Weird Sound?

[rekoyl116]

doesnt matter if its in gear or neutral, my gearbox makes this almost 'watery/bubbly' grinding noise. sounds like somethings loose or worn.
it doesnt really change depending on speed or whether the clutch is disengaged, its pretty much constant.


a vague description i know, but its very difficult to explain. ill see if i can record the sound in the morning with my phone.
im thinking its the thrust bearing? i dont really know a whole lot about gearboxes

any suggestions as to what it might be? it doesnt seem like an issue, its just annoying.

If it sounds a bit like rushing water, its probably a worn bearing. My car has it, and has since i've owned it. Most likely to be the input shaft bearing. I dont launch my car and would probably want to rebuild the gearbox before doing that.

Thrust bearing will come and go with clutch in and clutch out.

Of course, check the oil level anyway.

so yeah i just looked up the consequences of a bad input shaft bearing. seems bad.
guess its gonna be time to get a new box into it soon

If you're not launching it, just leave it. I've been on mine for 5 years or so and it doesnt get any worse. Plenty of track days, but no drags.
