Well, I Broke Her - BMW Forum

Tore the driver's side subframe mount. Auto predicted it. It's not as bad as it could be however. The mount is still intact but has torn in one spot half an inch. I got the plates on the way and will be taking the car apart soon hopefully.

I'll get some pictures up tomorrow.

Happy new year and drive safe everyone.

Damn, that sucks man

What exactly is the drivers side subframe mount?

Team Perfect Line · 01-03-2005, 02:59 AM

I believe it is the bar that connects the subframe to the axel. And in his case his broke on the drivers side. The mounts are the joints of the stabilizer bar?

No, that's not right. I believe Kevin is talking about the rear sub-frame. The rear sub-frame mounts are the carrier mounts which hold the rear differential to the chassis. When you start to get cracks around the mount/sub-frame, there is risk of the mount seperating from the chassis causing the rear diff to drop off from the rest of the car. A noticeable sign of sub-frame failure is loud clunking noise while shifting. The clunk is the differential moving and hitting against the chassis when you shift.

You did not say, "Bry" at the end of your post. May I take a screenshot :wink:

Thanks for the correction.

Kevin,

Don't let it get too bad. Even if you weld in new plates, the less cracks you have the better. A 1" crack around the mount doen't sound too bad. When mine cracked it was cracked 3/4 around the entire mount. The day I brought it in to get it fixed, the mount had completely seperated from the chassis, I could see the bolt exposed that was holding the diff!

Anyways, get us some pics and update us as you get it fixed. Get it fixed soon and drive safe!

Hey Autotechnica- You had rear sub-frame failure on a 94? Didn't your year have the plates welded in by the factory? And it still broke?

bigred318 · 01-03-2005, 10:14 AM

Nah, I owned a '92 318i before my current '94. My '92 rear sub-frame cracked. I actually totalled the car in the rain the same day my mechanic repaired the sub-frame. I wasn't used to the handling and in a low speed corner, I suddenly had some snap oversteer and drifted it into a curb... then a pole... then a tree... not pretty. The rear end gets significantly stiffer after you install the plates. I'm not even sure if was repaired properly. I was using a close ratio 4.44 diff at the time w/ pretty worn out Yoko tires which actually suck in the rain

Here are some pretty pictures to go with that story (sorry for changing the topic Kev). The x-brace and front M3 bumper survived suprizingly. I bent 3 of the 4 rims which is a shame. I'd take those ATS wheels over my current ACS ones in a heartbeat. They were stock rims on the Mercedes 190E EVOIII.
