Hi, Thanks for the infor. Location: Wellington City.

Hi, Today I noticed a minor oil leak on the rear axle, right handside. Vehicle is Toyota 60's series, Landcruiser 1984, done 306000 km 1. It is still safe for me to drive my truck. 2. What is generally the cause of this oil leak, bad seal inside axle?? 3. It is going to be expensive to have it fix?
