Any advice on tonearm rewiring for an MMF 5.1?

[CasualKiller]

So when I purchased my nice Grado Platinum off John I accidentally broke one of my tonearm wires. I was removing my old cartridge and when pulling on the clip my tweezers slipped and ripped the wire lol.

I managed to solder the end back on and hook everything up but it's just not the same. So I ordered some brand new Cardas tonearm wire and clips (cryo treated) and I'm going to redo everything.

I have plenty of experience soldering but I've never actually removed a tonearm before. Do you have to fully disassemble it or can you just tie everything down to prevent movement and remove the whole tonearm?

Looking for tips/pointers, I'm fairly confident I can do this with minimal fuss, I just want to know what the worst case scenarios may be etc.
