Ford Fiesta mk5 1.25 - Leaking gearbox after renewing drive shaft seal - managix
Hello, two weeks ago I changed my LH cv joint in the same time I replaced the drive shaft seal


But today I noticed gearbox oil after leaving my parking space. I'm pretty sure I did not replace the seal correctly, I pushed it too far or not enough idk, i'm confused, should I push the seal or not? please help me I don't want to redo this job and fail again

Thanks

Or you nicked the inner diameter surface seal when fitting.

I'd just replace the seal.

yes maybe it's nicked, did you use a socket or something else to tap the seal in ?

You should always tap it in until you hear a change in note which means it has 'homed in'. Use a socket as close in size to the seal as possible and tap it gently.
