Ok well my best friend has an 03 evo and doesn't understand the concept of internet forums so I'm posting here to get some help. We've been trying to figure out whats wrong with his has for the past week and can't

It all started at englishtown at the showdown. He launched hard separating the boot from the cv axle. So we replaced the axle thinking everything is good.

Now the Problem: When the car is turned hard right or left it sounds like something is hanging up and making a clunk sound. It first started only doing it while turning and is now starting to do it when driving straight from a dead stop. We've checked the front cv axles, the ball joint, the drive shaft has no play, nothing is actually catching on anything. I'm completely lost, I told him it may be something in the trans but I have never worked on an EVO before so that was a shot in the dark.

Anyone?

Raise the front of the car and turn the front wheel, one wheel should turn the opposite direction of the other when you do so. It it doesnt turn or turns the same direction, something is wrong, likely the diff. ( This is going off foggy memory ).

Well Unlike my GSX when the evo is lifted the wheeles wont move without the rear end being off the ground as well. I did jack the whole car off the ground and spun the wheels but I don't remember what direction they went. But the fact is with just the front off the ground the wheels wont spin.

Sounds like a broken front diff, which is pretty weak on the '03s. The front diff is in the t-case on EVOs, not the trans. you can upgrade it to an LSD pretty easily.

Does it feel like a slipping clutch? Or what about like a front axel pops out and you loose power to the front wheels. (Give it gas and speedometer goes up then goes back down to catch)

No, nothing like a slipping clutch and it doesn't lose power. It drives fine but the noise is pretty bad.

I think I have the same thing. Actually I think my clunk noise is coming from the rear. It starts from a dead stop or turning right. I want to check the rear diff when I change the fluid here in the next week. I'll get back to you in this thread.

See if the intermediate shaft was damaged.

(goes through the trans on the drivers side.)

I'm betting you have some T/C problems, or he damaged the intermediate shaft.

Dump the fluid in the T/C and see how much broken metal falls out with it.

Sounds good, I'll report back.

Curious.. what does this mean when it happens?

I actually changed my fluid and it was just a little almost antisieze on the plug about a finger full. Not to much.

I forget the name, but part of the axel that bolts into the block, well the bolts snapped causing the axel to pop out. More than several occasions.. Sucks during the winter cause you dont get traction and whip 360's instantly!
Reason why I asked the question is because if that's what was happening that would determine that his front diff is broken.

Well update on the EVO. We drained the Tcase fluid and found no shavings. We filled the case back with Heavy shockproof and still have this LOUD clunk/click when turning. I don't know what else to tell him. It dives fine, doesn't slip and seems to be operational.

As for the intermediate shaft, I was unable to find one on the Evo, is it not like the 2g where it has a half shaft? It seems like there is just one long axle from the passenger side and then a shorter one for the driver side.

I know I sound like a newb talking here but this is the first EVO I've worked on :rolleyes:
