Back Box Rattle

[Cotswold Pete]

Noticed over the weekend, and very much a rattle coming from the nearside backbox, on drive into work.

It sounds to me that it is the backbox, as 'poking' the box (thinking it might just be something rubbing) made no difference.

Sounded 'less-bad', by time I got to work, so my theory is the baffle is a little warmer.

Any thoughts, and if it is the box, is that a repalcement of whole section, or should I visit the chaps who did my Y-piece about 4 year ago so see if they can sort.

All comments welcome.

Rattles like this, IME, have come from the CATs not the exhaust box.

Either way a strap fixed around the offending unit may well cure it (did on the CAT on my MB)

when mine had an intermittent dreadful rattle over a certain place, like a string of baked bean tins, it transpired to be one heat shield that had come adrift after 23 years ...........  duly pulled out and disposed of, not replaced, seemed to be a bit superfluous tbh, bit over engineered my indy thought

Maybe I will jack the old lady up and have a look, to see if it could be that.

Yes also had the droopy heat shield, managed to repair with a large washer.

Ditto on my LS400, repaired with a large washer.

Pretty certain it is heat shield, only because when slamming down the boot this morning, there was that tinkling rattle like a badly tuned kids xylophone.

Need to roolte about in workshop for a washer.

when mine went, 3 of the 4 fixes ( or was it 2 of the 3?  )  had seemingly long perished and the 4th had then just gone, causing it to drop and be loose resting on top of the exhaust BUT it only rattled at that last time ..  it pulled away quite easily with a bit of tugging to remove it from it's challenging space ..  it was never going to just fall out for sure
