I thought logging was hard on tractors, guess I was wrong. Last week while digging into a bank of dirt something let go inside the transmission in the 4x4 part where ever that is, very hard to pin point cause sound travels through metal. My son went to the local Kubota dealer with this video, they said probably the drive shaft, yeah ok thanks for showing me your skill and ability, in truth the drive shaft should've been what let go not something inside trans case. I back the tractor up the driveway and coast down so the noise is much louder in 4 wheel drive, in 2 wheel drive there is no noise. For any (07) Kubota L3400 dt experts,,,,, whats the best guess and or where to start looking............

take the front drive shaft out and see if it still makes noise. If so, it's inside the trans. It's not that hard if you have some mechanical ability.

At the point of no return now, one gear with two missing teeth, couple bad bearings on pinion shaft, then the right side axle is bent, that was $600.00 and showed up yesterday, now waiting for the rest of parts, total cost so far $1,200.00. Hoping next week rest of parts show up and also hoping my son can remember how it all goes back together............
