Rear hub nut torque setting/rear bearing help

[Hoppo1979]

Hi guys, I replaced the rear discs/bearing when I first bought the car as the one rear bearing was toast. I bought Pagid discs with bearings pre set. The bearings have covered about 300 miles and are now droning like mad. At the time I fitted them I had no torque wrench so I nipped the big hub nut up with a breaker bar so it was fairly tight (didn't go all he-man just tightened properly.

ive done some googling and found 175nm banded around as a setting, just tried it and sheared the socket extension off! So the million dollar (and probably unanswerable) question is are the bearings over tightened or far too loose??

I appreciate its a very open ended question but would welcome peoples thoughts. Car passed mot yesterday with no play in rear bearings.

Probably a useless post but I've always done them F T with a breaker bar & been fine

Mate don't worry its a bit of an unanswerable question, just looking for any ideas/guidance. They're noisy as fcuk so something's amiss. But no play at all. I can't imagine they're wrecked after 300 miles. I might dismantle, load the grease in again and torque up, see if that sorts it. Anyone with the correct torque setting would be great, not in Haynes and Google is no use.

Correction, it is 175nm, found it in another section of the Haynes.

Anyone got the part number for the new stub axle nyloc nut (the big one)?

77 03 034 250

Got an hour this morning so dismantled both rears, smeared a layer of grease over each bearing face after a clean up, rebuilt and torqued to 175nm as per Haynes, the bearings are now totally silent! I've ordered 2 new nuts just to be sure, but I'm a very happy bunny!

one thing I did notice is there is no big washer that goes on behind the nut, just the flanged nut itself. Is that correct?

Yes

are the rear spacer shims in place on both discs as well?
