Buzz

I have a problem with the manual gearbox of an Isuzu Trooper of 89, it has a buzz and increase the noise when the mechanic told me that it could be the anti -supply adjustment washer of the fixed train of the double, I look everywhere and I can not find that washer, the mechanic when not finding the piece I removed the teeth that had and increased the noise, that it can be, I do not know what it could be or what it may be, it may not be a synchronization. Someone who can help me !!! thank you

First it is necessary to identify if the sound is presented in a specific change 1,2,3,4. or in all. The synchronizer does not present sound only does it by placing the change but not in the march. More information is needed.

It is true the synchronisators only put noise when the march is selected, if it sounds it could always be the pro -one of cash bearings
