Rear Axle Independance

Post by JBog » Sun Nov 26, 2023 5:15 pm

I noticed some squealing last night at the holiday parade. I assumed it was just the 0 degree temps making my 1919 Touring ache and moan a little bit. Today I jacked up the car and ran it. I shifted it to high (my ruckstell was in low) and noticed the ruckstell side was very slow to start moving. The otherside was turning very fast. I just wanted to make sure this is normal behavior or something I need to take care of this winter?

Once I gave the ruckstell side a helping spin it started to catch up.

Here's a quick video of the wheels moving. I was also wondering if they are wobbling too much?

I'll say it's working as designed. Its called a differential because it can handle different speeds of the two sides. Just the slightest difference in resistance to roll in the sides will make the side with the less resistance run free while the other may not turn at all or turn slower. When you say it's the Rückstell side that did not turn is becaise the Rückstell mechanism give some resistance to that side.

They're not wobbling too much. I've seen far worse!

I would suspect that the brake on the left side could be slightly dragging. Not enough to slow the car or cause it to spin but just enough to slow that wheel. Also see if the wheel and axle on that side can be lifted up and down slightly when it is not moving but the brake is off. Leave it on the stands when you make this test. The bearing on that side could be a bit worn. Also might just be that the pressure of the pinion gear against the ring gear will give it a bit more tension on that side. There is no screeching or scraping as it turns, so probably OK just as it is.
