Currently, we do not carry this part for your vehicle. We're always updating our inventory so please check back soon!

Thank you for the inquiry! There were 2 sizes offered from the factory. We would need to know the size to determine if the part will fit. Try contacting the dealer with your VIN # to find out what size bearing you have and/also ask for the OE part # so we can try to cross reference it. Please let us know if you have any additional questions.

Thank you for the inquiry. This is listed to be compatible with models that have the 35mm opening and for models with Dana Spicer 1310 or 1330 yoke. You will need to confirm if you have this size or the 40mm opening, you should be able to inquire with a local dealership or mechanic to get this information.

The first image on this listing is showing the back side. So the smoother side is facing the rear.

Thank you for your inquiry Anthony! The flat black side (main listing picture) should be installed facing away from the driveshaft.

Thank you for your inquiry. If you have the part removed from your vehicle you can simply measure it to see what size your vehicle needs. If not, you may contact a local dealership with the vehicle's 17-digit VIN to confirm the size as well. Please let us know if you have any further questions.
