My baby turned 300 at last (pic heavy)

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).

Welcome to #truetraclyf Steve, they're a Good Thing.

 

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"

Yeah thanks for the heads up mate.  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

Wow what a journey this thread just took me through! Love your work mate! Keep it up 

[masda74]

Steve hasn't been on for a while. Not sure when he might come back on.

Hopefully all is well on his side of town.

[.Stripes.]

Steve and I talk regularly - he seems to be doing well, just doing his thing.

[masda74]

That is good to hear. Thanks for the update.

[discostig]

Not much news on the car front really, doing less kays now though thank god!  Think it's up around 361,000km or so 

 

Glad you enjoyed the read Simbad!  It's been a long love affair that's for sure and doesn't look like stopping any time soon.  Hopefully one day I can chuck a built engine in!

Top work, Steve! Keen to always see you updating this thread
