Hello,
I am new to the forums and my wife's car H3-2006 has 172,000 miles, transfer case repaired @ 92,000 miles (no GM warranty covered that) running fine until I notice a greenish fluid leak on the front driveshaft seal. I wonder:
1) How soon I need to take car of that? The car does not have any apparent noise or malfunction because the leak is minor, but is there. It is not oil from the pan oil replacement because is definitely green and with a characteristic odor.
2) It looks like is not transmission fluid either because of the color red semi-transparent (I checked the level looking at the stick from the left part close to the engine and it seems normal).
3) Where can I find a decent and comprehensive H3 2006 manual for DIY? Or what would be the first step in solving this problem?

Please forgive my ignorance if am not using the proper terms. I just learn that from the guys who where doing rotation and balance this morning and I decided to have an opinion about this before to take it to the dealer$hip.
Thank you for your help.

 

Sounds like coolant. Check your radiator and hoses for a leak and check your coolant level.

 

Thank you for your answer. I checked again and it does not look like coolant. It is definitely a kind of oily fluid green color. The coolant the car is using (Dex-Cool antifreeze and coolant) is thinner than the fluid in mention and it has a light pink color.

 

Green? Hmm check you washer fluid hoses that could be green liquid and its right next to the coolant reservoir. Good luck.

 

I had found out the differential bushing was broke and causing the differential to lay down to much against the cross member and start leaking. The green fluid was fluid from the front differential.
Solution.
1. Take the plates
2. Replace the front differential fluid 1.5L Delco 75W 90. The level was below the recommended limit (up to the fill hole).
3. Follow the procedure to fix the differential bushing with a kit (bushing and sleeve $25 + shipping) sold by third party and discussed in another forum this website.
Thankx.
OP.

 

!,,,seems like only yesterday!

 

I have a clicking noise from front as well. Driveshaft CV joint eh?
