I have a replacement FEBI boot kit for a rear axle 85 300TD W123. It also came with a new can. Is it worth replacing it as well? any DIYs that include that process?
Thanks all
EDIT: I just read this persons DIY: Changing CV Boots for your W123 Mercedes-Benz.

Im wondering now about an axle replacement. Ive been driving on a torn boot since last spring at least. I dont notice any noise however and the movement of the joint still seems OK. The other outer boot (left side) looks intact but has lost its oil. I may try a boot replacement on that one and replace the whole axle on the right side.

Is there any way to know by feel or sound (with the car jacked up already and wheels, rotors removed and axle out of the hub) if there is wear? Whats the worst that can happen with a worn CV joint if it were reassembled with a new boot?

Thanks again

As just having done this a few days ago on my own 300TD I can help you, although the posted video will probably convey it more clearly.

My method has been:
-soak a boot in close to boiling water for 5+ min
-shake excess water from boot and add the next boot to the water
-apply a small amount of gear oil to cone and spread it around
-take two small paper towel sections, one in each hand and fold a bit of the larger end of the cone around my fingers (imagine putting on nylons, that type of hold.... not that I have ever put on nylons)
-the halfshaft is already held vertically on a bench
-with your third hand put the cone on the axle
-position the boot on the top of the cone
-with one quick motion pull the boot down the cone and over the axle can

DONE.

Pledge on the cone works much better than oil. We use mountain fresh.

Also works great for beating subframe bushings and trailing arm bushings into place.

I don't think the FEBI boots will work with the cone. They are much more rigid and will probably not expand to go over the cone.

That bites. I was banking on the slip on method. I already have all the parts and cone.

they are quite rigid boots but I guess i have noting to compare them to so I wouldnt know.

Anyone else have experience with FEBI boots?

So if the cone method is good, I Imagine that would negate the need for replacing the cans?
I think I could have ordered an inner boot without the kit for almost half the price.

Anyone try the cone method with Febi Boots?
Also, is it necessary to replace the can?
Thanks

If you have Annular Axles some have said the Stock type Boots can be changed by removing the Annular End. I have had no experience with that.

Otherwise with stock Boots you need to do the below:
AXLE Boot Link cutting the CANS

Only the Astoria Flexx Boots and the similar Dorman Boots are made to be used with an Cone or the Astoria Flexx Boot expanding tool.

Oh, Thats some of the best news I heard in a while. I have annular axles it appears. I only see bolts however on the inner/differential side. My guess is that i would have to remove them from the differential in order to deal with them.

When you fill the can with oil withen 1/2 inch from the top and turn the shaft over to fill the other end, is the oil going to run out of the can into the boot?
So if that happens how does the oil get back into the can to lubricate the joint?
I have to wonder if the spinning axle will act like a centrifuge and the oil work its way beck into the can Does that make sense?
I don't see how you would be able to get your finger inside the can to pack the grease into the joint.
I am doing mine this week. So I am studying all my options here.

A couple weeks ago I installed a set of axles from a parts car. Switched sides as some have suggested. Right side inner joint came apart these were good axles that did have nasty looking cracks on the outer ridges. I did lay a bead of silicone on the top of the ridges. I wonder if I made a mistake by reversing sides.
I do have a 124K parts car. It is showing age cracks on the boots. So I am going to do them before the install.

Thanks to everyone for this thread!

Each axle joint is a sealed container = when you roll a half full coke bottle what happens to the liquid?

The joint needs approximately 50% air space for splash lubrication and cooling.

Yes that is correct, but you are turning the axle shaft upside down
to fill the other end, so then the can you had just filled runs out of the can into the boot!

Relax, you are overly concerned..

If you filled it correctly = the volume includes more than enough for proper lubrication, and will flow where it wants to be upon vehicle installation.

When installed on the vehicle the question has no useful meaning, this is an engineering - design fact that has worked on many millions of vehicles for more than 36 years in the field.

But if I remember correctly the OD of the Cone is slighly larger than the CAN on the Axle.
I got it here

I finally got around to replacing My Boots and I also used the above Astropneumatic Cone. I used the Dorman Boots and the Clamps supplied with the Boots. I also used the proper Tool for the Boot Clamps and it was under $10 from a local Auto Parts Store.
