Clicking/kaPop sound when shifting

Flex disk?

Ball or other joints?

Hanger bearing?

All three - or what?

I'm finally getting familiar enough with the car to differentiate sounds. I'm not sure this is normal.

Thanks in advance -

It's not normal.
Manual or automatic?
Is the sound associated with the shifting action, or is it related, such as part of the clutch engagement or tied to acceleration or deceleration?
Does the sound come from under the car or in the back, such as the result of a broken suspension part or the dreaded differential mount failure?
Absent any other information and assuming it's a manual transmission, my first guess would be shift linkage bushings. You can look over this article: http://www.pelicanparts.com/bmw/tech...t_Bushings.htm

Thanks for the reply and for the link.

It's a 2.8L with a manual transmission.

Reading your post I see four points for evaluation:

shifting action
clutch engagement
acceleration/deceleration
location of sound

After thinking on it I believe I can isolate each step and make notes on the source.

It will be the weekend before I can get back into it and check all that, but I'll make notes and come back to the discussion.

Thanks again -

Okay, this morning I was able to take a 25 mile ride through the country and the noise seems to emanate from behind the driver's seat.

It occurs often, but not always, when shifting.

I can hear it at times when I accelerate/decelerate.

Sounds like the rear shock mount failure. Very common. Replace them with aftermarket ones from Rogue Engineering, Ireland Engineering, or others.

Roger that.

Lacking a detailed history of this car I am gradually building a list of preventative maintenance chores based on reading at multiple sources.

Granted, mechanical conveyances do not have a mind of their own, but some of the chores are all the same prioritizing their selves.

This one just got moved to the top.
