mods cusco clutch only

thanks heaps

 

Have you changed the fluid in it lately?

 

where is the noise coming from?

 

ya what he said

 

sound coming from the front. could it be my wheel bearings?

 

if its in the front, rule out the ayc. does it sound like a metal high pitch or a drone?

 

Not to scare you but your simptoms sound like a transfer case. If its like a whining noise and its getting worse by the day the tc is bout to go. Thats how I ended up trading in my Evo...

 

Sounds like a wheel bearing in the front.
Swerve back and forth and if it is a wheel bearing it will get louder and quiter.
The bad bearing is opossite the direction of steer that makes it louder.
In other words, swerve right and it gets louder then the left bearing is bad.

 

it sounds like a drone. checked bearings ok.. this is bad

 

How did you check bearings?
You know that modern bearings rarely exhibit play when they go bad, right?
If it is not a bearing the it is the TC. But I would double check the bearings, I know exactly what a bad bearing sounds like on the front of an evo.

 

had tha thappen to a friends evo. sounds just like he described it. i vote TC

 

managed to find the problem... thanks for the advice.. it is the tc. now i have to spend lotsa mone fixing it

 

how did you diagnose it as the TC?
