Got a 2006 mf 5465 when you let your foot off the brake the front axle knocks/jolts/jumps. I guess this is when it is disengaging 4x4? Any idea what’s causing it to do this? Hoping it will just been a worn pin or bush or something !

Have a look at the collar on the 4 wheel drive shaft. Splines wear and slip round on the shaft, going down the road flat out and it can sound like a machine gun going off underneath you!!!

Now Then..
As previously mentioned, most/all tractors do this to some degree. Changing the front axle oil may help, use JD Hygard/ Morris XEP 80/90 or similar.
Jack the tractor up and make sure the front axle centre pivot bushes are in good order, any play there will make it knock on disengagement..

Recently changed the alternator on mine as it was running below voltage, after changing this the knock has gone, so I’m assuming it was something to do with whatever disengages 4wd that didn’t like running below it’s normal voltage!!!
