CV boot repair Front outer DIY? '09 E350 wagon
I guess what I need to know is what is that band and how do I install a new one once I open, clean and put it back together?
My question is, how do I "crimp" that band around the boot at the large end? It looks and feels like a ring which comes preassembled on the boot with no ends or crimping point to crimp it like the smaller band or the bands on the outer boot. I have attached Mercedes instructions on this and it shows the guy hitting this area with a hammer and chisel type tool. Is that what they call crimping? Anyone done this?

Thanks for the help

Knocking off the outer joint using the brass drift was really not too difficult. I just put the axle in a vice, and tapped away at the inner star using a brass drift and a regular hammer. Once that was off the retaining ring is a little difficult to get off. I found the best way was to take a very small flat head screwdriver and tap the screwdriver tip underneath the ring using a small hammer, and then lift the ring up using the screwdriver and put a larger screwdriver under that to pop it off. This is not a snap ring with 2 holes in it that can be removed using a snap ring tool. It's really just a thick Metal hoop that can be pried off. The boot kit comes with a new one. Once the joint was off it was a simple matter of cleaning it up. I used mineral spirits to keep rinsing it out till it was pretty clean. The joint was then repacked with the grease provided in the boot kit and tapped back on the axle after sliding on the clamp, boot, and replacing the new clip. The only thing I'm a little bit unsure about is whether or not I got the clamps tight enough using the crimping tool. The pros must use a machine to do it because it takes a hell of a lot of force to pinch it down tight. I guess time will tell.
So this part of the job was totally worth not buying a new axle for thousand bucks, or close to it. And I suppose better than using an aftermarket axle that most people seem unhappy with. The real fun began when I noticed a tiny leak in the inner boot. That was much more difficult and I will explain that in another thread that I started about the inner boot.
HOWEVER, everyone should know that rebuilt axles for both sides are completely unavailable from MB. I spoke to 2 Mercedes dealer's, both of which said the item was on backorder and would take anywhere from 6 months - 2 years before they get any in. UNREAL. So even if I wanted Mercedes to do the job, they would be unable to because they don't have the part. Unless they do have the parts but won't sell parts for people do their own repairs. Based on the problems I had with the inner boot I now understand why they want to simply replace the axle with a rebuilt one. I was successful in finding a right side axle at FCP euro. They had 2 in the warehouse and they were genuine MB parts so I bought one for the other side. For some reason that axle was only 369 whereas the left axle was close to a grand. I don't understand why this price difference, they look very similar.
Bottom line: I think pulling the axle and replacing the outer boot is well worth it, but getting involved in the inner boot is a whole different ballgame because of the way Mercedes attached it. Now on to the right side.
