CV Boot Replacement

My apologies for opening a new post discussing the replacement of the boot, I read multiple old post. I figured instead of reviving one of them with my question, I start a new one. If anything it will reveale just how little I know.

Here it goes; I've replace these boot on many other vehicles. I have not replaced one on any of my Benz until my 1984 300D reveale a cracked boot yesterday as I was rotating the tires. I would think the spline had one of those spring clip to seperate the shaft from the actual bearing. Are the shaft on the 300D that perminant they cannot be seperated?

There is some pictures doing the Annular type axle in the following thread.

I am not sure which type of Axles you have. The below pic is of a Homokinetic type. You cannot take the Axle apart with out removing one end of those to Can Assemblies.

In order to replace the same Stock Type Boots you need pic one end of the Axle to either cut off the Can or un-crimp the Can.
Pull out the Spider and Balls and use a Hydraulic press to press of that end.
At that point you can slide Boots off and new ones on.

Reverse the procedure except you either use a new Can or if you found a way to un-crimp the old can and you need to crimp that lip over.

Or you can take the easy way out and stretch the Astoria Flexx Boots or Dorman Boots over the Cans and not have to take the Axles apart and not need a Hydraulic Press to do so.

The 84 300D could have either Homokinetic or Annular Axles. The Annular Axles Boots are easier to change.

This is a thread with pictures on how to replace the Stock Boots on a Homokinetic Axle (the one with Cans on each end) doing it very close to the Mercede Service Manual Method without the Mercedes special Tools to do the job.

The reason I am asking is, I still have the 85 a friend of mine left me. I know the shaft on it are new, I helped him install them about a year or so ago. If I can use those it should be a quick repair.

If the Axles mentioned are interchangeable they should have the same part number when you look them up at your favorite internet Parts Sellers Site.

I thought I would share with everyone my experiece with the boot replacement last night. After reviewing one of the link provided, I thought I would share one of the key point in sliding the boot over the long funnel I used.
I microwave some water until it was boiling, dunk the boot in it until it was hot to the point barely managable to handle. It made sliding it down the funnel easy and made the entire evolution painless, it took longer to bolt on the rear diff cover than installing the boot.

So, who ever suggested heating up the boot. Thank you.
