Easiest way to remove a differential
 

Is it possible to remove the differential without dropping the rear subframe? If so, what is the procedure?

I am sure that I removed the differential with axles attached in the W123.

Remove end nuts holding on axles.

Remove rear flex plate on driveshaft.
Removed two 19mm fasteners at top of differential.

Couple more fasteners and dropped right out.
Left subframe alone.

That is how I have done mine. It was really easy. Just leave the axles attached. You still have to move the subframe up and down to get the axles in. But it is really easy if the car is already supported properly. Also, in addition to the above you will need to loosen the center carrier bearing mount so you can slide the drive shaft forward enough to pull it off the diff.

It still took me half a day. But, that was because I was doing a ton of other stuff back there. The diff. was not that hard. The toughest part was accessing those nuts on top of the diff. If the car is a "scrapper" you can cut a hole in the floor to make it easier to remove the nuts on top of the diff.

When all fails, you do this. now you don`t have to contend with those pesky 19mm bolts :D

Installation is reverse of removal. :jester:

Hmm. where do I hook the chain...

Wrap it around the sub frame.

my time to chime in
 

Okay --- first things first; while I really like the gentleman from California (see post above); however, I learned the chain is wrapped around the front support bar of the driver's seat for easy removal! See pics in the link below.

And the same post, definitely illustrates the easiest way to remove a differential. Give you a hint --- a forklift helps!

Data needed.
What car/chassis is this?

Who, me???


ROFL.... :D

Yes it is but make the job hard on you and the drive shaft flex disks.
Its just four easy to access bolts to lower the diff and sub frame 5 - 6"
then the rest is easy.

My question applies to a diff in a junkyard car.

On a serious note see link. http://www.peachparts.com/Wikka/W123Differential

Deliveryvalve`s write up is excellant. Just follow it, and you won`t go wrong.

However, in a JY, you won`t have the luxury of a Jack. you won`t be able to raise the Differential to get high enough to remove the axles from the hub, unless you find one the workers forgot to remove.

It is possible I suppose if I read one of the above posts correctly, that mentioned to drop the Diff with the axles. seems they would hang up in the hub splines and not slide out. that is with the Homokenetic axles.
It`s hard enought to remove one w/o additional hang ups.

If the Annular axles were installed (two piece) then it would be easy to remove.

Especially in a junk or pick and pull yard. Just undo the four bolts at the rear of the diff and let the subframe and diff hang on the emergency brake cables. Then you have easy access to the bolts on the top of the diff. Wire a 2 x 4 across the diff and axles so the axles won't fall and damage the CV joints.
Don't bother to undo the drive shaft center bearing slip ring nut because the diff assy can be just pulled back from the flex disk. Also the flex disk is much easier to unbolt when the sub-frame is dropped.

I want one. :D

I have done this twice now on 84D & 85SD in the JY. I take my own blocks and jack to support the diff to lower it. Remember to unbolt the axles in the hub and give them a tap with a brass bar to get them moving then start lowering. Shift the diff to the right and pull out the left axle from the hub, it will rest on the exhaust pipe. Next move the diff to the left and slide out the right axle from the hub.
Don't even drain the oil.

Charlie,

You would be correct! That is the write up I used from the DIY section to replace mine.

I followed that thread/post to the letter and had no issues at all. Including getting the little stub 1/2" drive wrench.

I just installed the one I had with the axles intact, since I had a complete assembly with axles still attached.

Thanks again DeliveryValve!!
