I am 1500 miles away from my garage on a road trip, and my rear flex disc fails.

I think it died from abuse- those WOT passes at 120MPH coming into Nevada finally did it in. I was hammering pretty hard on the way down...


FYI- if u feel a very slight high speed vibration under load, or at high speed check the flex disc. Mine was doing that after I left Seattle but I chalked it up to a slightly out of balance rear tire or perhaps washboards on the road. It was that subtle.

Mine failed by Riverside, CA on the way back to Vegas @ 4PM, on a Friday afternoon. I got really lucky finding a cool shop that would even bother to talk to me that late on a friday.

By the time I pulled over thing was clunking and vibrating so badly under load I thought I was being followed by Harley riders. It seriously sounded like something dragging over the right rear tire.

I get my car back on Tuesday, gotta drive AGAIN from Vegas to SD to get it.

The moral of the story: Check the flex disc if there is any noticing of vibration under load.

Yes, yes. Was doing the differential, put in a new one. Do we have a second one near the transmission?

All German (RWD) cars suffer from this. Same story with any aged BMW.

Friday afternoon before a long weekend, from out of town, in traffic, car is trippin out bad,
thinking the worst

-Phoenix, AZ had flash floods and I was there- drove my car through 14 inches of standing water and I'm lowered.

I thought for sure it was water contamination in the differential when it started knocking and grinding that bad.

It sounded like something dragging against the tire under load, like my fenderwell came out.

nuts.

PS there are two- one in the front.

I keep wondering (I didn't look that closely) if there's a carrier bearing I thought it was one piece.

Might have that changed too while it's up in the air.
