How long does S-diff last?

[fullmetal]

I'm still running the stock S-series diff behind my 4age and it seems to be beginning to whine, or it has for awhile and it was my friend who identified it. Doesn't sound terrible but it might be on it's way out. How long do these diffs go on in this state before they need changing?

I plan to go to T-series diff anyway but that was coming a little later.

if you treat it badly it might not last much longer, but if you treat it nice or dont put too much more power through it, it should last until you get a t series.

but anyway im sure you could find someone who has a spare s series centre that you could use in the meantime if you dont like the noise.

then again it could just be the bearings

hope that made sense

I reckon its the crown n pinion wheel... they're probably just scuffed... cuz maybe at one stage there wasnt enough oil in there...
Does the noise come on when ur on partial or no throttle...but if u floor it... the noise goes away...? If thats ur problem... its nothin major... and should still last for a while... Just make sure theres diff oil in there...
I personally wouldnt bother fixing it... just get the money together and go for a T series...

Floor it and the noise goes away... kinda, my exhaust note hides it

It's a constant noise you can hear while cruising, not overly loud or sounding like it's falling apart or about to break, just enough that you can hear it.

Thanks for advice I'll check the oil out.

iv been told that a S series has the same strenght as a T series

hahahahahahahhaa no..

My TRD 2 WAY LSD whines, but not diff whine.. like Supercharger whine... not like an i'm going to explode vibration humm.. i have had it rebuilt a few times (broken Axel swarf etc whet though it.. has done it the whole time, so i'm not concerned it's just the way it is

but yeh, i'd be keeping away from clutch dumps, and hard gear changes for a while.. throw a bit of oil in there.. anything diff/hipoid just to get it buy.. if you top up with lucas oil stabiliser it might queiten it down
