This might explain a strange clonk that I sometimes get from the rear of the car. I have been able to recreate the sound by reversing into driveway on full lock one way, then driving back out on full lock the other way (as if turning around to drive off in the opposite direction). It is definately not the diff because the sound certainly travels through the shell / suspension. Where abouts should I be looking for failures in the subframe?

Failures aren't in the sub frame but the chassis where the sub frame is mounted, from memory Steve Gill put up some pictures of his failure, worth looking at them.
You may be able to see a crease in the boot floor above the mount as Shimmy said or you may not, my car looked fine until the subframe was dropped but once under it you could see a crack. |

Hi,
Turners have been selling this kit for several years now. http://www.turnermotorsport.com/html..._ID=TDR4675412 Its more common in Cabrio's than Coupes but can really tear up the underside of the boot floor, once it starts. Very poor original BMW design. Shows how much 'M' cars have become pure bolt on. Regards, The Gorilla. |

Sorry Gorilla, but I don't think you are right - this NEVER happens to Cabs - as far as the US reporting is concerned it has never happened (not that I am aware of anyway) Edit - just checked the part numbers ... part 41 11 7 000 246 (item 16 above - rear axle support - Part 1 and part 16 actually refers to the same part, except 16 is the original part number and 1 is the new repaired part part number - confused yet?) is shared throughout the whole E46 chassis - be it a M or a 316i .. and even on the 4WD versions. Edit again - just figured this out ... I was right originally - this DOESN'T happen to the Cabrios - as far as I know it has never been reported on a Cab. This ONLY happens to Coupe, sedans, tourings, 4wd - not the Cabs. The Cabs had a different rear axle support floor from the get go - they were stronger!! The old production E46 chassis used rear axle support part number 41 00 7 030 266 - this was discontinued and this part was never used on the Cabrio version of the E46 chassis - the Cabrio versions always had part number 41 11 7 000 246 as its rear axle support. check the part numbers it's all there - these rear axle supports were phased in either as a repair part or quite late in the production (I believe sometime in 2006 - I have to check.)
