Rx4 diff!! Q
 

can someone tell me if the diff from a rx4 is small axle or big??? lmk

If I recall correctly (its been a lot of years) the RX4 axle was a larger diameter than the RX3's.
The RX4 diff was a easy upgade for Cosmo RX5 owners as axle sizes (not bolt patterns) were the same.

some else told me small!!!!!:scratch::scratch:

12a rx4 is 24 spline like rx3 and rx2 and s1/s2 rx7 and will swap hemi
13b rx4 is 28 spline and hemi is unique to these and the rx5
