Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Driving my 99 Boxster today heard a pop sound (seemed like it came from passenger rear wheel) then made a grinding noise on each rotation of the tire a bit later it popped again and the noise stopped. Any ideas what caused this?

POST 2Original post

Rock between the dust shield and the brake disc would be my guess.

POST 3 / ORIGINAL POSTEROriginal post

Did it again today, but this time the grinding noise hasn't gone away. Maybe wheel bearing?

POST 4Original post

Oh no! It sounds like you have encountered the dreaded Boxster "Pop of Death". Much worse than an IMSB failure. If you continue to drive the car it will likely suffer a catastrophic rear wheel departure. Welcome to the forum. Post pics of your car. We all love pictures of Boxsters.

POST 5Original post

Ok... seriously. It could be several things. First you need to jack the car up and get a look/feel of the rear suspension. With the wheel off the ground and car safely supported grab on to the wheel at the 12 and 6 o'clock position and try to rock it. Does it rock? -Likely wheel bearing. Grab at the 9 and 3 o'clock and rock it. Does it rock? - Likely trailing arm (control arm) bushings Next: Check the CV shaft bushings for cracks and loss of grease. Rock the shaft around. It should be able to move in the direction of the shaft axis (smoothly with no grind) it should not have any play perpendicular to the shaft. Check the bolts that hold the shaft to the transmission (6). On occasion these come loose if not torqued. If none of that exposed a problem, remove the wheel and take a good look at the brakes for anything loose or rubbing.

POST 6Original post

Make sure the stake nut (big nut at end of the axle) is torqued properly while you are there.
