Double Cardan Driveshaft Failure Ideas

Now to just figure out the degree and size U bolts

Most say 1 degree for every inch of lift. I did 3 degrees for a 2" lift and I havent had any issues.

 

so for my 1.5 i should go with 2 degree

 

Yeah that sounds right. But dont take my word for it, call/email Marie at Headstrong Offroad for a more specific answer. Or as @ThunderOne said, 4Crawler Offroad as another reference.

 

Would a carrier bearing drop achieve the same thing as an axle shim? I know that they effect the axle in different spots, but both succeed in bringing the driveline back toward it's stock geometry depending on how big of a shim/CB drop you did...or is doing both or one vs the other better? Or maybe they achieve two completely separate things?

I know this doesn't pertain to the regular cabs (no CB) but curious about the difference for the rest of us

 

Yes, but, it changes the angle out of the tranny. Shims dont do that.

 

Good point, I could see both being beneficial for different reasons then depending on the issue at hand

 

Idk, shims will bring it back to a stock angle up to a point. I imagine with a ton of lift a large CB drop like @zero4 could be beneficial paired with shims.

 

So I talked to the driveline shop. They had to replace the center ball, and the small shaft that is actually welded to the driveshaft that slides in to the ball. They said it was beyond toast. $275 in parts. I asked them if Axle shims would help. They said that that is what the double cardan is for. to eliminate the need for shims. They said just grease the hell out of it every oil change as they suspect that the grease is escaping quickly and eating at the shaft.

I will be picking it up Friday and they said they kept the old parts for me to look at so I will post pics when I get them.

 

Dude same style truck with same issues rn. Shoot me info on how it worked out. I need to replace my DC on my single driveshaft. Or replace the whole damn thing but don’t want to. I just want my damn DC replaced and Toyota made it impossible to just buy one.

 

I have a set of Deavers in the rear and I do not have shims. I have zero drive line vibes. I am a RC though... no carrier bearing to deal with.

Here you can see the bottom of the leaf pack sitting flat on the axle perch:
