My friend has a TT with a worm gear rear end. What weight of greaze do you all recamend?
Best to use something like 75/140 or 80 in the wintertime if it freezes where you live.
Try this, much fun discussion in other threads too. I just use the 600w but you can play the "or equal" game to find something on the shelf near you.
The poster is asking about grease not oil, grease comes in numbers (weights) 00,0,1,1.5,2,3,4. I would recommend either 0,1, or 1.5.
Lol, as he was asking about greaze which may be intentional or not. Not sure grease was intended to be in those rear ends, but I suppose the semi fluid grease could be an or equal given what he will do with the rear end. Hope all gets solved. TS
I grew up with my Daddy and Granddaddy calling it "Grease", but they were referring to the "Oil" that is in a differential. Also heard it called "Dope", but that means a couple of other things, too.
T Ford differentials left the factory with #2 grease, the differential housings were never designed to retain oil as there were no oil seals available or installed. All the felt and seal arrangements are aftermarket assemblies for oil, and they still leak. Some members will claim they never had a problem with differential oil and there are just as many that have had problems. I do feel that #2 is too heavy and prefer #0, 1, or 1.5. A good quality non-flowing grease will lubricate a Ford differential adequately and will not flow out the axle housings. Too heavy of grease will only cut a swath and not lubricate properly, however a good quality #0, 1 or 1.5 will.
I do not recommend using gear oil/grease that contains sulfur which will attack the Bronze worm gear in TT differential housings. I am presently using John Deer Corn Head grease in my 2 cylinder REO transmission which has Bronze triple gears. Take a look at the U-tube about Corn Head Grease.
I didn't know the tt rear came grease only and the felt was not there either. Most of the manuals show the felt from what I have. Having 3 of them laying around I just assumed the felt and 600wt was factory. Good to know.
I must correct my comment regarding the TT differential, there are factory felts on the outside of the inner bearings, but not on a car diff.
David, if I recall correctly, there are felts on the inside of the outer bearings also. They are a pain to remove and replace, at least they were for me. Dave
