Hi, I have unfortunately with my blazer the problem that the front axle (think I at least) cracks during the ride with open freewheel hubs. The whole looks about like this: If I drive with open freewheel hubs (ca from 80 KM/h) and go down from the gas there is a short cracking or to the coach transmitted throbbing (but I do not speak of the normal driving noises of an amis ) . The same is then also when I go on again on ́s gas. This short cracking or. When the freewheel hubs are closed, this problem doesn’t occur… I changed oil a few days ago, but I saw that the joint of the front cardan shaft (on the right side) is already pulled out. I don’t think it could be because of it but I wanted to mention it (you never know ) Can someone help me? MFG Patrick
