transfer box alignment

Hi, my standard rear prop shaft went recently at the front joint. I have replaced the shaft and it is working OK, but I wanted to check there is no underlying cause which might cause excessive wear on the new one. I checked the standard transfer box mounts and brackets and they seem OK. Is there any way in which the transfer box can become misaligned? ie any adjustment or any way to check it alligned correctly? To my eye it looks angled downwards, but maybe that is standard. (bog standard 2003 jimny with very light offroad use). Thanks.
