Mine has a Detroit locker, it's an S&W case so doesn't have the 'fill til it runs back out' filler hole.
I bought 3 litres of goop ages ago on someone's advice on here but just want to check thats right?

I was told & have read between 2.5 - 3 Quarts for a 9", never seen it quoted in Litres.

If running a Posi/ Detroit Locker, it is advisable you should run a Posi lube or similar. ( Approx 4 Pints + 1 Pint Posi Lube)

FYI
3 Litres = 5.28 Pints
4 Pints = 2.27 Litres
1 Pint = 0.57 Litres
1 Quart= 2 Pints = 1.14 Litres

I alway work on 1 quart is just about the same as 1 ltr

My conversion tables says 1 Quart = 0.946 Litres.

It does not help that US gallons and pints are a different size to ours.

1 Quart = 2 US Pints but only 1.66 UK Pints.

Thanks, i was probably told 3 quarts and got 3 litres. It was a while ago

I had just put 2 quarts/ litres in for pushing it around, i'll get some posi lube and top it up now, cheers!

Any idea who stocks posi lube?
Can't find it listed at any of the usual suspects (Real Steel, Summit, Jegs, Rally Design, Randys ring n pinion, Richmond gear)

Do i need an additive for a Detroit locker? Everything i'm reading says not because there's no clutch. Am i missing something?

"LOCKER is exactly that - meaning that in use the two axles can become locked- the infamous Detroit Locker for instance is a device that used no side gears (no spider gears) and no clutches (cone or otherwise) when sufficient power is applied the axles become LOCKED together. To allow a turn they RATCHET - often this ratchet action makes noise - I'm told this "noise" is even found offensive by some (never met "them" but I've heard that rumor all my life - ha ha) but back to business - these lockers have certain characteristics - understeer being one of them. New more modern designs address some of these pecularities. Since these rear axles use no clutches they require no "special" additives - just regular gear oil."

I'm not fussed about noise if thats the only benefit!

Hi Paul

I used about 4 quarts in mine with no additive ( both with a detroit and with a spool )

Mine was oem Ford casing, might be worth checking to see if the SW one is physically larger ?
