Limited slip diff question

[daves]

funny you should bring up the bog hole thing cause last time we were out got stuck in one and my mates said only one back wheel was spinning.It has only spun one back for a while know but as i said it does seam to be getting better . I will let you know sometime over the weekend as we are going for a 4by.

There was also a thread somewhere talking about adding engine oil flush treatment to your diff for a 1000 or so k's before dropping the oil and adding fresh stuff. I think the idea was to clean the clutch plates. Sorry, I can't remember what the thread was called. I think it may have been by robo

Tap, crackle, pop

you could use the left foot brake technique to try to keep it locked in

thats why I tried it after reading it on a different thread and as I said has helped but is still no where as good as it was.Im thinking the guy that I bought it of might have had it shimmed and that was why it was so good before and now it might have loosened up,this weekend will test it right out we are heading out the back of woolgoolga(coffs area)cant wait.

I put the new oil in and it is definitely better but is still not as good as it was.I will run the new oil for a while and will let you how it goes

Reason you leave it in for 1000k , cleaner only works hot so I"m told, "sounds fair enough".
It seemed to work on Mav's lsd, did same thing about a yr ago.
The old stuff was very dirty when drained after being cleaned.
cheers

up date on lsd cleaning
Went out for a drive in the Wattagons Mts looking for a camping spot couple days ago.
Gave the LSD a work out in the dirt, it still working fine.
Went from not working at all, to good, since putting the cleaner through the diff.
It's well over a yr now, so still happy with the result.
Used penrite 140w oil.

can someone enlighten me on how the change of diff oil fixs this please?

[MC97GQ]

Morton,

Like everything over time you LSD oil breaks down and loses viscosity(thins out), putting in a cleaner(to get rid of all traces of old oil) and putting new thicker oil in helps with everything binding, as basically a Limited Slip Diff works on friction when pressure is applied.

A very basic answer from someone with very basic knowledge.

There are others here way smarter than me who can give a better explanation no doubt

Hope this helps a bit
