No Instructions
The part itself seems like a good deal but it came with no instructions. When I called to ask about it I was told that you do not have instructions and I should go on YouTube and look for a video. It came with four clips, one being larger than the others and I do not know which column to put the big clip in?

The new transfer case rear housing shipped fast, fits well, and works good. The only thing I could think of that would make it more convenient would be to include a new gasket for the transfer case to transmission connection. I would also like to see gaskets for the fill and drain plugs. I would recommed this to anyone in need of a new housing.

Does this include the rear transfer case housing
?
Bruce L on Feb 8, 2017
BEST ANSWER: Yes, the kit includes the rear housing, the aft carrier bearing and seal, all the plugs required, as well as new key spacers for the oil pump.
Is this replacement case magnesium or aluminum?
Bryan B on Nov 28, 2017
BEST ANSWER: This is aluminum, the magnesium ones are only from GM. I suggest definitely using a pump rub kit which is a plate and not using the metal tabs.Enter an answer to this question.
does this fit the duramax also?
Samuel S on Aug 19, 2017
BEST ANSWER: This part is specific to vehicles with a particular set of options. We will need more information about your vehicle to confirm the fit. Please feel free to call our customer service department for clarification @ 888-844-3393.
Does this kit include the rear output bushing preinstalled in the case?
Rob B on Nov 30, 2017
BEST ANSWER: No, you'll have to install the front output shaft rear bearing, the rear bushing and rear output shaft seal yourself. I used a bearing drive set to install all three.
Does the transfer case need to be removed to install this kit, or can it be done in the vehicle?
Tony m on Jul 31, 2018
BEST ANSWER: You will need to remove the transfer case.
Pretty straightforward job.
Removing the two driveshafts takes no time at all.
Recommend usining a transmission jack to remove transfer case.
Two people will make this much easier.

Also, you may want a stubby 15mm wrench to get to the top bolt of the transfer case.

Hope this helps.
I have been told the chain wore a hole in my case. Any ideas why? Can I just replace the housing?
Buzz G on Jun 29, 2017
BEST ANSWER: I'm not sure. A hole developed in the upper area of mine and when I took off housing the chain was loose. You can replace the housing, which if you have a floor jack and the right tools (I learned how by watching youtube videos) you can do it within a day, time permitting.
sealant type for the housing installation?
Michele R on May 22, 2017
BEST ANSWER: I used a basic black gasket sealant in a tube along with the actual gasket itself you can get at Auto zone, advance auto or any auto parts store. Just be careful you don't tear the gasket upon putting the case back on
What tools will I need to take my transfer case out fix it and put it back in?
A-Boogie on May 1, 2018
BEST ANSWER: Standard metric wrenches and sockets will get the transfer case out of the vehicle and taken apart. When you reassemble the case you may need a tool to install the roller bearing into the case. You need to remove the crossmember and support the transmission while you handle the transfer case. The key to this job is to have access to a car lift and a transmission jack of some sort to handle the very heavy case when it is separated from the transmission. I would not want to do this job laying on my back on the garage floor.
Cost to ship to Alberta T5J?
IAIN C on Jun 6, 2017
BEST ANSWER: The shipping charge would be an additional 66.28 USD.
