If my old axles had the bolt-on inner joints, I might have been able to replace the cracked boots, but the axles on my '82 240D had all the joints sealed inside the crimped-on cans. After an unsuccessfull attempt to reboot them, using the tranny-funnel method, I found none of my local autoparts chains had replacement axles availble, though a local import place did have new Chinese ones in stock for $110. However, after a bad experience with a replacement Chinese flexdisc, and reading about noisy, ill-fitting, Chinese axles on another posting here, and not wanting to do this job multiple times, I decided on the CVJ-Denver rebuilts for about $50 more apiece.
So far, after over a month, they've been working perfectly.

Happy Motoring, Mark
