Nate Fwiw I didn’t separate my driveshaft at all. After removing rear flex disc, was able to slide it out in one piece. No huge wrenches, no loosening nuts, making marks… Much easier.

As Usual......
 

So much help ! :) .

THANK YOU ALL ! :sunny: .

It occurs to me that if I support the rear suspension I can then rotate the wheels and snug the 46MM nut up, correct ? .

I only know the method I previously described.

I looked up the drive shaft stuff because I was curious. I wonder how long Dorman has been making new drive shafts for W123s?

If someone is changing the drive shaft support and or the drive shaft support bearing you have to separate the drive shaft section.

Thanx
 

Okay ;

I've been searching and carpart doesn't carry the 1982 240D one .

It appears the one for an automatic (722.117) tranny is different .

None of the ones I've found seem to have the boot even though the parts catalog says it uses one .

Hm........

Maybe I'll jack it up and take it apart, see what's what .

Sumit racing is showing 2 driveshafts for the 82 240D. Perhaps you can use the part numbers. Be a sure to re-check my accuracy.

Yet MORE Help
 

Thank you , I did just that .

The one with the twin 'Y' ends is for automatics .

No one seems to have them in stock, I'll post back what I do here .

Progress !
 

Okay ;

The weather and reduced pain levels finally allowed me to jack it up and take the driveshaft out, only the rubber center support is bad (bearing is smooth as is the U-Joint) but I can't see not doing the job 100% after close to 500,000 miles .

The center boot is different from the ones shown in parts catalogs, I guess I'll order one in along with two new Guibos ~ the boobs who did the (crappy) transmission repair must have used an impact wrench on the Guibo bolts, I had to use box end wrenches carefully places and serious OOMPH to get them all loose . they're originals and have a few tiny cracks but now's the time so out they go .

I was looking up in the floor tunnel and realize I've never really done a serious cleaning up in there, I saw a 1/8" coating of oil and road munge, as long as I had the car up on jack stands over Concrete why not do a good job of it .

I also noticed one of the Homeokinetic drive axles I replaced in 2000 or so when first I bought this car has a small perfectly round hole in it that allowed grease to cling out all over the passenger side read suspension, the pumpkin too had a thick layed or really hard crud on it and even the muffler and resonator had a thin coating of oily buildup so time to address all that, whew what a nasty, filthy job, I used multiple brushes and a thick microfiber rag to really clean off a massive ab=mount of crud, by the time I was done my driveway was much cleaner too, I hope I'm done there but we'll see .

I *think* I've found a place to rebuild the driveshaft, we'll see next week ~ for now it's all clean and shiny, wasn't hard at all to remove once I got all the bolts loosened and removed .

Any So. Cal. drive shaft shop suggestions ? .

722.117 Tranny Question
 

I neglected to mention I dented the automatic tranny pan, can I use one from a 5 cylinder car ? .

Peach Parts doesn't list it at all .

TIA,

If just a dent than just bang it back out, ck. for leaks.

Nate, I think you can use a 5 cylinder pan. If the pan gasket interchanges by part # the pan also will

722.117 Tranny Oil Pan
 

It turns out it fits the OM617's up to 1980 and some of the 450SL's too .

I was going to go yard hopping today but my idiot brother's '81 300SD finally ate the alternator belt that's been howling since January so I had to go rescue him today .

Maybe Monday .

I know I could bang it out but this is the four bolt pan so I'm concerned it might weep or seep and God knows every time I looked under the car during oil changes etc. it would drive me batty (er) .
