I worked on this all day yesterday. the diff is different than the one I pulled. Has anyone done this? It was all smooth until I tried to bolt up the 4 bolts in the back. they missed by an inch, luckily as was trying to figure out how to fabricate an extension I put the mount on backwards and it lined right up.

so I have it all together and I am getting a rubbing sound. I did many things at the same time so I cant account for it with any one change and it was too dark to finish last night. my list of changes are:

1. replaced differential with 500SEL donor
2. replaced axles with new Cardone rebuilds
3. replaced rotors, calipers and shoes
4. installed lowering springs

My question is: since the 126 housing seemed to be a little wider, does anyone know if maybe the combination of the 126 housing and the lowering springs would make the axles too long to fit?


The sound is coming from both sides the best I can tell, but it has a harmonic tone which sounds like the disk. I am hopeful it is just the disk rubbing the caliper. My old calipers and disk were junk so I can put them back on. I will raise it tonight and see if I can find the noise, but if anyone has put in a 126 diff and can give me some confort level that the axles fit ok it would make my day go easier until I have time to check it tonight


the disk on the driver side was cut in two, it seems like maybe it was not releasing completely. Is there something at the system level that would hold pressure on the rear brakes, like a bad proportion valave or something? I did not replace the lines but Im thinking the one in the back looked kind of bad, would that make any difference to the sticking issue?
