After installing brand-new CV joints I happened to notice that they looked like this after about a week of driving.
They're rusty (the original 40-year-old CVs never rusted) but more importantly is the gasket is broken and coming out. New gaskets, torqued to specs. I've had the trans out of this car on about 3-4 different occasions, so I've removed/installed CVs at least that many times on this car without ever seeing this. Any idea what is happening and how I might fix and prevent it from happening again? Thanks, |

VW type CV's (even the new stock Lobro brand with the larger 914 size balls sold for VW bug applications from Scat) dont have the groove for the gasket. use of gasket in this type of cv will cause the gasket to squeeze out and lead to false torque down of the critical bolts.
for these, use a gsasket sealer material, RTV or formagasket. if you have the groove and wish to use the gasket, apply formagasket sealer to one side (CV side) to help hold it in place during install Note some cheapo red chinese cvs are made that come with the gasket, BUT they have no CV groove, these CV's are junk (term chinese junk comes to mind), edges not deburred, and very rough race ways surfaces, very loose assembly too, kind of like a red chinese whore. also be sure to NOT reuse the lock wahsers, they are for one use only!!!! |
