You can calculate the rotational speed as:
rotational speed = rotational speed, r/min x 0.5 (D+d), in mm
And then verify selection here:
www.skf.com
My suspicion based upon that site and calculation is that SKF LGMT2 would be the recommended product, which is a Li soap base that is 11 mm2/s or 11 cSt base oil viscosity.
Pennzoil 707L is a classic good grease. It would have been my recommendation. Others swear by Redline CV-2.
Id recommend Mercedes wheel bearing grease 002989005110, applied by mass, then set correctly by the FSM spec.
Delo ESP EP also meets the MB 265.1 spec and would be a good option (verify youre getting the right one, there are a lot of variants).
For my Dodge Ram, Im going to try Schaeffer's 219, which has an incredible four ball wear test result, is good for wet conditions (not necessarily an issue here), and seems like overall great stuff.
So I guess Id say get the tube of MB grease if you want just enough and no extra... Get the 219 if you want a new top end grease that you can also use elsewhere.
