Grinding noise
HI all, my 95 wrx ra has developed a grinding noise coming from the transmission. It started off sounding rotational but now is more a constant grinding, it developed very quickly in the space of about 3 miles and it gets louder with speed.
So after getting it recovered home i jacked it up and checked all the usual i.e driveshafts, wheel bearings and so on but the sound was coming from the back of the box. So i got googling and searching on here and it looked like it was either the center diff or the transfer case bearing but after stripping it all down they both seem fine i.e spinning freely and running smooth.
Any suggestions are welcome
Thanks

I've now taken the tranfer case off so i could look deeper into the box and have found the gold ring at the end of the main shaft(5th gear syncro i think?) is very loose.
Are the syncros if thats what it is meant to be loose while not under load? or is this what is causing the grinding noise?

Gonna need to see or hear or inspect that.Transmission noises are always tricky to diagnose and it could even be the rear diff.

Thanks for the reply, like i say i've been underneath as somebody has gone up through the box and the grating/grinding was deffo coming from the center diff of the back end of the box. Is there anything you cansuggest looking at as the car is now disabled and can't be moved.
