BMW e46 (Non-M) solid delrin rear differential carrier bushing - 33176751808
If you have ever been in your E46 or Z4 and start to put the car in gear or take off from a dead stop, you may have heard and felt a loud “bump” coming from the rear of the car. It sounds like there is something trying to escape our of the trunk of your car. Well thats a sure sign of a worn/failed rear diff bushing. If you speak in BMW part numbers, then thats 33176751808.
The e46, X3 and Z4 all have 3 diff bushings holding the differential. 2 smaller ones in the front, and one bigger rear bushing. This is for the bigger rear bushing. BMW part number 33171093565 and 33176751808. A bad or failed differential bushing should be replaced right away to avoid drivetrain damage. No to mention the thumping can get annoying very quick!

Why use delrin bushings in my e46?
Well we will start by mentioning that the e46 factory bushings we made of rubber (duh!). That means the bmw put them there because they are designed to flex and absorb energy making it a little comfy on the street and not allowing a sh** ton of noise to get in). Thats wonderful if your car is a street car, but on an all out track rat, drift car, or full out race car build you want your alignment to stay constant. Get it? Flex = the enemy. That makes Delrin the ultimate bushing for all out race vehicles. It is incredibly strong, has no flex, and low coefficient of frictiom. That means no suspension bushing deflection ( which means no geometry change). We dont recommend delrin in street-use cars because of the amount of NVH but HIGHLY-recommended for track cars. If you are looking for a compromise between delrin and rubber, then check out our poly line. We offer them in a few flavors to suit your needs from OEM+, to dual purpose street/autox/track cars. Keep in mind that Delrin will outlast your OEM rubber bushings.
