3 Transfer Cases broken - What to do?

Cyber · Mar 23, 2009, 07:59 PM

The Evo is a Evo V RS with about 600bhp.
The first transfer case broke with normal use (the Evo has now 10 years or so).
The second one broke with the pick up of the car with the power upgraded to 600bhp.
The third transfer case broke while doing a trackday.

All of them broke in the exact same spot:

What to do in this case?
I know Sheptrans has them but I do not know if that part is upgraded.
I just want something that just doesnt brake.
Please help me out here

should give them a call and inquire about it. A built transfercase is definitely good though with 600 bhp

They have ways of making your parts stronger. Give them a call

I was having the same problem with my evo8... My car make over 650awhp, i went through 2 t-cases, then had shep build me a stage 3. Still works perfect 1 year, tons of track days later!!! He really knows these transmissions, and transfer cases.

I have a suggestion stop driving like a beast lol.. Just kidding call Shep he has some nice stuff coming out of his shop...

The preloads from the factory are all wrong for higher HP cars. I recommend Jon at TRE.. He does awesome work. Plus he may have some for sale.. Shoot him an Email.. That is the best way to contact him.. www.teamrip.com

May want to ask about or look into shotpeening or cryo- treating the gear.

awdboosted · Mar 26, 2009, 08:37 AM

I agree withShotpeening.. I don't agree with Cryo.. I think it make the gears hard and that makes them too brittle.

Thanks for all the help.
I will be going for a stage 3 ShepTrans or TeamRip T-Case.
Best regards.

Just to give you a heads up i have a evo 9 and i was up to 500whp almost 400torque when mine started whinning, yours is just broke and i sent mine to shep for the stage 3, to do the rebuild and stage 3 quaife it costed 2650.00 to be exact and its amazing some may say that cant feel much difference but i do. more aggresive feel, a very must upgrade for your power level. Tre is a good one two but very hard to contact stick with the one that is available. GOOD LUCK>

You need the bigger case bolt upgrade, This is what is most likely causing this.

its a combination of needing the clamp load of the larger bolts and also having it shimmed correctly.

Well when you get the bolt upgrade they will re shim it for the proper preload.
