These are certainly not all the seals on the Toyota Land Cruiser FJ60. This list is to educate novice buyers and give them confidence to locate typical problematic areas when purchasing an FJ60. The 5 listed below are for the 1981-1987 models.
#1 The Oil Pan Seal. Keep in mind that you will most likely have to take a sledgehammer to the oil pan in order to pry it loose.
#2 The Transfer Case Seal.
#3 The Head Gasket Seal. This is the easiest to spot when purchasing a truck. When this goes bad you will notice a thick black sludge start to build right above the spark plugs.
#4 Gear Box Seal. In my experience the trucks with 200k plus mileage need this replaced.
#5 The Rear Main Seal. This is the most time consuming and expensive job for a mechanic.
