+1.
The thrust bearing assembly is often overlooked on the diff. There was a time when no matter how clean, how new, how much diff lube I applied to my diffs, it still felt gritty. Found out that it was my dirty and worn out thrust bearing.
You can make your own thrust bearing with the right size steel balls and washers... I refuse to pay Tamiya $20+ for a caged thrust bearing when a DIY costs less than $2 per assembly...
