I hope it gives a rough idea. It is a simple plunger assembly - one pipe in - one pipe out.

That is great. Thank you. I was also thinking a flexible type funnel that I used to own might work as well.

Bad differential or axle issue on drivers side. There are 2 metal wheels. One on each side of the differential box. 1 seems fine. 1 seems a tiny bit off or warped.

Those metal discs are mass dampers, added about that time to quiet down the gear whine in the differential. My '89 190E 2.6's ring & pinion sang like a birdie when the car was new and after two diff replacements the MBUSA rep said "We have a redesign coming soon if you can wait and we will install one in your car when it's available." Almost two years later a new diff assembly arrived with the mass dampers and the noise was gone. This noise was in the six cylinder 190E, not the four cylinder. I had one of those dogs also, much to my regret.

I was curious to know the name of the wheels. Can the dampeners cause any problems?
