Noise From Transfer Case Area

[GroceryHauler]

I have a 06 SRW Quad Cab 4x4 that I'm getting a growl/howl from the TC area. I've replaced the left front hub assembly and axle joint which were both bad and didn't get rid of the noise whatsoever. So now I've removed the front drive shaft and the noise is gone. I've driven the truck in 4wd with the shaft out also and no noise.

My question is, is my drive shaft the definite problem?? Could I also have a TC issue with no noise in 4wd with no drive shaft??

Have you checked the fluid level in the TC yet??

 

[GroceryHauler]

Yeah,, it's full. Along with the front and rear diff.

Check the centering yoke on the double cardin joint. Since the noise went away when you pulled the shaft that is the highest failure point as most people forget to grease it because the fitting is so hard to find.

 

[GroceryHauler]

Yup, that's what I did and got as much grease in that joint as I could. To me, it doesn't seem obviously bad. That joint does seem to have a slight "catch" in it though. Do you think that would cause my issues??

 

[lpennock]

It could. Put shafts back in if noise comes back it is time for shaft rebuild.

Just had driveline shop tear apart. We found out that the tit that the roller bearings that the carden joint run on was severely worn. Had to cut yolk off end of shaft and replace. Hopefully this takes care of my problems.

 

[lpennock]

Lack of grease does that. Not unusual failure.

 

[GroceryHauler]

Yup. And 230,000 miles doesn't help either. We'll see if this fixes my problems when I get the shaft back in. I'll reply back in a couple days. Thx.

 

[GroceryHauler]

Put rebuilt shaft back in and smooth as butter and quiet as a church mouse.

 

[lpennock]

glad to hear that.

Can I ask what a rebuild like that costs?
I' m trying to figure out if it's worth it to just buy a new, aftermarket shaft for about $375.

 

[GroceryHauler]

Mine was $288
