I want to grease the universal joints under my 1989 250GD 461.. so the spec is Long-Life Grease - Mercedes-Benz (000-989-63-51-09)... Could I use the spec: NLGI class 2, Long-life grease... I did a search but got lost
in the minutiae...so guess MB $22 plus shipping, for I am not sure of size of container.. whatever can't be too small... let me know if there is a substitute that's not $30
