Our Slip rear Diff helps us to get out of situations where one wheel is bogged and the other is on firm ground, this has happened only a few times, no slip diff I would use my winch or high lift jack etc.

I put Nu lon in sump, both diffs transfer case and gearbox of our Cruiser. Mate tells me that it should not be put in slip diffs defeats the purpose.

The TD Cruiser is towing just under 2500Kg and I believe the Nu lon helps.

Comments appreciated.

Usually not good Peter

I don't know which cruiser diff it is - but in general they rely or pressurized friction plates.

This holds wheels to-gether till one slips over the level of friction provided.

If you reduce the friction , you reduce the L.S. effect.

Usually you need special LSD Oil.

From what I understand ( and that may be incorrect ) the Nu Lon reduces friction so would reduce the effectivness of the diff in those situations.

I would email the NuLon site and check with them.

Or fit diff lockers :-)

Perhaps you could consider contacting a transmission specialist for their advice.

Might seem a little out there, but I would think seeing as they might repair and service diffs, etc they might know a little more.

I am putting the Nu lon in to reduce wear and heat while towing, do not care about problems when bogged.

But will the Nu lon affect the diff for the towing heavy load aspect. Will follow up with the supplier, but of course the safe answer for them is do not use it.

Thanks D200DUG,
looked up the site and the company says the G 70 is suitable for Slip Diffs, have been using it for 20 odd years must have done the research at the time, but the grey matter could not remember.

Spell the product with a blank, to make it harder for the search engines to pick the subject up and briadcast to the world on the Net.

You DO NOT put NuLon additives in a differential with friction plates as previous reply. If you keep up the oil changes in the diff, even going as far as changing more frequently, with the manufacturers oil specifications,the diff will still be going strong when the body has long gone to the recyclers, if your model Toyota diff is a good design.
My recommendation as a Fitter/component rebuilder/Maintenance Planner if you are worried, is to go to Caterpillar or Komatsu and get an Oil Analysis bottle, learn how to take samples correctly, and get it analysed on a periodical schedule. This will tell you if the oil is breaking down from heat,the amount of which metals are present telling you which diff parts are wearing too rapid - if there is a problem, or if there is water ingress. The sampling will also establish what preventative maintenance - if at all - is required before going on any long trips.
The differential has been designed to handle the max towing rating with a specified oil and 2.5t is not much (maybe for a Tojo it is ! dig dig).
If you add this, you may find yourself at the bottom of a hill with no drive, an expensive rebuild replacing the friction discs and cleaning the other parts, and lots of swearwords emanating from your mouth.
Just replace the oil regular as it's a quick, cheap, easy job and looking at the oil will tell you whats going on inside.

I stand corrected having a look at what is now available for gear chatter. There is specific additives for the LSD's.

Cannot see any problems with diffs, but I have grave doubts about putting anything with solids in my engine. Firstly the oil filter will filter some out , but the biggest worry I see is blocked oil galleries , and less free ring movement.
