General topics » Driveshaft splines

Some folk here are likely aware that BMW has a current campaign running on the R1200 & R1250GS to check the driveshaft for run-out & lubricate the splines, also they are fitting a moisture drain point in the rear bottom of the swinging arm.
Doubtless the GS has longer travel suspension than the RS so is more susceptible to driveshaft angles, but other than that it's no different to the RS.
It only takes an hour or so to drop the final drive & remove the driveshaft to check & lube the splines; the rear is most important but it's hardly any extra work to remove the shaft, check & lube splines at both ends.
Well worth doing.

A campaign suggets a factory ordered frecall - is that what you mean?

Are they recommending this at a specific mileage or time interval?

It's always been a bit of an issue on BMWs. The manufacturer does not include any spline lubrication in the service schedules, afaik (well in the UK anyway)
There are many cases of seized splines reported, or, when checked, splines having little or no lubrication. Unchecked worst case, this leads to extra stresses on the shaft and potential damage to the FD input shaft. The rear joint is most liable to problems and most important to check.
Lubrication with the correct spline lubricant and sealing up the rear gaiter with the correct sealing grease. Don't use any old grease, the correct spec is needed. For a competent DIYer, it's one hour's work max.
If your bike is dealer serviced, ask them to do it. Then repeat every couple of years, dependant on type of use of the bike.
