Got an evo 8 been driving fine .then last night there seems to be a mettalic grinding noise only when at very light throttle and seems to be around 60 mph if i put my foot down or let completly off its fine has anyone got any suggestions iv tried dipping the clutch and reving gently cant get it to do it

 

Where? Engine/transmission side, suspension, brakes, front or rear?

 

I cant really tell all i can tell is its in front of me so engine way

 

Ok. All pulleys/belts, tranny, clutch, axlles tcase or turbo. It only happens when moving?

 

Yes it only happens and on vwry light throttle only seems to get it at 60 ish + on very light throttle is like a scratching mettalic grinding noise cant hear it unless i try to do it on verry light throttle

 

Any affect on performance? Did you hit anything?

 

Doesnt seem to be any affect on performance and the car did bottom out earlier that day only lightly as its quite low but wasnt doin it straight after

 

Get the car off the ground and get the wheels spinning, with car running. Awd system might throw a fit but it's the only way I could think to start narrowing down the noise. Wish you well.

 

The transfer case in my '03 makes all sorts of loud sounds at tip in or coast. The things sounds like it is about to blow up. It has been doing this for 105K.

 

Yea, sounds like the beginnings of the tcase or rear diff making some noise.

 

U think that would be the t- case im goin to get it on the ramps and get it upto speed and have someone below listening is it safe to drive if this is the case would it only do it at light throttle above 60 if it was the t case this is gna be expensive if it is

 

The transfer cases in early USDM cars were built loose - lots of coast down noise. At stock horsepower they will last. But as the power goes up you face a rebuild. I wouldn't consider it failed until it starts howling at all speeds in all gears.

 

Any decent places to send the transfer case fo rebuild preferably in the uk if not i have gave sheptrans an email to see if they could check it for me if i sent it to them (asked for a quote )
