Just finished my 1,000 mile service. Took 5 run, drain, fill, run cycles to empty the goo. Its all out. Did not use diesel or anything other than gear oil. Did run it between fills to heat the goo. Also was surprised that my compensator did not have a zerk for grease. My build date is 9/13 and chassis # is 986 I think.
And the first 20 mile drive, its as noisy now as before. Sort of let down.
