Had a great time at Driffield, not such a good time on the way home, though. Overheated and broke down about 5miles from the show, had to get AA to tow caravan while we found a garage with a jet wash to blast the mud from the radiator. We were fine after that apart from the squealing wheels and broken parking brake, don't think we'll do the off road course next time :(

Least I would do is change the diff oils, and grease the propshafts....and serious consider checking the wheel bearings / regreasing and giving the brake calipier pistons a good wash .
A garden sprayer....as in pump up type are a handy tool to have if your doing offroad courses in deep mud....you can normally wash out enough mud to get you home.
[I have used 'water bottles' and pierced the cap with a knife to use as a small jet washer in the past]
