axle replacement

I have read numerous replies for the process of replacing axles from this site. However, I could not find any information to help me determine which axle my vehicle accepts. I currently own a 1981 300d.

When I look for axle replacment parts I am confronted with two choices.
1. annualr joint (excuse the spelling)
2. Homockinetic Joint.
How do I determine which is the proper one for my vehicle. It appears that the original axles are on the vehicle.

I would also appreciate any tips that individuals may have encountered so as that I might avoid the same.

thanks,

Smile welcome !

i believe that if you look at yours they are the kind that have the 'cans' on each end. then you have your choice the expensive kind (homokinetic) or the original (less expensive) type.
this is a pic of the rebuilt one i had installed with the 'can'

Pic show is a homo joint...


The later annular style has 6-8 bolts (socket headed cap screws known as "allen bolts") in around the perimeter to hold it to the differential output flange. The homo joint goes straight into the differential.
Either will work in any W115 or W123.

Very common question...

michael i think this is the one you refer to

Homokinetic joint refers to an inner C.V. joint that has an output shaft as part of the original design. Later design versions incorporate a seperate annular (or flat) inner C.V. joint with an output shaft that is bolted to it. Most models up to model year 1980 use the homokinetic style joint. 1981 and on models may have a mix of both versions. This is most prevalent in early production models in 1981.

That statement assumes the axles are orginal to the car!

I've put axles in several W123's and they were all 81+ and most had two homokinetic axles.

Steps:

Determine what axles you have in your car
Determine what your budget is going to be
Make a decision on how long you expect the axles to last before future replacement.

Then you can make a good decision on a replacement!

Thanks for the help. The pictures are great. I can finally put a name to a picture to figure it out. Looking under my car it appears that I have the homokenitic axles.

In reference to your question Samiam4, I plan on restoring the car and driving it for quite a while.

I will let you know how the replacement went.

I'd suggest calling everyone you can find on NEW axle prices...

since you are going to keep the car. The price variation is significant. New ones will be the later style. The only exception would be a Lobro/GKN rebuilds which seem to last very well.

I'll spare you all the technical junk on why rebuilds are done remanufacture in a way that limits their life.

The other option would be to find some good used axles-maybe out of a 240d. Lot of work.

May take the "lifetime warrentee" route which ussually is dissatisfying after 3-4 years and a couple free replacements.


Sincerely,


Michael
