Has anyone come across a guide or such for swapping of said item as mine reverberates now and from what i can see its down to one of the plastic locating lugs on the unit breaking apart I do like my Bass it appears!

Also the nuts appear plastic, is this to help dampen resonance from the unit as im wondering if its worth replacing them with nyloc or pinch nuts instead?

Also while im in there is it worth cleaning the sub and applying anything to the rubber like gummi pflege at all to keep it supple and last longer before the inevitable happens? FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
