Installing New Seals in the Engine, Transmission or Rear End

Care must be exercised to prevent damage or premature failure

Oil leaks in old cars unfortunately come with the territory. After 18 - 20 years rubber and plastic just start to fail regardless of mileage. The most common leaks occur at the engine front crank seal, the engine rear seal, the transmission input and output shaft seals, and the rear end seals. The best solution is to replace them yourself. You can save hundreds of $$$ and you can be certain the job gets done right.
