I have a pretty stock '99 LC and it spends most of its time as a family hauler doing freeway driving duties. However, we do drive it sometimes off-road or in icy/snowy conditions. The rear diff housing seems to be the lowest point on the LC. My question is that how sturdy is it in relation to occasionally hitting ice chunks on the road or accidentally impacts with a large rock? For example, driving on snowy roadways at night, sometimes it is hard to see a large chunk of ice until it's too late to avoid it. I know, the best thing is to avoid that from happening in the first place, but just wondering if people have experienced damages from these types of impacts.
