Hello,
My 2003 Kubota L4330 Hydrostat 402 hours has begun to make a ker-chunk sound in the past day or so and I am trying to isolate the cause.
It seems to occur mainly when I am in a tight turn or have just come out of one. This afternoon I noticed I did not hear/feel it as I drove into position and made a tight right turn on level ground in 2WD. As I backed out I could hear a chunking sound as I backed straight, after exiting the turn. It would occur with less than a full rear wheel rotation, perhaps every 1/4 to 1/2 rotation.
It seems loudest on the right rear, but I thought I could also hear it coming from left rear.
I tried depressing the brake to see if that made a difference, which it did not.
The main thing that made a difference was driving it straight for perhaps 100'.
It does it going forward also, it just happens I was backing more AFTER the turn. I tred going straight after making a tight turn and it made the sound then also. I noticed once or twice it made a noticeable squeak, as if metal on meatl were occuring.
Any help in diagnosing would be appreciated.
As I am right at a service interval to change the hydraulic fluid I hope to combine both of these repairs/maintenace.
Thanks!
