discostig Manual mode ________________________ All day, erryday Donating Members 13,798 Member For: 17y 1m 1d Gender: Male Location: Probably above atmospheric pressure Posted 09/07/17 02:34 AM Author Share Posted 09/07/17 02:34 AM So this was the count on the odo around the time I finally did this to the stock LSD so I took it to Driveshaft Balancing Services in Malaga who did this for me I'd actually managed to break off three teeth that were happily sitting in the bottom of the diff housing Thankfully the original crown and pinion were still fine So Driveshaft Balancing Services got me back on the road after only a single day (cheers Blake and Wayne) and it's driving great again, there's actually less clunks now since the old diff was pretty flogged out. Early downshifting from 3rd to 2nd (with a bit of a rev match allowed by the ZF) was flawlessly smooth, a real pleasure after having it clunk. That could also be the worn out uni joint they replaced at the same time though. The diff is quiet when cruising along at all speeds too which is great, no whining. I wouldn't know it was aftermarket. It can clunk going to drive/reverse when parked up but that's small fry. Performance wise I'm yet to give it any real sh*t but I'm sure the Eaton "Detroit Trutrac" should be up to the task. Interesting fact, this model with the helical gears need both wheels in contact with the ground to work, otherwise the wheel in the air gets all the torque. Only an issue if you are racing around corners enough to lift the outside wheel though, which I've never done. A big advantage and part of my decision was also the idea that I cannot wear it out unlike the factory clutch based LSD. I don't know much about diffs and as I found out when looking at options the Truetrac is just solid helical gears. Diff oil changes are now just recommended to be 80w90 mineral based - no LSD friction modifier additive any more either (that is actually detrimental to this LSD's performance).

One thing I noticed with the truetrac is how quickly the rear end snaps back into line when you're good and sideways. Not hard to get used to, but if you're not expecting it, oppy lock can quickly turn into "Oh cock" Link to comment Share on other sites More sharing options...

I've read that the behaviour will have changed, I'm yet to experience the conditions but have it in the back of my mind...will need to look out for it. So far just solid traction Link to comment Share on other sites More sharing options...
