View Full Version : Driveshaft cv joint same as axle cv joint?

Does the Driveshaft cv joint use the same core as axle cv joint?
Im asking because the front side of my drive shaft is vibrating and I can ear metal on metal motion. Under the car, it's full of grease around that zone, so something went wrong.

This is the part I need to replacel; LINK (http://audis4parts.com/suspension/drivetrain/brake-parts/audi-driveshaft-cv-end-joint-kit-1982-01-4wd/)

I know it's cheap, but the shipping cost + duty tax make the replacement cost outrageous.

I have 2 front and 2 rear axle laying around here.
Are thoses cores interchangeable? (Need to know before removing all thoses parts for nothing!)

I don't think so, seeing as the CV's on the prop shaft are a bit larger than the half shafts.

If they are however interchangeable I too would like to know.

Well I'll be removing it tomorrow and packing it with new grease until I find a replacement. (Maybe a bolt snapped and it's leaking from there, and causing the vibration...)

I was so stoked to find this thread.. And then... The unthinkable happened! You never posted back on your findings :?
I am wondering the same thing. I have a really bad thud, mostly in reverse, that comes from the back of my driveline. It's not the center support bearing, tranny mount, rear diff mount. That would leave the cv in my mind. I have an axle cv sitting around with about 2k on it. Well technically I just have the inner bearing because when I dumped it the outer exploded, but it's just looking at me with puppy dog eyes. I'd rather not spend 85$+ shipping for one from jhm.
Thanks!

Also if no one knows I'll update this weekend and let you know -.-

I picked up used JHM axles from a forum member. Ironically enough, the CV joints used on them are EMPI. Not sure on the solid shaft, though.

Are you just saying jhm axles would work in the place they are meant to be aka hub to tranny/diff? What i'm trying to figure out is if, as stated by the op, will the axles cv core(splined and also the top left part in the picture he posted) be compatible with the driveline cv shaft ends.

Whoops, I was thinking the whole axle. But yeah, I have an entire JHM axle on my right side front and have the left in my garage (picked up both sides). I'll place that one in when a boot, joint or whatever takes a dump on me on the driver's side. Much easier to just swap the whole axle. When my front driver's outer cv joint fell apart on me before, I found it much easier and cheaper to just replace the whole thing. Picked up a used OEM axle for $55 shipped and it has been in there for maybe 2 years now taking hard abuse. Who knows how many miles were placed on it before that.

I think you almost understand, or you do and I can't tell you do. Thanks for the input regardless :)

The picture posted by the OP is what is on both ends of the driveline/driveshaft between the tranny and rear diff (note the boot and flange for it is different than an axle cv).
Like I said earlier, the top left part in the OP's picture is what i'm trying to transplant, or rather needing to know if it will fit the splined shaft on the driveline.

Simple terms: Can the axle cv joint replace the driveline cv joint. Minus the boot of course.

Make sense?


For future readers here's a good diagnosis guide on drivelines so you don't have to spend $650+ for a new one.

Supposedly by that guide my center support bearing is bad, but it's not torn, it does move a lot, but as much as I would expect a working one to move.

This is what all the cv's look like.

Lol I don't think Seerlah knows we're talking about the propshaft ;)

Since I'm doing Ceremonial Guard this coming Monday, I'll have enough money to go and buy a one piece propshaft! Plus all new tie rods! And Suspension! And I can get my rust spot on the door fixed!

[wrench]YAY MOOLAH[wrench]

But in all seriousness, if it does in fact interchange it'll be great!

Ok so NO the Axle CV joint and the Driveshaft CV joint do not interchange.

@vrmm, the Knock you get seem to me coming from the front support on your rear diff. Used to have that, and I fixe it with an aluminum insert. Stern Power Ring (http://www.ringer-racing.com/product.sc?productId=14)

Part number is 893521100, manufacturer GKN, costs around $80. The boot I was never able to find a part number for, but I'm sure it's made by GKN too. Advanced Automotion sells it, but I was never able to get an answer other than "just buy it from us" when I asked for part numbers. http://advancedautomotion.com/shop/product_info.php/cPath/65_71_73/products_id/48

So I spent an hour or so trying to figure out what the issue was and i'm still assuming it's the driveshaft cv's slack or me being too brutal while letting the clutch out(what I was doing on purpose in the video). I don't think the later is the issue. My noise started when I was driving to work last week/it didn't get slowly worse, it was just there all the sudden. I don't understand the higher pitched clank, like two pieces of metal hitting. Is the driveshaft hollow or is there additional metal inside?

FNK, as seen in the video I don't believe the diff mounts are an issue. It hardly moves. Am I wrong?

It may seem like I'm being really harsh and just dropping the clutch, but even slowly it does it and feels like the driveline is going through the floor while also making that noise. I'm confused as obviously the driveline doesn't twist/move in any way it shouldn't.

I also spun the driveshaft while holding the axle cv's and there was a little play that's expected when transfer power. Maybe 4 mm's of slack while all the gears switch points of pressure.

That's pretty much identical to the noise I'm getting, but mine only clinks once when going from reverse to forward. I'm 90% sure it's the rear driveshaft cv. I had it up in the air and got someone to wiggle the driveshaft while I listened and felt around, I could feel a bit of play between the driveshaft and cv itself and I could feel the clink in the cv. Tried the same with the front cv and it was solid as can be.
