I definitely need to do this. My buddy just did his recently and has confirmed that he does get a clunking noise etc while driving, and or turning.

Can someone make a video of the clunking noise?

I describe mine as a faint chatter, it's not loud by any means.
A buddy gave me a 4oz bottle of Amsoil Slip Lock additive.
He said it should eliminate the noise. He said the Ford LSD additive (4oz. bottle) works as well.
I'll be adding it after work today, so we'll see.

Great write up for a DIYers. I decided to send mine to TRE because I wanted the whole diff looked at and I personal don't have the knowledge of how to re-shim my diff; We all know Mitsubishi didn't set them up right from the factory, at least not for high torque applications. I'm glad I had TRE look at it because I had cracks in one of the spider gears and the front pinion and side cover bearing went bad. I would have never knew I did until Jon showed me.

I have been wanting to do this for a bit now. just a bit apprehensive as i have never taken a diff apart.
guess you gotta learn somehow!

While I never had my Evo differential apart, I've done a couple of other cars and I did them both lying on my back with the diff housing still on car. When assembling it doing it that way, you hold everything in place with one had while inserting shims and bolts with the other. Slip and you've got the works on your face. So, doing it on a work bench should be a piece of cake.

Ford lost a ton fixing this very issue on Explorers and even on the Mustang, crazy how people would complain about their limited slip diff actually working! :lol:

Had to re-shim the clutchpacks for looser clearance and "restack" them: plate-plate-plate-steel-steel-steel...made me sad having to do that to so many vehicles.

Guess I'll open mine up and change it! {thumbup}

Just ask and I can provide tips and tricks to certain steps.

Does this effect all USDM Evos 03-06??

It sounds like it. I don't think any US Evos make clunking noises while turning, stock.

I dont know about fixing the stock 8 plate, but my 12 plate is quite chattery with redline 75w-140NS. During the winter Ill use factory diaqueen as Ive heard that pretty much shuts them up.

Here's all the specs.

i will be very interested to see how this is performing as i've been eyeing the TRE diff down at the shop.

I read on the forum somewhere, that someone had the shep diff. He complained of chattering noises and shep recommend him do some figure 8s.

That slips the clutches and will allow them to get some oil in there, reducing some of the chatter. A diff additive would help as well. (friction modifier)
