Hello all,

My right CV axle was repaired by a cv axle shop because the boot was torn. It is only after the fact that I have read about how much special care is required to change this axle because removing it can damage a seal between the TC and tranny. The axle shop had a 4wd VW and a Mercedes they where dealing with, so they are not neophytes, but they used a lot of force to remove that axle. How do I know if the seal is damaged? Will I see fluid on the flor or this all internally happen without me knowing?

Thanks

 

If they used a lot force, they probably did it correctly. That intermediate shaft in the TC comes out really easy. Which is kind of bad, because you don't want it to come out. Separating the axle from that shaft is an extreme sport! I beat on mine for 3 days.

I gather you won't necessarily see any fluid on the floor if the seal between tranny and TC was breached. But the TC will flood with transmission fluid, assuming you have an automatic. The TC uses regular gear oil that smells like a cross between burned sulfur and rotten onions. If there is any red transmission fluid in there, the seal was breached. If not, you're OK.

 

Thanks for your reply. So there is no way to know other than opening the TC drain plug?

 

Perhaps a dropping ATF level could be taken as an indicator.

 

Thanks for your reply. I can't really check the ATF level on this car unless I have a lift since the car has to be running and at a specific temperature range, and there is no dipstick, just a drain plug.

So there are no symptoms or external signs for me to look for? The transfer case would just eventually flood with ATF, at which point I have a transmission with low ATF and a flooded out transfer case?

 

If the seal has been breached, how long until it starts spitting out ATF from the case? Would it be right away?

Has anyone actually breached the seal changing the axle or is it just a possibility ?

Many thanks

 

I have read some posts where that seal was damaged when the intermediate shaft was pulled out too far. Have you tried the search feature? If I find one of them, I'll link to it.

 

Thanks for your reply. The archived topics I pulled are a little confusing to me:

Here it is said that typically there is no damage at all even when it's removed without care.

On another it says its safe to go out up to 7 inches.

On another it says that if great care is not taken they will surely fail .
