I have failed CV joint on my Felicia ( 1.3 MPI 1998.). I also have a brand new CV joint for Favorit ( 1990.). I need information, is it possible to mount complete Favorit joint on my Felicia?

As far as I can see, only difference is shorther length of threaded part of outer shaft of the joint ( where goes main nut ).

If not, can I replace inner cage of the Favorit CV joint into Felicia CV joint cup?

Sorry for my english. I hope you understand.

You should be ok as most bits are interchangable

It's ok. I've replaced the cv joint. Only thing is, short threaded part for main nut.

Old one had 4mm washer beneath a nut. If I leave the washer and fasten the nut, it's very close to the thread end. So, I've removed the washer and fastened and secured the nut. Now, it's about 5mm thread left. I hope it will be ok.
