So I have a question for you guys about the Tamiya diffs in the 416.
I have found recently that my diffs feel pretty gritty. I am very well versed in the ways of diff builds and maintenance, but I have to say that the Tamiya diffs don't feel so great after a few runs.
What causes that gritty feeling in diffs?
I run 13.5 rubber tire inside on carpet. I use Schumacher diff grease and AE thrust grease. I am using Carbide diff balls but I have also tried ceramic as well. I sand rings with 600 grit sand paper. I break in my diff after a fresh build.
I just dont get it...when I rebuild them they feel like butter, but after only a run or two they get really bad. I know it sounds dumb, but is there a part that is usually associated with that gritty feeling in diffs.
My old Cyclone TC diffs have never felt like this after weeks of hard running. I just felt the diffs of some of my old cars that I sold to one of the locals and they still feel great.
Any ideas?
