Supports, far from new, the owner himself immediately proposed to replace. They did so, but the clicks did not disappear when they started. Put a new SHRUS, tested … - still clicks!
The hub bearing remained under suspicion. Everything seems to be in order to the touch - no hint of backlash! But, as you know, miracles do not happen in a car, so they removed the hub. And they saw what is shown in photo 1. It turned out that the inner ring of the bearing did not rest on the hub shaft not with the entire landing surface, but only with a narrow strip of six to seven millimeters. Why, now it’s hardly worth figuring out - marriage, it is marriage! But because of it, with large loads on the bearing, the inner ring (which, we recall, is pulled together with the nut effort adjacent to the packet!) Elastically shifted, sharply choosing the gap, - there was a click. Obviously, when checking backlash by hand effort, this effect cannot be achieved, but on the go - easily! This is evidenced by a wide dark stripe at the end of the shaft, as if the birds had pecked. These are pitting marks, the result of impacts of the bearing ring on the shaft (photo 2).
Further trivial: replaced the hub and bearing - clicks disappeared.
