Differential

Much more common to have a tight universal joint. Often if you look closely at the bearing cups, you will see evidence of a reddish-colored rust around one of them.

We do not do that on this site. I am in the middle of Wisconsin. We have a huge number of very reputable dealerships and independent shops, and one well-known crook. We also had a real dishonest independent shop, but he went out of business a couple of months ago for lack of customers. He was on a real busy street in the center of an extended community of over 100,000 people. I do not know the names of any shops in any other cities, and I would not have any idea of their reputations.
