Strange Rattling Noise On TI

[londonti]

Hi all first time post here, i have owned my 1999 Ti for nearly 4 years now, but as of the last few months i have noticed a very strange rattling noise coming from the back of the car when driving, but it only happens when you hit a bump or speedbump etc, you cant hear it when on a good flat road, its been getting louder and louder recently and now it is driving me insane, anyone have any suggestions as i am not the most mechanically minded, or anyone encounted this problem? any help will be greatly appreciated.....

many thanks!

My guess is the rear shock mounts, its more like a clunk instead of a rattle though.

Check the bottom shock mount rubber (make sure it is intact) and make sure the bolt itself is tight (should be an 18mm bolt head). If those both check out OK, check the top mount to ensure the rubber hasn't punched through the top of the mount (requires removing the rear interior panels to access the upper shock mount). Also check to make sure that your exhaust mounts are all intact (two rubber mounts near the rear of the muffler, one in front of the rear axle).

Hi, thanks for replying and giving me some advice, took the rear panels off today and you were correct it was the top or the rear shock! Thanks

Order some aftermarket RSM's to avoid this in the future, the stock ones are prone to failure.

I believe I used Meyle HD's on my E30 with a E46 reinforcing plate on top of the shock tower. I'd gone through a few RSM's and the Meyle has held up. I have the same RSM plate for my other E36 with Sport Billy's and HR springs.

Perhaps but aftermarket ones arent that much more than that setup and they have cheap replaceable bushings instead of re-buying the whole unit.
