DISCLAIMER: The author(s) assume that you (the reader) are reasonably capable with the automotive tools necessary to get the job accomplished, which means that you won’t glue your fingers together or use a cutting torch to get the bad part out and are smart enough to know not to try to blame or post ranting about anyone else if something goes horribly wrong ... AGREED?

TECHNICAL NOTES: The Rear Main Seal is Pictured, but NOT Needed for this DIY; I went ahead and ordered it just in case I have to change it to.

WARNINGS: There are two types of Crank Seals, PTFE (aka Teflon) and the standard Rubber Ring with a Sealing Ring Spring. If the current seal is a PTFE then you MUST Replace it with a PTFE Seal, or it will leak. Also PTFE Seals require no lubrication for installation and the crank must be clean; free of oil and grease, which includes skin oil, do not overly handle the seal prior to installation.

CAUTIONS: For Non-PTFE Seals, make note of the Crank Rotation Direction, because you must install the new seal with the correct rotation. Also you will be working under the passenger side of the car, so take the necessary precautions to prevent injury.

MISC Information: Rear Main Seal $ 38.90 (06A 103 171 A)

So let’s begin ...
