This is job where I wish I had my old shop. Press, vise, large work bench, grinder... everything you have here. Anyone who takes the amount of time that you did to create this video -earns a "subscribe." Thank you.

Man good vid. Love seeing more Mercedes stuff on KZbin. Found you from Vito's Garage.

[@ImpalamansGarage]

Appreciate it!

[@chrisn369]

I watched this vid all the way through. I really like the warts and all - you are human like all of us and you weren't afraid to show the bits you struggled with which is so true to life. The commentary was excellent and having owned my own garage business many years ago I learned so much from you. This is the best informative vid I've had the pleasure to watch - WELL DONE & THANK YOU! Ps I liked the power press - I reckon if you're a bit handy you could make one of these!

[@mrconstable1908]

That's not required now, as there's a compressed air tool that expands the new boot sufficiently so as to fit it. The video is on KZbin.

[@ImpalamansGarage]

Those boots are especially designed for use with that tool. You cannot use that tool with thick long lasting OEM boots. Not sure what the longevity is on those thinner more elastic boots that are used with the tool but they cannot be as long lasting as the OEM part. The boots I pulled off this car were faactory from 1984 as far as I could tell.

[@sompka1]

@@ImpalamansGarage The factory boots, and these febi replacements, have metal rings in them to keep them in shape. Probably key to long lasting. You can't expand them.

[@nickonastickable]

I can't thank you enough for this video! I'm going to tackle this on my '84 300TD wagon today and it's nice to know what to expect.

[@ImpalamansGarage]

I cannot speak for your wagon but I have a 2000 W210 wagon. The rear suspension and axles are heavier built than those of the W210 sedan. My point being to expect some differences between a sedan and a comparable wagon. Good luck !

[@nickonastickable]

@@ImpalamansGarage Just got one done and it's was very similar. I used the GKN kits for both sides and I suspect those axels have another 36 years/416,000km left in them. haha! You were right though, the hydraulic suspension and gas tank placement made for some extra challenges with the dif.

[@tpb_karl]

Very nice video. Going to attempt this operation on my w123 this summer.

Hey thanks video are very knowledgeable. ..DYI .IS BEST..I priced front supp work from Mercedes dealer. 8900.dollars .CRAZY..I don't have garage nor power tools. But doing it yourself better knowledgeable. And cheaper

[@ImpalamansGarage]

It's nearly always cheaper to do it yourself, as long as you are physically able. Be careful. Working with coil springs can be dangerous.

[@doktorsteen]

Thank you for upploading this video, im doing the same on my w126c 👍

[@daveyvane9431]

Regarding the i rings. One small, two large. Did you use both large o rings? One in the can, but where the other?

[@ImpalamansGarage]

No. I only used one. Several folks have asked this question. I could honestly not figure out where the second one went. Extra maybe?

[@alvinkitzmann2134]

When cutting off the can, make sure you cut it on the crimped edge only. If you cut it on the flat side, it will cut into and ruin the race that the bearings fit into. If you cut on the tapered side, you'll have additional work cutting off the can.

[@ImpalamansGarage]

Yes I thought about where to make the cut a lot before I decided to dig in. 😉

[@dannorris4945]

Another excellent vid. I originally bought the replacement can kits for my w123 280CE axle shafts, although I eventually returned them and just went down the boot route with the pneumatic spreader. I'm currently rebuilding my front suspension. Whilst installing the balljoints using the c clamp tool and impact wrench I must say that initially it's been a bloody pain and has ended up driving in a little off centre each time after checking it loads. I did think about just driving it down on the upper body section (ie not the lower flange) in a vice using a long wrench handle. Your other vid confirms this to be a safe method and must be a lot more controllable. I can't alter the power of my impact wrench......the full power is unleashed.

[@ImpalamansGarage]

Thanks so much! The W126 offers a lot of challenge in this area. Stick with it!

[@stevesugulas9941]

Excellent work and great video! Bought 2 NAPA axles 94-0889 for my 1982 300SD W126; being 24 and13/16" compressed length and axles removed are 26 and 7/16" ; NAPA tech support called to see if these are adjustable like their manual says. Would you have any experience with an adjustable length axle? These are not OEM; Thank you from Texas for your reply. Subscribed and Thumbs up.

