How Often Do You Check Fluid Levels?

The wheel nut thing.................. I had a very embarrassing night drive off road in my Defender last year, new Zu alloys with MTRs fitted drove all day Friday, all day Saturday covering about 110 miles of on and off rad in Argyll. Driving down a very rough and tricky section of terrain I had to stop, then I hear on the CB that somebody as just had a nice alloy wheel roll passed their car.............. Somebody needs to check they haven't lost one........... With which my Defender settled down on it rear near axle in the mud. All 5 wheel nuts had worked undone with te vibration. I had my wheel and no punctures to the tyre but had lost 5 special wheel nuts along the track. Just as well LR use 5 nuts on each hub as somebody else jacked the car up with a Hi Lift farm jack and I put the wheel on while somebody else with a cordless torque drill and wheel nut fitting removed one nut from the 3 remain wheels and one from the spare on the back door and I was able to very carefully drive 90 miles home without a flat bed truck to assist. So yes now I check wheel nuts religiously when I do the other weekly checks - I even invested in a torque wrench and a suitably powerful battery powered drill with torque setting and a wheel nut fitting as well as a Hi-Lift jack. Strange, I've never found a loose wheel but since! It was a good job it all happened at 5mph off road and not at 60mph on the road!

Probably needs four or five attempts to be comfortable what the level is!
