Hey everyone,

There seems to be a lot of info on replacement aftermarket driveshafts utilizing double cardan joints, however there is exceedingly little review information concerning the Coast driveshafts using the OEM Rzeppa style.

My jeep is a 4 door Rubicon automatic with a
2.5" Teraflex lift. I really don't feel like buying adjustable UCAs for such a small lift (I like the way my Jeep drives), nor do I want the more sensitive nature of DC shafts concerning vibes. (I really am not trying to turn this thread into a which is better debate).

So, does anyone have any real world information on the OEM style Coast shafts? I know they use sealed Spicer joints so greasing them is out, but honestly that sounds good for me. I'll replace the shaft again down the line if it calls for it.

I searched but the info on these shafts is so scant I thought I'd ask myself, others must be wondering the same thing i'd imagine.

 

Bumping.

 

Someone MUST have some good info on the Rzeppa Coast shafts. Despite the bad press by the DC crowd, they seem perfectly suitable for low height lifts and have better resistance to the pinion margins for vibration possibility.

I would really like to hear from some of the users of this shaft.

Also, does Northridge still sell this style? Was kind of hard to tell.

 

I just ordered my Coast DC from Northridge. Mine shipped directly from Coast. So I would call NR4x4 and I am sure they could get you the Rzeppa one. Also, call NR4x4 and see what they suggest/recommend. They are good people up there!

 

Coast has a Rzeppa style shaft???

I should clarify as my post is somewhat misleading.

Doesn't Coast sell a shaft that utilizes some sort of flange adapter to mount to the existing Rzeppa that stock shaft utilizes? This would be in contrast to replacing the yokes completely.

 

They have a driveshaft that bolts to the factory flanges. Which I dont recommend.

Right. We've gotten that before, however the point should not be missed there are several cons of a double Cardin style shaft too that people often tend to downplay. The point I'm trying to make here is that given the application, the Rzeppa adapted shaft might be perfectly fine. I know vibration is vibration, but not many tales of exploded transfer cases using Rzeppas. Again, the point of this thread is to get reviews from the actual users of this type of shaft, not to just dismiss it entirely. We're talking about small lifts here where a DC type joint + adjustable uppers are not as potentially needed.

So, does anyone use it? What are your actual experiences?

 

I think you are confused about it, or maybe I am. It doesn't keep the actual Rzeppa joints just the flanges which mount on the pinion shafts. The actual joints are discarded with the shafts and replaces by DC. I believe they are not recommended because it makes the drive-shaft shorter that it would be if you used a shaft with yoke with on the pinion shafts.

 

Hey Mr Dave is this too much splines showing? Sorry about doing a semi- hijack
