is there a relation between $H_n (X)$ as $\mathbb{Z}$-module and $\pi_n (X)$ as $\mathbb{Z}\pi_1 (X)$-module

Let $X$ be a finite CW-complex of $n$. We can consider $\pi_i (X)$'s as $\mathbb{Z}\pi_1 (X)$-module ($i\geq 2$). My question is that is there any direct relation between $\pi_i (X)$'s as $\mathbb{Z}\pi_1 (X)$-module and $H_i (X)$'s as $\mathbb{Z}$-module for $2\leq i\leq n$?

I know that the connection between homotopy groups and homology groups is given by the Hurewicz-Theorem. But I want a relation between $\pi_i (X)$'s as $\mathbb{Z}\pi_1 (X)$-module and $H_i (X)$'s as $\mathbb{Z}$-module particularly when they are free for $2\leq i\leq n$.
