Im getting a clunking sound when I go over bumps. I went other the car and narrowed it down to the passenger rear cv axle shaft. OEM part number is 42310-sja-003. I’m having trouble finding an aftermarket part. The dealer parts dept quoted me $900. I see front drive axles on aftermarket automotive part websites but no rears. Anyone have any experience on this?

Couldn’t figure out how to edit.
Its a 2005 RL with 144500

Any way you could have a local rebuilder work on the current axle and rebuild it?

Thank you all for the information. After reading a number of threads on this site I found was what causing my clunking/rattling sound over bumps. It was a loose e brake cable. Since their was little tension on the cable the e brake components would rattle over bumps. Their is an adjustment nut next to the
e-brake pedal a couple of turns and the problem was solved. I saved some serious dollars.
