I just got my 05 EVO out of the shop for the 3rd time in 1 1/2 yrs for the same thing. I had a minor diff fluid/transmission fluid lk according to the Mitsu dealership it is the seals between the differential and the transfer case. it is the seals that stop the diff fluid from going into tran fluid. Does this sound correct? Has anyone had this same problem? Im hoping this does not happen anymore.

 

YES.. there are two o-rings on the t-case whereit mounts to the tranny... it is very common for those to fall out/or get torn and leak.. not a big deal tofix

 

I have this problem!

 

So both O rings got damaged? Could it be just one?

 

Hey guys:

If you need part #'s for any of the transfer case seals hit me up with a PM; I just ordered a set for installation of my rebuilt TC.

Unfortunately, I'm too familiar with this whole process.

 

I had this once as well.

 

doesnt matter... if you replace replace them both.. as soon as you take it off the tranny they stare you in the face.

 

So what im seeing is that it is normal. Actually how long does it take to fix. It took them about 9 hrs to do. does the trans case have to be seperated from diff? How long does it take you guys?Im sure it will be back even after the warrenty is up...oh by the way they gave me alot of crap for my bolt ons!!!!

 

So how hard is it to change these seals?

 

You'd have to remove the transfer case to replace/install the o-ring.

9 Hours seems like a lot of time too.

Good luck.

 

Well here it is 3000 miles later and it happen again (see 1st post) and the dealership voided my warrantee. so what can i excpect to pay a shop to replace these seals? please help. i dont want to get raped i all ready did by mitsubishi.

 

Labor would be around 450-600 depends on the shop.

 

Remove wheels
Unbolt suspension
Remove cotter pins & castle nuts
Pound axles through hubs with rubber mallet or air hammer
Remove axles
Remove stub axles with slap hammer
Unbolt tcase from tranny (if ACD, unbolt & tie off ACD line)
Replace seals
Repeat in reverse (if ACD, bleed ACD with key on, foot on gas for 10 seconds. refill w/ dextron iii as needed)

 

Thanks Shameless... does anyone have an idea of why this happening over and over again? it seems to be happening every 3000 miles and due to they voided my warrantee it really sucks.

 

Well finally deciding to do it myself, due to the cost of almost 1000 dollars that the sucky shops and dealerships around here want to charge me.

For all of you guys who have done this how long did it take? This will be my first attempt but pretty mechanically inclined and all the tools.
