Pulled the axles and the CVs were dry as a bone and even rusty.

I went ahead and ordered the GoWesty axles. I don’t want to order German CVs to find out they won’t work on possibly Chinese axles.
After I disassemble the old ones to see WTF went on I can check to see if the axles are VW units, if so I’ll hang on to them in case the replacements fail down the road.
I just want to make sure in our next long trip we don’t have issues with then CVS.
I’ll post any updates for future reference.

I've always been able to stretch the boot enough to slip a quarter inch irrigation hose in there. The end of the hose is cut at an angle to make it easier to get in. After that any small plunger will do. I've used one made for basting meat but drugstores sells this for giving babies medicine and it works fine.

Various parts places may list all years as the same but 80-82 CV axles were a little longer than later year watercooled axles.
Starting with 83 watercooled models the trans/engine was moved back and the axles were shortened.
(83 aircooled used 80-82 longer axles)

When I first bought my van I had a CV failure. Bought a set of 944 chinese knock offs axles from big box auto parts store. Continued to have cv problem's. This last winter I measure those against the original VW ones that I had saved and they where 2.5mm shorter than the VW ones. Replaced the the autoparts store CV's with T3 high angle units and put them on the original VW axles and all is good so far. Moral of story is check the lengths. Not all parts are created equal and it's hard to know what's been change over the years.

Most certainly can't assume good boots equals adequately lubricated.
in fact there was a thread here once about the Rockford boots allowing water to get in from the small end on the downward side.. it'd collect on the shaft and wick down into the joint.

I've had to grab one of these from a $dollar store and give the joints a shot of motoroil.
this adequately (in my case) lubed and stopped the clacking till I was back home and could service them properly.

I do still carry it as an emergency aid in my spares/emergency kit.


if you have a 'larger' lift then you likely would need to upgrade to Porsche 944/THING CV joints.
added lift equals shorter maintenence intervals..

Clacking suggests dry.
It can break your cages then you’re ‘done’ (towtruck).

Long needles are hard to find.
With a short sharp needle, you can poke a boot in the flat pleat.
The hole self-seals and theres’s no stress in the flat.

The Chinese axles have a different (custom) spline pattern, so you can't reuse Chinese axles with German joints (or vice versa).
This is the main reason to never throw out original German axles!
I don't know of anyone who's actually snapped a Chinese axle, but I do know the joints wear out (I currently have two, very worn out ones- getting replaced with German ones tomorrow).

I have had success running tens of thousands of miles with stock CVs and a 1.5'' lift. Remember 1.5'' lift springs really only take you to the height of a stock '85 weekender..... and they all had the same axles and joints.
Now if your axle assemblies already have 150,000 miles on them then you lift it.... ya, they're going to fail in short order, but they were destined to do that anyways. I personally have not seen unreasonable failures from stock axles on a modest 1-1.5'' lift.

They are likely correct, I was mostly mentioning the axle length difference so that you don't swap them from side to side.
The higher articulation CVS should be run with a lift. What do you have?
If your CV grease is still in good shape then you need to remove the CV, clean them and inspect for damage.
