LSD chatter???

Hi all,

Today I drained and replaced fluid in the rear diff on the Jackaroo. I used Castrol's LSX85W140, but didn't put in any LSD additive.

Now there's an occasional deep buzzing noise that comes from the rear. It's intermitten and usually under hard acceleration just before the transmission shifts up. Can be either in a corner or a straight.

As I have never heard LSD chatter, I don't know if that is what it is and whether I should be adding the additive as per Holden's recommendations. I note a number of fellas here have put in straight LSD fluid into their Jackaroos without the additive and have had no problems.

Also, not sure whether it might be overfilled. The car was up on ramps at the time and so it wasn't level. About 3.5 litres went into the diff where the specs say capacity is 3 litres, but there was no overflow running out. I'll get under it tomorrow morning while it is on a flat and see if anything runs out when I open the filler.

Any hints on the buzz, guys?

My Rodeos manual says to use the additive. I would just use what the manual says myself.

I'll be getting a bottle tomorrow anyway.

Just a tip though, the stuff Holden sells for $30 is actually Penrite's LSD additive. About $15 anywhere else.

Geeeeeze guys I see Penrite mentioned here often - you should listen - Penrite oils will stop all your LSD Problems with their Limslip 85/140 for most vehicles and Limslip 140 for Patrols. IT IS AMAZING stuff no need for the additives - its just the best quality available. I think sometimes it gets confused with other manufacturers of lesser pedigree Why use anything else.???

Nah Bradley! Im excited -- have been since I first Put some 140 in a Patrol LSD.

Diffs dont chatter with this either.

Obviously you've never used the stuff or you'd like it too.

Oh! and I dont sell it either if that was your implication.

Nick

What can I say! Nick you're a legend.

Firstly, the problem didn't go away as originally thought, it's there everytime the car has been still for more than half an hour.

I was trying to find the LSD additive at any place but a Holden dealer and couldn't. So I popped into United Holden at Rockdale .... $77 for 30ml!!!!!!! And to top it off, they didn't have any anyway.

So I took your advice. I went up the road and bought some Penrite Limslip 85W/140 (interesting blue colour). Put it in this morning. Problem GONE!!!! And you can now feel the diff LSD'ing like it's supposed to when accelerating hard through corners.

What to do with 4L of the Castrol stuff that was in for 2 days? I'll filter it through a stocking and then put 2L of it in the front diff.

I now have Penrite HPR5 in the engine and Limslip in the back with great results at both ends. I think I'm a Penrite convert.

Thanks for the tip Nick! You saved me a stack of dough.

Its common to hear them chatter if the wrong oil is used.
I have done it plenty of times myself and driven for a few thousand ks before changing it. It didnt hurt it, as the lsd still works well, then again it was a patrol!
Maybe you should put the additive in.

It's definitely not the wrong oil. Castrol has formulated this one for Jacks and Rodeos.

I think maybe it's working its way through the components as it is a really heavy oil. I just did a return trip to the city, about 50km, and the noise seems to be gone.

even so, the nissan lsds are very choosy on which type of oil to use.
You could buy the most expensive and will still chatter.
It all depends on the right additive used in the oil.

Dont take it too hard dude, just the wording you used was very interesting.... Glad you are happy with their product.. Myself - yeah i had used penrite in the past when their philosophy was that engine oils needed to be thick - thick - thick.. wasn't really impressed... I prefer using 75-140 fully synthetic for my diffs, never a problem, even fixed a new rodeo diff that was shuddering badly. But i wont mention the maker because i do have an interest, and as we don't yet advertise on here, i don't think it is right to give too many free plugs.. Cheers
