Mark the bearing or bushing BEFORE you insert it to make sure it starts in straight.
If you are pressing in a big bushing or bearing, this marker can save you a lot of grief. If you don't get it started straight away when you begin pressing it, it can bind up and may be hard to get back out. In some cases, you can damage the parts. Watch the video below as Kent shows you how he used this style of market when installing a new bearing and the hub in a GL450.
