just registered and looking for a wee bit of info on a isuzu pick up that im looking at buying its a 2001 3.1 single cab pick up model TF. The steering box has a leak on it and im wondering if this is a case of changeing a lip seal or o-ring or replacing the steering box and if so how much could this cost. this is the only downfall that it has so would rather be sure of what it involves before i buy it
