I know the annular one I had that seperated used grease. If anything grease is less likely to leak?

I'm not all that excited with the grease approach as well. The centrifugal force will tend to sling the grease off the balls and onto the inner walls of the boot. It's impossible to fully pack the boot with grease to the point where there is no air surrounding the balls.

The original design used oil...........probably for a good reason.

The boot is tapered meaning at speed the c force will make the grease go towards the axle end. Packing it full wouldnt be necessary. The same problem would apply to oil as well.

The grease will stop in each of the sections........not all that much migration toward the small end. But, it will certainly pack itself on the inside wall of the boot.

If you fill it with oil..........there is no issue.

Wouldnt the grease get more fluid as it got hotter? Not arguing, just interested.

Probably get a bit thinner.........but, I don't believe those axles generate any significant heat.

1985 300D Rear Axle Replacement

I noticed the differential on the 1985 is bolted to the subframe on the front side in addition to the differential mount on the back side. I don't believe the 1984 was bolted on the front side because it moved up and down once the differential mount was removed. It was a bit tricky to unbolt the top 2 differential cover bolts on the 85 because I could not lower the diff.

Yes, I'm in the process of replacing the axles on my 85D.

The 85 should be like the 84. maybe your 85 has the ABS wire and connector on the Differential. on the right side towards the top. maybe the wire harness is not letting it drop enough.

I think there is a bolt holding it in the diff.

There is 4 studs on the Diff that fit into holes on the front and rear side of the Sub frame, and bolted to it. then the Differential mount with the 4 13mm bolts that bolt it to the body.

Could be that the rubber brake lines are keeping it from dropping enough. remove the calipers and hang them on the sway bar with a bungee.

No ABS on the 85 Charlie. And no harnesses, hoses or cables in the way. I didnt look that close but the diff appeared to be fastened to the subframe on the front side kinda behind the flex disc. I'll look again tomorrow. I'm kinda pausing with my work right now till probably next week. I might have to get me a new diff mount anyway just to renew the old one.

Update:
Just looked. My diff is definitely bolted to the subrfame on 4 points - 2 at front behind flex disc and 2 towards rear above each axle connection.

yup. the diff is bolted to the subframe. and when you take out the diff mount bolts, the diff and the subframe will lower about 4 or 5 inches, and you will have room to remove the axle.

VST, it would seem that the best position for the axle removal is at its present state which is the highest level of the differential as the axle is most extended. What do you think. below are pics of where it is bolted.

nope.
it won't come out.
don't ask me why, I fail to understand... I've just removed DOZENS of axles, and I have to lower the diff on them to get them out, or in.
it must have to do with binding, or something. I KNOW you have to have it dropped to reinstall them.
most likely, you will need to lower, remove, raise, push and pull to get the axles in and out.

It would seem though that even with the diff fixed at that position that the shocks can be raised and lowered (by jacking it up or down) to "wiggle" the axle if necessary - essentially achieving the same thing as lowering the differential. Thoughts?

FYI

I just talked with him on the phone.

The 1984 300D is missing (lost by PO?) the rear studs from differential to sub-frame.

The car is off the road in storage, so the issue will be fixed at leisure.
