Replace Rear CV boot?

[kguarnotta]

I've got an '86 Syncro with Subaru motor.

The CV boots and rear axles were replaced last oct 2019 with the GoWesty Heavy Duty 930 axle kit. This was done by the PO.

The inner boot on the left side has torn open. I've ordered replacements - and am wondering - will I need to take the whole left axle off to replace, or can I just remove inner boot/axle. And replace the boot with it in place?

I don't know if this will save any time - or be so hard to manage, that I should just take the whole left axle off?

As you can probably tell - I've not done this job before, just been reading about it a lot. I just got the replacement boots - and am looking to start the job.

it needs to come off completely ,you will have to remove the joint to replace the boot, look at the others they may have rips , have a Bentley or Haynes manual ?

[kguarnotta]

ok - yeah I've got the Bentley manual - I've checked the others - they looks fine. (The other 3 rear ones).

The front ones look a little degraded, these were not replaced by the PO.

I'll plan on having to take the whole thing off - thanks.

In a pinch I bet you could leave the axle in place, but will entirely depend on
how much persuasion the joint needs to come off & get back on the axle...

Pull the axle. It's not that hard. Remove one joint and replace both boots.

I did that ( or rather had some help getting all that done).

Inner boot driver side already split - I need to get boots again - and GoWesty is out of stock.
I'm trying to figure out alternative options - when I search for 930 axle CV boots, the boots don't look right. IE they just look like a boot - but not the metal flange that actually bolts in. I'm guessing there are a few options for this, and I'm not searching correctly.

Any guidance on what part number I should be looking for?

I have to ask. Is your van lifted, how much? Guess why the factory engineers did not lift them any higher?

At Carat height, 35 years ~400000 miles boots replaced once just because.

Yes, My van is lifted. I'm not sure exactly how much - done by a previous owner. I think it is 1.5 or 2".

Wish someone had told me this when I redid my 930 CV's...

If you do remove/inspect the wheel side CV...

I rebuilt my GW 930 axles that were already installed by a PO as well, although I made a mistake as per GW instructions. From GW on their website:

"Only three circlips per axle are used to
constrain the CV joints. The transmission side
CV joint needs both an inner and an outer
circlip. The wheel side CV joint only receives a
retaining clip on the wheel side of the CV."

I installed 4 circlips/axle, still running fine today after 30k miles after replacement, but wish I had read the instructions first. Not sure what GW's intentions of leaving the wheel-inner circlip missing is (there IS a groove for it), guessing it is for the CV joint to slide on the axle during wheel articulation, although not sure this is a good thing.

Anyway, GW's instructions are on their website for 930's.

Best of luck sourcing the boots. I know their are plenty of other reputable dealers out there. I've used "kartek off road" for sourcing 930 axle parts, but have not checked their inventory as of this post.

Cheers!
Benjamin

thanks - the issue I find - when I look for 930 CV boots - I see this - https://tinyurl.com/zaxndnta

Can I just clamp this boot to the metal flange? Sorry for the stupid question, but I'm obviously confused about this.

Another example - I thought I might try FCP Euro parts, as they claim toi warranty forever - so I might save a couple bucks each time I have to do this.
I see this - https://www.fcpeuro.com/products/porsche-axle-boot-gkn-90133229312

It says it is for a 930 - but it looks very different than the gowesty one.


GoWesty sells it attached to the metal flange - so I figured that is how it is supposed to be.

Last edit - I'll call KarTek -looks like they might have a clue what I'm talking about...

As far as them cracking due to it being lifted - I think there are lots of folks seeing theirs split without there bus being lifted - see here

Not sure I understand you Dave.

Are the 930 axles something that GoWesty made, or just adapted to fit our Vans? Or did they just realize they were compatible?

thanks dave, I was wondering why they pics from any other vendor looked different.

Theoretically I could get any boot - and attach to the existing flange. I just need a clamp to hold it in place.

just an update...

I've taken the rear axles out - and it looks like one of the CV joints was not greased properly by my mechanic - or is somehow lost all it's grease. It it not looking good - and I don't think I should reuse it. I've cleaned the other three and they look and feel ok.

So I've got to get one new CV joint and boot - then repack with grease, and reinstall.

I'm trying to figure out alternatives for boots and grease as gowesty is sold old out. I spoke with KArtek - they seemed pretty knowledgeable - so after taking it all apart on Friday - I'm going to call them on Monday and get my order in.

Go Westy - suggests 2 tubs of 14 oz each should be enough to pack all the joints, and have some leftover. But on another page - they say you should only need one 14 ounce container? Any ideas on quantity of lube needed? I figure I'll pack them - but would be helpful to have some guidance as to amount I should probably use.

ok - I ended up getting a one new CV joint from KArtek - one original one was pretty bad. The other 3 seemed ok. I also got a new boot from Kartek. For future reference - this is what I got -

EMPI Porsche 930 Steel Single Axle Boot Flange For 86-9301 CV Axle Boots 3/8" Flange Lip
EMPI 86-9320 Porsche 930 Small Rubber CV Axle Boot For KTK8693020 Or KTK930SDBF Double Boot Flanges
Kartek Off-Road Polished Porsche 930 CV Joint For 28 Spline Axles With 300m Cage
Porsche 930 External Spirolox Retaining Ring For 28 Spline CV Joint Axles 1-1/8" Inside Diameter
Ideal 63mm To 85mm Diameter Narrow CV Joint Axle Boot Or Hose Clamps 5/16" Wide SAE Size 44

With these I was able to make up my own boot. The CV joint they sell is super smooth compared to the ones already on there. Supposedly Kartek polishes the CV joint. Is it worth the extra bucks? I'm not sure. I also don't know what these Gowesty CV joints felt like when new.

I see where Gowesty says to only use 3 of those spring clips, but that makes no sense to me - I used 4.

I reinstalled the driver side axle - no problems.
I got to passenger side, and I can bolt up at the wheel, but can't seem to get the axle around the flange it is to blot to at the transmission side. Somehow it came out - so it must be able to go back in...I think if I remove the rear locker, I may have enough clearance, but anyone have any suggestions, because it doesn't make sense that I should have to do that. I currently have passenger side up in the air, I wonder if that is shortening the distance to cause the interference? I'll try to lower it to the ground and see what happens...just thinking out loud here as I type...

oh yeah - I also meant to ask - why isn't there a split boot option for these CV joints? I know on my '65 they sell a split boot - I know that is a very different mechanical thing, but I don't understand why that idea could not transfer to these CV joints?
