Should I grease my AL-KO motorhome axles?
If grease nipples are present on the axle tube then yes.
We recommend greasing your AL-KO axles every 20,000 Km, or once a year whichever comes sooner.
Ideally jack the motorhome so both wheels are off the ground. 5-7 pumps of a hand grease gun for each side should be sufficient, until resistance is felt. Excess greasing could break the seals and fill the torsion tube.
ALKO recommend 3 greases: Shell Retinax LX (now Gadus S3 V220), Co. Kluber GL 1501 and Co. CONDA 3746 SP.
Failure to grease regularly could result in a requirement to replace the axles.
If no grease nipples are present then the axle is sealed for life and requires no greasing.
