What a difference that made! It's now like a new car in quietness and handling. What is Marshall refering to by "packaged in precisely the correct amounts"? Each time I've bought that expesive super MB grease from the dealer or from Rusty, it came in a big toothpaste type tube that contained enough to repack about 2.5 wheels. No obvious way to measure each dose. Does Mercedes also sell this stuff in one dose foil packs or something? Failing that option, I guess we could measure it volumetrically with a tablespoon or some such. (It expect the density of grease is about 0.7gm/cc). Also, where is all the grease supposed to be placed? Where are these "correct copartments?" Inside each cage, between the rollers is obvious. And I know the cover cap is supposed to contain a measured amount. But is there supposed to be some placed inside the hub, between the inner and outer bearings? These details are not obvious in the shop manual.
Should not have been any problem. The 150 grams in the tube should be divided in half (for each side) then 80% of each half (60 g) into the bearings and the remaining 20% (15 g) into the cap.
Seemed perfectly simple to me. Marshall -- Marshall Booth Ph.D. Ass't Prof. (ret.) Univ of Pittsburgh School of Medicine Department of Pharmacology 1300 BST Pittsburgh PA 15261 USA [EMAIL PROTECTED]
