I have a few questions;


First I am doing 90000 mile service on my 2001 Duramax.


1. When draining transfer case I got only about 2 shots of fluid. It took much more atf to fill.


2. Front end was very sludgy and grey...had lots of metal on the plug.


3. Lots of oil/grease coming out of front of drivshaft spline out of tranny.


4. Is there a TSB for a single driveshaft replacement for the crewcab with the 2 driveshafts?


Not to dis dealers but I have had this truck in for FULL LOf's over 15 times.


It seems that no grease fittings have ever been greased. Transfer case has never been checked. Rear and front end have never been changed or checked!


I did the FULL LOF myself today ...I think its the first time this truck has been greased. I think its the first time the transfer case has been filled. I think its the first time the front end fluid has been drained and filled.


I put 10.5 qts of oil in crank. and filter


Over 6 qts of atf in the tranny. and both filters


Over 3 qts of atf in the transfer case. (after being drained)


At least 2 qts 80/90 gear oil in front end. (after being drained)


Couple 3 tubes of grease


Waiting for Syn 80/90 for the rear end (on order)


2 cups brake fluid


Cabin filter


at least 10 psi in front tires


5 psi in rear tires


1 can glass cleaner


5 bucks at car wash before I started


Do I need to do a rad flush?

check t-case every week or so for fluid loss from leak, even on new trucks there is more atf in there than what you said came out. Oil/grease on output shaft may be T-case rear seal leak, also front T-case seal can leak and atf goes into tranny not on ground. Hose it off good and watch for leaks. Grey diff oil is common if it is the factory fill, this is just wear, the metal particles turning oil grey. You don't really want a one piece shaft on a CCLB, balancing that chunk of steel would be a nitemare, not to mention vibrations from differing driveline angles, also it would tend to bend easier due to length and weight. Pretzeled driveshafts tend to eat the rest of the driveline in short order, this is from experience


It's more common than some think that vehicles don't get much chassis lube since most of the cars lube techs see don't have grease fittings

Three Quarts in the T-csae seems like more than the norm. As far as the Rad flush I did mine and I feel it is good maintance and worth the time.

Only 5 to wash that thing? You got a deal! http://www.dieselplace.com/forum/smileys/smiley36.gif



Dealerships cannot be trusted with these things. They have low paid
workers handling oil changes and lubes. You were probably just getting
an oil change and dipstick checks. They charged you to NOT properly
maintain your vehicle. I'm glad to see you took it on yourself Mike.
Sometimes it's the only way to get things done right and know it's
done.

Thanks for response ockgator. mac, hoot.


Ockgator...do you think its ok to have the leak or should I change the seal? As far as the driveshaft goes...I think I agree. But the replacement driveshaft looks huge and heavy duty...


Mac....DO you think I overfilled it? If so should I drain some out?


Hoot...How do I find ALL of the zerks? Is there an idiots guide that will tell me where they ALL are?

Here is your idiots guide (http://www.dieselplace.com/forum/forum_posts.asp?TID=191&PN=2)

Thanks Hoot.....good reading....good thing, because I missed a couple...
