sorry.. that changes a whole heck of a lot..
yeah.. bet THAT swap would give some sweet hwy cruise..

Ok cool...So the swap will work with lower rpms in 4th at 60mph correct?

Ok lets make real sure...
CURRENT CAR
81 240D 617.952 4SPD 3:69 CONVERSION
DONOR REAR END
83 300SD 617.952 AUTO 3:08 STOCK
I will be placing the 3:08 into the 240D 3.0<-correct?

positively.. that would be outstanding on the open road.
forced is the sage though.. calling shims out of the air.

Well cool to work I go....I wil post results shortly...Has anyone tried this combo before? Like you forced?

When I still had mt TD, I swapped the 3.08 for a 3.46 from a non-turbo 300D. It can be done with normal tools. It just takes time and alot of strength.

Be sure to have a long breaker bar available, get the car as high in the air as you can get it, take the axles completely out, swap the shims, and you might have to use the 240D's rear case/mount.

Well I'm hoping the rearend will make my car more interstate friendly...any ideas on the loss of lowend? The 3:69 is fun but man on the cruise it hurts..engine seems to be screaming..will see shortly though....any suggestions will be thankful....

Seems lining up the rearend is becoming a pain, round 2...

Ok now thats much better...The 3:07 feels nice and the engine dosen't sound like it's screaming...Oh and there is still plenty of low end power...Thanks for the advice

great to hear it.. and might add timely. nice work.

I bet it's faster to 60 now too. The 3.69 does not allow boost to build in 1st and requires too much shifting. How is it off the line? Do you have your ALDA adjusted? I plan to do the same swap eventually.

A few months ago, I bought a bunch of parts from some dude, and included was the rear diff and (2) good-seeming shafts off an unknown doner.
The donor diff has "R 1153513208" stamped on it (the same as the OP of this thread)...but I've looked everywhere and don't see a ratio.

I've got an '85 300TD wagon with what I imagine to be both a worn differential and a bad axle shaft on one side.

(The whine sounds like a ghost creeping up on me when the drive shaft is loaded...typically around 20-35 mph. Changing the oil didn't help. When you put her in Park, she'll "rock back" quite a good bit.)

Anywho, I figured I'd replace both the differential and the axle shaft(s) at the same time.

Anybody know the ratio of the donor rear end and that of my wagon? Any way to test a rear diff for wear/noise when it's not in a vehicle? Thoughts about whether I can/should do the swap?

FORCED, you say the axle shims are different from the "D" and "SD" Differential, and to swap them.

I think from what I have read from other axle threads etc, the shims are specifically for each Differential, and not to swap sides. Let alone to swap them from diff. to diff.

Or am I not filtering the input through the bone structure and something is lost in the translation?

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

Check here the lower left corner.



But to be certain of the gear ratio, remove the cover and count the teeth on the ring gear, and divide by the teeth on the pinion gear to get the ratio.


On your Euro, if you have a non-turbo motor. Then most likely you have a 3.46 ratio diff.


The only thing I can think of is to open it up and look at the ring gear wear and check the backlash.

Sorry Charlie,

I am thinking Lance will not be answering your question anytime soon here.
