I'm going to pull it this coming weekend, I have the original third member sitting in storage, its an open centre but for the short term I know its fine with no issues so I can stay cruising till its sorted and will give me a chance to inspect the side gears.

Ok, pulled the center out over the weekend, here is a quick vid of the sidegear movement, it still has oil in it so once cleaned I should expect more movement, the oil is clean, no metalic fleck, the center has done 2000 miles behind a facotry low powered 73 340 with 90K Miles on it and a 727.

it can be fixed but at what cost ? I assume there is no warranty left ?
 You would think the side gears would be supported with a far stronger design , I bet Brad could machine it up with a stronger design .

Im sure Brad could, the bigger issue is my location  :aussie: to send it back freight alone is damn near the cost of another, I'm liaising with the good man Cass, hopefully he can help somehow, I purchased it it Jan last year and as indicated its only done 2000 miles and has been noisy since it went in, I have been chasing uni joints pipes, shocks all sorts of things rather than this as a last resort.

I understand all too well where you are located , I am in a similar situation here in Panama , I wonder how the design  could be strengthened

I wonder if a custom bushing/spacer could be made to fix this, problem is you would have ta take it all apart to see if it's possible.  :eek4:

Maybe a cup to hold the side gear in place . we need a damaged one to take apart & see what could be done to improve it .

Ok, update time.......

first and foremost a huge shout out has to go to our man Cass of Dr Diff. As most of you know Im down here on a little island. I had arranged for a shop owner out of WA to gather a pile of upgrade gear for me including an Eaton Trutrac so as I could pack it and ship it on my next visit there so as all items were pre placed effectively. He purchased the TruTrac from Cass. So two years later after a lot of back and forth between Cass and myself chasing this noise I finially discoved the issue and let Cass know. Cass could have told me to simply go back to the guy I bought it from and good luck but he didnt. Without any pressure I simply asked Cass could he ask Eaton what can be done on my behalf. To this end Cass did and advised after a couple of weeks that Eaton were sending a new replacement unit out and that I didnt have to ship the faulty unit back (freight at my end was going to be $200 to ship it back and so on). well that was last week, Im on holidays but my work mate just sent me a message that the new one has turned up for me at work allready.

NOW, THAT IS SERVICE!!!!!!!! Thanks Cass, Thanks heaps and also thanks to Eaton. :clapping: :clapping: :clapping:

I glad Cass & Eaton stepped up & took care of you... But I'd like to know if there has been a design change to support the side gear for axial loading, or was there a isolated problem with your unit? It sounds like yours wasn't the only one.... Jousi reports having the same issue....
