MF 4255 not running smoothly

ArskaFI

My MF 4255 tractor also has that banging sound when the four-wheel drive is disengaged on a hard surface. When examining it, we removed the cardan shafts and drove it in two-wheel drive. We noticed that the tractor does not roll smoothly, but sometimes something catches it and there is a rumbling sound from somewhere in the rear axle 😒. When you slowly go down a gentle hill backwards with the front wheels turned and brake, the whole tractor sways for a moment, which it has never done before. Does anyone have experience with something similar or have an idea what is broken?

Sorry for my English but I believe there are many MF experts out there who will surely understand my question and be able to advise me.

Thanks in advance

I don't know how you pasted that text into your post, but absolutely nobody will read it, because of the horizontal scrolling required.

Just paste plain text instead.

I suspect the post is from a non english speaker copying and pasting a translation of his query...

Sounds to me like you have a damaged crown and pinion or a damaged crown and pinion bearing or both.

As above. Soft axles in those

hard to understand exactly the message. but also have a 4245 and sometimes makes a banging sound when turning with 4wd engaged.. if its the same the the 4wd shaft under the tractor running from the rear to the front axel is damaged.. there is 2 shafts and the collor or shaft splines are damaged and one or both need replacing.. this damage would have resulted from wear in the front axel housing
