Hi I'm replacing front wheel bearings on my 5th gen. I installed one side first (using bearing driver). Then turned the wheel over, inserted the long spacers that sits between the two bearings inside the wheel hub and started driving the second bearing in. At some point it became impossible to move the spacer by hand when the second bearing was sitted in. Also both bearings are very stiff to move by hand. Am I doing something wrong ? Does the second need to go all in or do I have to make judgment as to how far it's suppose to go? I believe the spacer needs to be lose and moving about freely in the hub as this is how it was before I started the job Many thanks for any responses.
