Cool you found your problem.
To really appreciate what a landy can do you need to go and see an ALRC rules CCV. Landys being driven in the right manner can be awsome without difflocks or even an RTV trials event. I guarantee you that a top driver will be driving a series vehicle or have progressed from a series vehicle onto a later model. Difflocks are an easy cheat that work great and in the hands of an already good driver absolutly amazing but I would suggest you learn to drive either trials or comps before paying out for items you probably don't need. Anyone can buy their way through the mud and get the next mod difflocks, snorkels, winches, etc Put an old farmer boy vs the man in the polished 90 V8 hybrid with all the toys in a bog standard series mota with a good set of sats in an RTV who is going to be the better driver??? Perfect your skills before blowing a mortgage on your vehicle. Jai
