Diff noise
When out in my Indy i can hear the diff. Bit hard to explain but it sounds fine, no grinding, no clonking just the whuring of gears. The reason for
asking is that i'm a bit worried that it may be a duff one. Yes it has oil in it and fresh oil at that. It is reasonably loud-ish but not
annoying and not noticable over about 45-50mph because of wind noise.
Can you lot hear your diff whuring away? Should i be concerned?
BTW, it's an LSD diff.

In a normal car your inside it so wouldnt hear it. Your ears are kinda next to it in a locost so you will hear it if that makes sense..
Nothing to worry about. Not unless its starts whining like a bastid..

I am also glad to hear that - I've been wondering about the noise from my diff as well...

Cheers Hicost, i'll get some Active 8 and pop some in just to ease my mind. If the V8 goes in i'll look at getting the diff either
reconditioned or replaced.

I can here my Escort diff (sort of shushing noise!) , but I've wondered if the Indy type arrangement would be noisy as the diff is soldly
bolted to the chassis just near your elbow with no flexibility to take out noise and vibration

Nail on the head there Dave!!
You're right about the solid mount too so i'm not worried anymore. If it starts grinding or banging i'll start to panic!!
Also i remember hearing your diff when out in your car last!

Dont use Active 8 on a LSD it will stop the LSD working.
Just leave it till you need to change it.
That is only true for a plate type diff. The Sierra LSD is a viscous unit that is sealed from the oil inside the diff housing, so it doesn't
care what type of oil it's running in (though obviously the CWP and bearings will).

Every Sierra diff I've ever heard in a solid mount makes that "shushing" noise.
The mounting onto RHS "amplifies" the bearing/gear noise.
As you say: unless it starts graunching/grinding, ignore it.
Experience is what you get when you don't get what you want!!!

A diff about to fail in a locost will make you stop, don't worry!!!!
Mechanical sympathy will kick in believe me!!!
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning
