.
That might be nearly almost a compliment Clive , perhaps you should see a doctor
It's not rubbing though there is a solid line from caliper to steering arm and the stainless runs from the arm to the chassis , i couldn't make it touch anything else even if i used a crowbar for leverage .
Time to take another pill then Shayne
As for some of the other constructive comments, I've a feeling even the front springs on Shayne's truck won't conduct, aren't you using neoprene spacers at the top of the springs on the front Shayne?
I was thinking a disconnected chassis earth braid might be encouraging starter current through the braids, but dismissed it straight away because the engine has no direct electrical connection to the axle.
But on second thoughts it does, at the wheels through the bearings and the driveshafts, gearbox, then engine, or vice versa. It's all metal to metal and grease conducts pretty well.
Worth checking your engine earths Shayne, it's easy to leave it/them off when doing a lot of spannering, as you have been lately.
All theory of course unless you run some controlled tests, but the damage is intense heat, the like you'd get from a starter in use, or as Rich suggested, the pull of a welder passing along a mere SS braid, but again, for it to be the welding, you'd have to have been earthing at the axle or the engine, no?
That bit doesn't make sense to me, yet.
