I have just started getting a knocking, rotational noise from my 96 Fourtrak, when 3rd is engaged. All gears engage easily (including 3rd), the knocking does not happen in any other gear, or when 4WD is engaged. It only knocks when under load (not with clutch in).
I use the trak regularly for towing and I'm pretty sure the gearbox is going to give out pretty soon.
Is this a common problem, and is there an easy or more importantly a cheap fix?
If I need a replacement gear box, can anyone recommend a good supplier of recon gearboxes in the southeast?