[@ImpalamansGarage]

The stock axles have some play in the length. They have to for suspension travel and to get them in and out of the vehicle. I'm not familiar with the Naps axles. I checked that part number on their web site and they are supposed to work. I'm curious to know how does the compressed and fully extended lengths of the Napa axles compare to your stock ones? What I can tell is that getting them in and out of the car is quite difficult and that they JUST BARELY squeeze past the slotted adjustment nut holding the rear bearings. Crow bars are needed to facilitate. 😅 One last thought. DO NOT discard the OEM axles. Those things are no longer made and they are hard to come by. I would rebuild them and use them as spares.

[@stevesugulas9941]

(My understanding is the larger band is to be removed to allow extension/adjustment of length, then reset new band. The 24.57" compressed NAPA axle compares to the removed axle at 26.43"; may know tomorrow 1-8-24 if NAPA part is that much adjustable; removed axle is a CVJ Axle reman out of Denver. Car has 500k and runs like that crazy monkey. Seat removed for K'Moe 90+ lb G Shepherd to ride properly. Will follow up on this; many Thanks from Texas. Important to maintain this car. Grateful.@@ImpalamansGarage ) UPDATE: NAPA part will not fit nor lengthen; bought reman OEM thru ebay for $880 pair incl ship and tax. CVJ can reman their reman at 4 weeks out, about same cost. Thank you for good communication.

[@siamak1]

How do you clean the inner cv joint? What kind of solvent? and how would you inspect it for any damage? Thanks.

[@ImpalamansGarage]

I used brake clean in this video but now a days I like mineral spirits. Pour mineral spirits in there and slosh it around. Pour it out and let it dry thoroughly before packing with new grease. Without completely taking it apart there is not much you can do to verify condition of the joint except for inspecting the ball bearings down inside. It they appear smooth with no scratches, marring, etc... then it's fine. Of course the action of the inner joint should mimic that of the outer.

[@siamak1]

@@ImpalamansGarage Thank you.

[@siamak1]

I noticed at the both ends of the axle where splines ends an index mark as well as paint mark . However one of the axles is Annular type ( bolt type) and no marks on it. Does the Can type axles ( Homokinetic) are indexed for whatever reason? maybe balanced or the spider joint relative rotation to inner joint?

[@davidrandall2742]

Great video, thanks. I found a 3.46:1 w123 diff to put in place of the stock 3.69 diff on my '84 240d, and I hope to get to this job as well as putting in new cv joints, rear springs, and various bushings when the insurance on the Benz runs out this year.

[@ImpalamansGarage]

Removing them from the car is a little difficult. It is a very tight fit. Also you may find it difficult to slip the new rubber boot over the can in some cases. This is why I used the wood shim.

[@daveyvane9431]

At 12:14, your axle did not have the "plastic stop buffer" on the outboard (end closest to camera)? Or did you already remove it? Then how?

[@ImpalamansGarage]

Not sure what you are referring to. Do you have the part number ?

[@daveyvane9431]

@@ImpalamansGarage there is a hard black plastic cap on the outboard shaft end. It is a male press fit

It seems to be an end stop to butt against the inner wall of the spider joint. But I do not find it on a w123 parts explosion. Sadly, I don’t have the W126 explosion 😫

You can use after market expandable boots which requires a special tool to spread the extra flexible boots around the joints. It eliminates the need to take the axle apart. However I don't think those will last as long.

Hi,Great video.Just done this myself and you were a great help. Do you think the smaller o ring on the new can provides a good seal? There's some slight movement there now that the can is fitted and crimped.The crimped joint seems to provide a very good seal though.

[@ImpalamansGarage]

As long as it seals and keeps the grease in. Give it a few weeks and keep an eye on it.

[@kevinblanchard611]

Wondering why you did not grease the spider before you put the can on? Seems like it will run dry for a while until the grease makes it's way into the gear,if at all. Nice video and work. Dreading this project with no lift

[@MrRollin111111]

@@kevinblanchard611 You keep adding grease and manipulating the joint. As you extend and compress the joint, the grease seems to get sucked into the can. I managed to get a lot of grease in.

After 2 years of contemplating, i finally did the deed.

[@ImpalamansGarage]

@@MrJohnnyblazed No. I'm not swapping them. I'm not convinced that doing so would have any benefit. The balls had no wear that I could perceive. They looked perfect. The U channels of the joint had slight discoloration where the balls rested over the years but I could perceive no physical wear. (Of course I didn't have a microscope either... lol) In my opinion, changing the direction of rotation after this long a time might, in theory, induce unwanted vibration and reduce axle life. Some things you just don't change around on a machine. I know some men that won't even change the position of a lug bolt on a tractor wheel.
