Mixing Front Diff Fluid

Well the dealer replaced my front CV under my extended warranty but now it is losing fluid from the front CV seal. I don't know the process of changing CVs but does it require draining and adding new diff fluid? if their toyota stuff mixes with the popular mobil 1 stuff is that ok? It will only be temporary and once I get home a will drain and refill with all Mobil 1 like was prior to this incident.

 

I'd take it back if it's leaking. I wouldn't think mixing oils would cause a leak to happen

 

Yeah. Changing a CV axle is a DIY job - but it's also a fair job and quite a few people (me!) have trouble the first time they do it.

If the dealer did it and messed it up - well - I'm sure you're not looking forward to visiting them again, but it's worth your while to make sure they redo the job right.

 

Go back and get them to fix it, why drive off with something that they did an half ass job? You paid for that warranty for a reason.

 

Well it didn't appear very low when I checked it (the diff fluid). I'm currently doing a multitude of modifications (started right after dealership) and I won't be able to get the truck back there for about two weeks. I will add Mobil 1 till full. Take to shop. Bring home and immediately change to all Mobil 1. I don't trust people working on my stuff much. But hey, a whole new CV was free I trusted them enough to do that. Oh look, now it's leaking lol. Why I do stuff myself.....

 

Can anyone give me a part # as to what exactly it is that is probably leaking?

 

I'm not doing it myself. When I take It in for alignment I want to ensure they have the appropriate parts on hand to fix my cv at the same time. I will call them on it today though.

 

Ok well it's due to go in soon. Whom appears to be the "master mechanic" or "manager" at service seems relatively rude at times. They've never given me issues with warranty or repairs BUT I asked to ensure that they had whats necessary to fix the leaky CV (the seal) and as he was walking past he was just like "yea we got those".... his attitude doesn't reassure me that was the truth. Can anyone give me the part number for the passenger side CV seal going into the differential (whatever would be causing the leak)? I will call up parts instead of service to ensure its in stock
