I used SurTrac axles for my 240D 2 years ago. Still available today for $54.46 + $2.00 shipping on Amazon. I think I paid $57 or $58 with free shipping, so price seems stable and some local 4-wheelers have used them.

This was a 3rd car, and I recently sold it to replace with a newer wagon, but I had no problems over approx. 12,000 miles & 2 years. Doubt they will last like the originals, but they seemed well made. I put up a review on Amazon if you want more info. Don
