Is such a product still available in Australia ?

What does lead do for grease?
-
Noise reduction and cushioning.
-
use graphite grease
-
Thanks. Lead would be better, thinking about mixing my own batch.

Mostly prohibited and withdrawn from general public sale. Industrial use in controlled areas. Ultra fine lead particles easily adsorbed via the skin easier via cuts and abrasions , can also be ingested orally. Lead toxins gets in ya and like mercury stays in ya . Use of modern graphite based is just as good lubrication or better.
Think to yourself my friend ,Why were leaded petrol and lead based paints removed from sale???? :(
-
Thanks, I have runs test with (MoS2) Molybdenum disulfide grease, and seems okay. Gears are quiet and engage easily.

I pulled the rear seats permanently out of my wagon recently.
I could then hear the diff.
noise is wear.
I changed the diff oil before I went to Victoria and put a wee bit of Molybdenum disulphide in,,,,,
it is now as quiet as a lamb on a hamburger. Good shit.
-
ive got some noise in my diff as well and I was going to try moreys in it as its very thick but ill try the m/disulphide in it so where do you buy it/is it a grease or just a oil?
-
I had a customer copmplaining about a whine in the diff,
I told him it was a matter of apinion. :o
On lubricants, lead is a health problem, plus it settles out, graphite works well but it should not be used on ball or roller bearings, as it rolls into lumps under the roller or ball and significantly shortens bearing life. Molybden di sulphide is far superior for minimum friction and long life. The old Bardahl product is excellent for protection of friction but is corrosive on steel in the long term and highly destructive on plain bearings.

Probably because I'm creature of habit I still use the Pro-Ma mbl grease in my bearings ???

Might try this. Thanks for posting. I
I have the back gear assembly installed on a wooden fixture, so testing is easy.

The micro-metallic particles dispersed throughout the MBL Grease are spherical in shape and act as millions of tiny ball bearings between two surfaces, greatly reducing friction. Under high pressure application, these spherical micro-metallic particles are deformed and flattened to fill up any pits, scores or irregularities which occur in the surfaces to be lubricated. The unique properties of the micro-metallic particles provide lubrication, film strength and heat dissipation.

I put Pro-Ma additives in my 40 series landcruiser gearbox/transfer/diffs from back in 1983 and their still going strong without a spanner put on em ;)
-
Another memory about Bardahl, one of my teen mates bought a 1937 Standard Ten sedan, we put Bardahl in the gearbox it had steel face to steel face synchromesh clutches, result-the synchro never worked again!
Their anti-friction claims were ligit!

Don't go for thick, it draws energy resulting in fuel increases that add up over the miles and years.
This a one liter bottle I bought from Blackwoods, long ago.

It was a small amount of this, added to an oil change that just shut my Diff up.
I have used this extensively on heavy plant and equip in the mining industry etc, in the day, to keep worn out gearboxes, diffs etc alive and extend duty cycles until the components for tear-down were in.
I serviced auto for a while, one customer had a howling 173 HQ s/w diff from towing a caravan around Oz three times(seasonal employment).
I put three 60Gram tubes in that, it only took three weeks to quieten.
I have built/optimised 72degree V6 Cosworth/Mercury formula outboards. They download RPM peaks of up to 14,500 when free air prop-walking(incredible engines, near to indestructible when balanced and then "Harmonised" correctly), I always added it to their right angle drive gearcases, I still do, even to my smaller outboards.

It will obviously quieten a LSD, but don't expect it to transfer drive away from the slipping wheel as well, or at all if it is badly worn ;)

many moons ago a relative had a skyline that was well down on compression and the oil rings were knackered. it had been treated with Nulon engine additive. he loaned it to a company we were working for to take 4 guys out to site every day (80km each way) we would top up the engine with oil from the loaders used sump oil drum on Monday and it would be empty on Wednesday (dead empty as the smoke trail would stop and the oil pressure gauge would drop ;D) it then do thurs and Friday trips and Monday out with no oil in the engine. amazing..went like sh*t of a shanghai as well, even with the four of us in it..
have a huge respect for nulon after that display
-
thanks for the link Mick D ill get 2 tubes and mix it in with the new oil before it goes in the diff and hopefully ill get another 100k out of it before its completely stuffed as its only just making a little whine right now and barely noticeable ;)

Found this video. I will definitely try MBL (metal based lubricant)

This has been a good discussion.
