I found a fix! Using OEM parts. With a total cost of $5.78 with tax.
I replaced the stock 110mm subframe mounting bolts with an Audi/Passat bolt.
Instead of using the weak stock bolts that stretch and fail over, and over again, I used subframe connecting bolts from a 2000 Audi A4 Quattro, and torqued them to the spec in the Bentley manual of: 81 ft. lbs. + 1/4 turn.
The part number is N-908-235-01
The Audi bolt is a grade 10.8 bolt like the stock bolt, but with a much larger flange for better torque distribution and It also has a much thicker shank, so it doesn't stretch as easily. The popping, and snapping when entering and leaving my driveway are now gone! I almost love my car again. The two original bolts that I replaced are P/N
WHT-000-431A. The Audi dealership had plenty of these bolts on hand; I checked with two local dealers to make sure. Here's a few pictures comparing the stock bolt (black) with the Audi bolt (green).
Oh... The original bolt looks longer, because it has stretched. It started out the same length (M12-1.5x110mm).

when you look under your car, that big chunk of aluminum. They go there.

ok, way to get smart.
why dont you go look under there, and tell me which of the 20 or so bolts are the problem bolts.
and if im correct, its probably not even that big slab of aluminum, its the smaller control arm mounts.
thanks for being smart.

Re: FV-QR (dubsker)

You're welcome. And you're right there are many bolts under there. But I only know of 4-6 that would make a major difference. Thanks for the smart compliment.
ps. One of my subframe bolts is sheared off, i know subframe clunking.

Using the picture posted above, it's the two black bolts that I added the yellow arrows to.
Hope that helps. I might look up a replacement for the front bolts one day if I ever hear any noise in the future...

Re: If you're tired of your clunking subframe...... (.badrabbit.)

Wow, thank you so much for this post. http://****************.com/smile/emthup.gif http://****************.com/smile/emthup.gif I will get this done ASAP as I have had the clunking for about 8 months now and have taken it to the dealer 3 times to get it fixed. They tightened the bolts once, it helped for a week and then went back to clunking. They said they couldn't do anything more for the problem.
It's really embarrassing. Also, there is a huge post about this that is about 20 pages long with no fix to the problem.
