That can't be good-CV Joint failure
 

After replacing both Half Shafts 1200 miles ago (split boot discovered during clutch replacement). There was a wierd torque steer upon down shift that began immediately after replacemenm:sly: , but I chalked it up to single mass flywheel...but no chatter, clicking, or growling. Upon slow sharp right hand turn up a steep side road POP! :eek2: luckily no other damage, (other than someslight scraping of wheel. Ball joint is good; don't know why it happened. Any suggestions?

I would presume some sort of part failure - by chance was it OEM or aftermarket new or rebuilt?

Looks like something bound causing the CV sleeve to fracture. A similar thing happened to me when my CV boot cracked and a largeish rock got lodged in there on my old civic.

Hey - I blew my original driver's side back in May. Replaced with a "DSS" from fcpgroton (read: cheap chinese trash w/ lifetime warranty) and just broke my second of those. If you went with one of the cheapo new or remanu'd ones, I can commiserate.

Driveshaftshop.com does not list any mini applications, however I just called and they do indeed have the plans for R53 axles, "stage 2" which have 1yr warranties and are rated up to 450hp. $399 for the driver's side, it'll take them a few days to build it in-house and a few days to ship. So we'll see, but I wish I had called them back in May.

If it's an aftermarket one, it's inferior metal and/or sloppy design tolerances. I had the same exact carnage as pictured with both of my "DSS" axles, during autocross. They just shear out of the socket.

Cheap Chinese steel FTL.

what milage are you guys replacing the shafts?

It was a "new" Car-Quest First Equipment something...the blueing is actually heat treatment, I replaced the half-shafrts at 65K only because I was replacing the clutch and I had a torn boot...and a BIL in the business so I get my parts at cost. (hehe, I d ont't think you can put a cost on this cv...)the new shaft had 1200 miles on it and 500 of those miles were clutch break-in. I just got back from pressing carrier bearing into housing.

I got the same thing from fcpgroton, and blew out a cv joint in that same way just 3 weeks later.

POP goes the Driver CV Joint
 

I should have gone OEM....Just broke the other CV, normal driving about 1000 miles since right side broke...Stay away from aftermarket half shafts.
