I'll add my 2¢. I had a slide puller- not enough umph, not even close. I did make that work by banging on the insert from the backside with a bar after heating the hub.
Sonny's suggestion for penetrating oil I will try next time.
Bought a tool from Motion Pro that was a joke- don't.
The last time I just moved the spacer with a good sideways whack with a drift and then banged the bearing out the old school way. That works every time.
I use the old bearings to drive the new ones until they're flush with the hub. Stop, or you'll stick the old one in there! Then use a big socket to bang in the rest of the way, putting pressure on the outer race. I'm going to find a washer that is the right size for next time to help evenly spread the load.
Rear tire right side bearings are always tight, but feel OK after removal. The axle torque is too much, but afraid to back off too much. Spec is 110 and I go 95- probably still too tight though. What are you guys using?
In an old post someone said that they took off a mm or two from the spacer. Anyone else done that or have thoughts on that?
