Default What drive shaft is this in my '89 4x4 vg30e?

I'm replacing my center bearing and have the shaft out of the truck, but now I find that there is no companion flange that I can see. I also find a lock nut inside the front half of the U-joint yoke. Am I missing something or is this a different version or has my shaft been replaced with a non-OEM? I am the original owner. There are old indexing marks on the parts as if it had been serviced before. "89, King Cab, 4x4, vg30e. Thank you.

I'm not sure what you are asking.

To replace the center bearing, you take the middle u-joint out to get at the nut on the end of the front shaft. I recall using an air chisel to vibrate the old joint off. A clamshell in a shop press is the proper way. Or a clamshell with a puller attachment. It's a light press fit.

Or take it to a drive line shop and ask them to make it into a one-piece shaft. I had that done years ago and kicked myself for not doing it sooner. The shop retubed it with a larger diameter, put new top-quality u-joints in it, and charged me a little over $200.


You're wondering if it needs the center bearing for some reason. It doesn't. You will love a one-piece shaft. It's one of the best upgrades to the 4x4 HB ever.


Oh, and the mount for the center support bearing can stay there. The shaft will never hit it.

You could do the cheap trail fix like Res did and stuff a garden hose in there for a bit....

Spicer is an OEM provider, I just never seen strap style u joints on a Nissan before. Not impossible, just nothing I have seen before. Remove the straps holding the joint on that will give you all the room you need to remove the yoke at the carrier.

Oh yes. The rubber was shot and I was 1500 miles from home. I cut a piece of garden hose into short pieces and shoved then in between the bearing and the bracket. Took a handful of zip ties and tied them to the bracket so the inner part could slide fore and aft a bit with suspension movement.

Got me home..... and everywhere else for a year and a half. LOL


I overlooked the straps. Duh. But now that I think about it, I'm pretty sure mine had straps like that. Yours is an early model like mine.
