Limited slip diff question

[daves]

Hi,
My limo has seemed a bit sus the last few times we have been out for a fourby,when I had it up on the hoist giving it a clean my mate held one of the rear wheels and I could spin the other one with not a huge amount of force,it was a little bit harder at first but once it started spinning it spun quite freely,to me this doesnt seem right.Any help would be great.

Maybe drop the oil and check the condition of it. Nice new oil in there for a start.

Mine is the same on a hoist but the LSD works a treat on/off road.
I haven't looked into it a great deal but I believe they are a different style of LSD to most vehicles, I've read somewhere that they are a ramp-up design LSD as opposed to most vehicles which have a higher breakaway set up. Does anyone have more info on this?

thanks for your replies I droped about 500ml of diff oil and topped it up with nulon engine oil flush and will put new oil in after about 1000km's ,This is meant to clean the clutch plates,I will post the results when I have put the new oil in.It is defenately not working as good as it used to so hopefully this works.

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

Is heaps better than it was has definately made a difference still might shim to get more out of it.

Good to hear its a bit better now. Keep us informed if you go ahead with the shim. I read somewhere here that a 0.7 mm shim sold on eBay was too thick and had to be machined down a bit. I think it was nissannewby's mate......

What you described happens to lsd diffs so you can take corners. It requires a certain amout of force to be able to lock it up. Its a rather large force too. Next time you're out bush go through a bog hole get someone to watch id both wheels spin you're fine

It was ben-e-boy's mate and your correct lucas I think they had it knocked down to 0.4 with good results, the 0.7 basically locked the rear diff.
