Driveshaft removal and reinstall

[digger]

I will be changing the diff and fixing a leak from rear of the gearbox. Since it involves both ends coming off may as well remove the driveshaft i think (i could do one end at a time but will check the centre support bearing to )

Is there any special markings i need to make or procedure to reinstall in the same place and retain balance? Given the diff and gearbox output flange both will be removed I'm thinking not unless i need to separate the driveshaft into two (2) for the centre support bearing and the required preload.

i don't plan on replacing the driveshaft.

No special markings needed unless you separate the driveshaft.

I generally mark the driveshaft halves just in case. Sometimes the splines will easily slip out when you "fold" the driveshaft down to get the guibo past the trans bracket and off of the centering pin of the transmission output shaft.



Speaking of the centering pin, with the driveshaft out don't forget to check the condition of the centering sleeve and make sure there is a bit of grease in the pocket so it slips on and off easily. Part number 26 11 7 526 611

Thanks, i did buy one of those and some others just incase. I may end up changing the centre support bearing as i'm not sure if its been changed
