Yukon 6.0 AWD - problem with viscose.

Bartek · May 26, 2017

Hi Guys,

First of all greetings from Poland.

I am writing cause I am in front of decision to buy GMC Yukon Denali 6.0 AWD but there is one issue.

During the ride is hearable that viscose is not working propperly. I mean when is connecting front wheels, is making noises.

As you may imagine in Poland is hard to find any spare parts for such vehicle, so I would like to ask you if it is possible to "lets say" cut 4WD and make it only RWD?

Or maybe you have any other idea how to fix it?

Thanks for any info.

I converted mine to 2wd, it wasnt hard at all. Most likely what you are hearing is the front differential. They are super common for making whining noises. Mine did when i bought it. Light noise like whining or howling is probably normal. Loud noise is an indicator it may need to be replaced soon. Mine had light noise when i bought it and drove fine for 1.5 years without issue. You can find replacement diffs pretty easily on ebay.

Hello to Poland
Hello Bartek....

if you want to go the 2 WD way.. you just have to remove the 2 Shafts that go from the axle spindle / wheel hub to the diff. Also you may want to remove the shaft that goes from the Transfercase to the front diff.

that should be everything. but... I think perhaps you can remove the whole front diff also ( would save a lot of weight too.

But I am not 100 % sure !! Perhaps someone else could answer this question

Greetings Juergen

Depending on the year of his truck you cannot just remove the front drive components unless you remove all of them. Meaning you cannot run the transfer case without front and rear outputs hooked up and working. Also, removing the front diffs doesnt save much weight, they are aluminum and fairly lightweight.

Thanks good to know. So I will take care of my diffs

You definitely cant just yank the CV Halfshafts and delete them since they load the bearing hub assemblies. It wouldnt take long for a bearing hub assembly to die with the halfshaft missing.

That depends on the specific hub. Mine are not like that, the axles just ride inside, they serve no function in keeping the hub together.

What year, make and model is yours? My 99 OBS Sierra, (2) 03 Tahoe LT and 05 GMG Yukon Denali all have the same general setup and that is the center of the hub is splined and there is the typical axle nut on the outside which has to be torqued to around 145 ft lbs. If you dont on these then the hub destroys itself shortly.

Sorry sir, some hubs are not designed that way. Im running an OEM Timken replacement that is for AWD, and i have the axle shafts removed. Guess what, it hasnt fallen apart. The axle DOES NOT hold the hub together, it just rides inside of it. I have detailed pics of it on this site as you aren't the first person to not understand how some hubs work.
