transfer case & drivetrain questions.

[yoshimitsuspeed]

The whole 5 years I have owned my car it made a horrible rattle on shifts/decel or when at the right RPM. For ever I thought it must be a heat shield of some sort but after putting in my 3" exhaust and removing the shields attached to the old one and checking the others attached to the car I couldn't find the rattle. I finally tracked it down, to my suprise it was the driveshaft vibrating on the collar coming out of the transfer case. When I wiggle the driveshaft it seems to have a little more play than I think it should.

What is wrong? Is it an adjustment or a bad bearing?

Some friends that have a shop also told me the splines on the transfer case where it mates with the trans were so worn if I romp on it too much I will likely strip it out.
They don't look too bad to me and don't seem like the first place in the drivetrain I would expect to break but I thought I would go for opinions.

Also if the bearings are worn I could rebuild the case but if the splines are going I think I would be better off getting another used one in better condition. Thoughts?

It seems the rattle has gotten a little worse but it may just be me getting paranoid. Could this turn in to a bigger problem like the transfer case seizing. Mitsubishi says it did have the recall fixed so this should be at least the second t case.

Is there any silacone or urathane I could put in the splines to tighten it up a little bit without gluing the two together. It seems It would be better anyway if there was something a little forgiving taking up the initial force.

There is also a free dyno day coming up but they only have a 2wd dyno.
Can I take off my drive shaft and dyno the front wheels or will the LSD give me trouble.
I can drive there and back (abut 5 miles each way) with the drive shaft removed right.

And while I am here one more question.
I have never fully understood how the LSD delegates front to rear power, I have heard we have a 60%-40% split 60 rear 40 front is that right. If so how does it do it.

First off just because the t-case has had the recall done doesn't mean that they put in a new one, it just meant that they could have changed the leaky seal and sent the previous owner on his merry way.

Second i would take your tranny to a reputable tranny shop and get it looked at by a professional.

Third you cant just pull your drive shaft and dyno it in fwd form you would need a viscous coupler eliminator (vce) otherwise your car would drive like the clutch is slipping. And i'm not exactly positive about the 60-40 split. I believe its 60 to the front and 40 to the rear but i may be wrong on this.

Sounds like Mitsubishi is going to be installing another free transfer case, real soon. Get to a dealer. If you have a local club, see if they have any recommendations for understanding ones.

Thanks I will have to give that a try.

I just noticed the drivtrain forum, would have been a good place for this.

I talked to a dealership and they said this had nothing to do with the recall.
What's my next step?
Could it just be a loose adjustment of some sort?
Or do I need new bearings?
Or could that shield have just gotten moved or bent far enough to cause this? It doesn't look bent.

No! DSMs have a 50:50 split. Read the manual pages posted http://www.dsmtuners.com/forums/showthread.php?t=32901

They're full of crap. And, it's not up to them: it's Federally mandated.

Looks like I just might have to drain the fluid out of that bad boy before I bring it in.
Jus to remove any doubt.
Thanks for the help defiant that cleared up many questions.
