on one side while fixed with the other end to a washer on the very end of the assembly. As if it is there to catch the metal disc in case it comes loose.

Can somebody shed some light on these mysterious parts? Why are they there, what do they do???

TIA, Gio

It's a harmonic damper....

So, it dampes harmonics, still no clue what that means for driveability of the vehicle. Could you please elaborate?

Thanks, Gio

It's like a shock absorber for vibrations and harmonics from the gears and axles. Supposed to make things a bit smoother and more driveable.

You'll also find one on rear diff and transfer box (large triangular weights bolted to rear of transfer.).
