Front Crankshaft Seal Replacement Service

What is the Front Crankshaft Seal all about?

A number of mechanisms must work together to make your vehicle move forward. One of the most important is the crankshaft, which converts rotary into linear motion; i.e., it transforms the force created by the engine's pistons moving up and down into a force that moves in a circular motion that causes a car’s wheel to turn. Enclosed in what’s called a crankcase—the largest cavity in the engine block, just below the cylinders—the crankshaft must be completely lubricated, essentially submerged in oil, to spin nearly friction-free and do its job properly.

Consequently, there are seals located at either end of the crankshaft that allow it to spin freely and keep engine oil from escaping the engine block, as well as prevent contaminants and other debris from entering and causing damage to the mechanism. Since there are two ends of the crankshaft, there are two types of seals: the front crankshaft seal and the rear crankshaft seal, also known as the front main and rear main seals.

Keep in mind:

  • Loss of oil will eventually cause serious internal engine damage.
  • Inspect the sealing surface of the crankshaft or the crankshaft pulley (depending on the engine design) for damage when replacing the crankshaft seal.
  • Oil degrades rubber components.

How it's done:

  • The vehicle is raised and supported on jack stands
  • The crankshaft damper and timing belt is removed
  • The crankshaft seal is removed and a new one installed
  • The timing belt and cover along with crankshaft damper is reinstalled
  • The engine accessory belts are installed and the vehicle is lowered off of the jack stands

Our recommendation:

One of the most important parts of your car, crankshaft seals are typically made from a durable material, such as a synthetic rubber or silicone, designed to handle the extreme pressure and temperatures as well as the caustic chemicals in your engine oil. Because they are exposed to such abuse, main seals are subject to a lot of wear and tear. And whether you are talking a front or rear main seal, replacement is the only cure when one malfunctions.

The good news is that the seals are relatively inexpensive components. The bad news is that neither is easy to replace.

Front seal: The front seal is located behind the main pulley that drives all the belts, which is, of course, always spinning. The main pulley throws any leaking oil out in a big circle. It can get thrown up on the alternator, steering pump, belts, in short anything attached to the front of the engine and cause a real mess and eventually some serious damage. Consequently, it has to be removed along with many of the components attached to the front of the block to replace the front main seal.

Rear seal: The rear crankshaft seal is placed along with the transmission; therefore, the process of replacing it requires the removal of transmission, as well as the clutch and flywheel assembly. This is a very involved job.

What common symptoms indicate you may need to replace the Front Crankshaft Seal?

  • Oil leaking from the front crank pulley.
  • Oil dripping from the bottom of the clutch housing, where the block and transmission meet.
  • Clutch slip caused by oil spraying on the clutch.

How important is this service?

Letting either crankshaft seal continue to leak can be detrimental to your vehicle’s continued operation. Besides the maladies caused by driving around with little to no oil flowing in the engine, the faulty seal will be spread oil through the engine bay and undercarriage of your car as you drive, a mess that is difficult to clean up and can be a fire hazard. Replacing is better addressed sooner than later.

Alex is great! He came and knew what he needed to do to fix our truck. He was efficient, and made every effort to complete the job the same day. I would highly recommend him, and will definitely be using him for our future services.

Ford F-150 - Pre-purchase Car Inspection - Anaheim, California
I scheduled Chris to do a pre purchase inspection on a used truck that I was considering buying.Money extremely well spent.Chris found some underlying issues with the vehicle that I was totally unaware of and could have been expensive fixes down the road. If your in the market for a used car, don not rely on just the CARFAX. Have a pre purchase inspection done. Would definitely use Chris again and recommend him as well 

Ford F-150 - Car is not starting - San Jose, California
I was a little nervous at first with having a mechanic come to our home without knowing the company or the person but as soon as Whitney came to our home he was very professional and he put me at ease. He is very knowledgeable about vehicles and knows his work he was able to find our problem and fix it without delay. I feel very confident in recommending him and the company to our friends. The rates are resonable and he is very professional. Great service and customer care from Whitney our mechanic! Thank You!!!!

Nathan

Ford F-150 - Car is not starting - Austin, Texas
Nathan came to diagnose the truck and do a ten point check. He was on time , knowledgeable and hopefully figured out it was a starter problem immediantly. I drove down for one day from Dallas to help my son with repairs . My only complaint was not with Nathan but with the company’s policy regarding having truck diagnosed then having to book and pay for yet another appointment with someone else for repairs. That’s not a very efficient way to do business. One mechanic comes out to diagnose then everything he has spent time trying to figure out is wasted because next mechanic will have to spend time doing the same thing to make repairs at yet another time. Nathan was way more than capable to do repairs so not any issue with him just with company process. I’ll update this review after the next appointment to do repairs today at 3:45. And see if Nathan’s diagnosis was correct. Of course now I’m back in Dallas and truck is still in Austin with my son. I only hope that Nathan does follow ups on his diagnoses and makes sure next mechanic follows Thru .
