I have a s1 forte v8 auto,when you go full lock and boot it[sensibly doing u turns in traffic]The diff makes a real nasty grinding,chatter noise and goes single wheeler as opposed to the lsd working normally taking off in a straight line.I was going to have a crack at the redline friction modifier when i service it soon but havent used this before,apparently its designed to stop chatter in clutch type lsd,s but being that the au is the cone type clutch i was wondering if it would do the same thing.Any ideas or does anyone use this in their lsd? oh yeah last time i serviced it i used lsd oil and penrite lsd additive 7098 but that service was done about 40000 km ago at a guess.

Hey bud, mine does this from time to time. My mechanic suggested that the next time it does it to go do figure 8s (not spinning, just idling) in an empty car park as that seems to help realign the cones. Dunno if it's BS or not, but it seems to work for me.

Thanks alot private9 ill give it a go,it would make sense if the cones are starting to embed themselves into the housing this might set them into a different position and bring back the lsd effect[a guy at a trans and diff place told me the falcon diffs embed the cones into the housing when they are about to die and when they do its time for a new diff,he did a truckload of cop cars and they all had the same problem]thanks again!

No worries at all! That noise they make though is soooo damn frustrating sounds for all the world like there's someone under the car with a jack hammer or something! Bloody aussie cars and they're dodgy LSDs!

Put one wheel on grass or dirt, and the other on the road, and floor it. Apparently, this help align the LSD clutches. Havn't had the problem, so I don't know if that is true or not.
Also, make sure you have added the LSD adative (aka, Stink)

have a read through some of these diff chatter is pretty comon in the AU LSD IRS. usally a good synthetic oil and additive will quieten them down a bit unless there is a more serious problem ''
