Failure of Rear Trailing Arms 2005 987S

Recommended Posts

Have been complaining to my dealer for 6 months about thumping noise behind both driver and passenger (since 12,000 miles), when car was cold (in winter) only over small bumps, not big ones. Various techs at dealer drove car and said no noise. This week I took out head tech at dealer because of tire balancing issue (actually bad Michelin PS2 tire from Tire Rack--replaced within 24 hr.) but he heard noise and said it was from a bad bushing on the inboard connection of the rear trailing arms--said he had just fixed this in a 986. Both trailing arms (987-331-043-02) replaced under warranty--and noise is gone! Now happy, but have been trying to get rid of this annoying noise for 6 months!!!

I have a noise when cold coming from behind but it sounds strange like I just ran over a slurpee cup or something and mostly when shifting up. Can you please describe your noise?
