That only helps once the axle is out if Its seized. I tried pretty hard with the axle in to pull the hub out. Never gonna happen.
My calculations predict impacts of 12-15,000# with 3-4# hammer which is far more than needed to move a hub out of a bearing
You never want to use impact to press a bearing. Impact kills bearings in fact BMW has a TSB to preemptive replace a wheel bearing on any wheel that was impacted in a crash. (that by the way is how most wheel bearing failure happens. Pothole in a curve). If the seal doesn't fail, a wheel bearing can last a million miles .
I've never seen a bearing you could drive on that looked this bad. This was the bearing I replaced related to the axle that was fused. |
Those aren't a puller type tool. You hammer on it with a sledge.
I watched a few videos of people removing the hub WITH the axle still attached, mind you it wasn't on an X5 but still seemed to do the trick with some really rusty bearings/hubs/axles.
