You have one of three problems,  4th gear itself is worn, (where the hub
engages) or the main shaft bearing is moving in the case, or that bearing
was worn out and not replaced.  If the 3-4 slider hub was replaced, then the
gear should be replaced also.  If the bearing is loose in the case, than the
gear carrier needs to be replaced.  The rear housing also needs to be
checked as it holds the main bearing in place when the Trans is assembled.
If that housing shows any signs of having the bearing pound on it, it also
will need to be replaced.  Hope all this helps.
