right rear rattle with video and audio

Recommended Posts

Hi everyone,

I'm embarrassed to say that it's been a while since I've been back to these forums. My '98 Boxster has been running incredibly well until last week when I began hearing a rattle from the right rear of the car. I've done a pretty good search about rattles and soon I'll be removing the serpentine belt to see if the sound is coming from one of the pulleys or begin the sad process of hitting the heat shields with a rubber mallet. In the meantime I thought I'd post up a video / audio of the actual noise and see if someone much smarter than me can provide the proper diagnosis. The rattle sounds like a bunch of angry crickets on a hot summer night and it increases in pitch with revs but is always there. New water pump two years ago. Perhaps it's time for another?

Thanks in advance,

Hard to say for sure. As I listened to it, I thought it sounded like a pulley rattling. It seemed to be in sync with the belt frequency. Have you checked all of the pulleys to see if any are loose or damaged? Beyond that, it is difficult to say. Either a pulley or something they

are attached to (water pump, alternator, A/C compressor).

Good luck.

Wow, sounds like you need a water pump bad. Loosen the belt and spin your water pump by hand. I'll bet that its not too smooth and its got a fair amount of axial play. I'm surprised its not leaking.

Remove the belt and start the car. That is what I did when I thought I had a noisy belt or bad bearings on something back there, This will rule out the belt. Yes, you can run the engine without a belt oln.

Then play around with all the pulleys. Too much bad noise for it to be a belt I think.

Thank to all for the advice. It was the water pump. Replaced it, thermostat and belt. A surprisingly easy job.

How many miles on the waterpump?
