Product Information

A basic service kit designed to repair a pinion seal leak on E9X M3's

If your BMW's differential pinion seal is leaking it is important to address the problem as soon as possible. A leaking seal not only allows fluid to leak out of the differential but it also allows contaminants from the outside to get in.

In order to remove the seal a bunch of parts will need to be removed including the exhaust and drive shaft. Once the exhaust and drive shaft are removed from your M3 the flange can be removed from the differential and the seal can be replaced.

Please note: Before removing the nut from the flange it must be marked in order to properly realign it. We suggest using a center punch to mark both the input shaft as well as the nut. It is also advised to mark the position of the flange as well to ensure a balanced assembly. Also, vehicles before 9/2009 use special alignments for balancing. A special washer is required to balance the assembly of the drive shaft when the CV joint is bolted to the input flange. The fluid level will need to be checked after the seal is replaced. However, we highly recommend replacing the fluid in the differential with SAF-XJ + FM. We have a service kit available under p/n 33117525064KT if needed.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.

Questions & Answers

Ask a question
Question Posted by a customer
is there a socket availible for the pinion nut on a f30?
Answer (Posted by FCP Euro Products Team)
There are some differences on the drive shaft on an F30 including how the drive shaft is physically attached to the differential. There is a 50mm 6 point clamping nut that holds the drive shaft to the differential. The 12 point nut is a 65mm 12 point, p/n 83300495552. This tool is designed to be used with a Stahlwille 18x14mm drive wrench. We offer a tool from AGA that adapts to regular 1/2" drive tooling, p/n AGASTA.
Question Posted by a customer
It looks like this is only for one side of the differential. So if both sides are leaking I guess I need to kits?
Answer (Posted by FCP Euro Products Team)
This kit is for the pinion shaft seal to the driveshaft. Your vehicle will only require one. The axle output shaft seal part numbers are 33107510289 and 33111214144. I recommend purchasing this kit and the shaft seals for this job.
