03 envoy cv joint leaking

[dancam]

i got a 2003 gmc envoy SLT my driverside front cv joint looks like it is leaking is there a seal bettween the cv joint and the transfer case or do i have to just replace the cv joint and if so how hard would it be to replace both or just the seal or just the cv joint

If it is leaking transfer case fluid than it is the seal in the case.

[dancam]

if i contunie to drive will the the wheel fall off or seize up on me
or will it cause any other damage to the case or cv joint

Only issue is keeping the ft diff case full.

Thanks for all your help that was helpful

Just to correct the terminology:

The front CV shafts connect the wheels to the front differential, not the transfer case. The transfer case accepts the output shaft from the transmission and splits it to the forward and rear differentials.

It sounds as if you are leaking lube oil from the front differential. I am clarifying this in case you ask someone to check the fluid level of the wrong component by accident.

You can just replace the seal from the CV joint to the front diff, though a number of pieces have to come off first. Not topping the fluid level off will eventually let the front diff go dry, causing wear, overheating, and eventual failure. Depending on how much you are losing, I'd suggest having it replaced soon...it's easy to forget about.
