Sure, it's easy now to say repack your bearings every time you do your brakes.
i pull into the company parking lot and hear crunching from the car. Looking underneath I see oil dripping from the front differential. Adding 2 + 2 and getting 5 I consult the elite experts who soon disabuse me of the notion the front differential is engaged in anything other than 4WD. I knew that.
Next likely suspect is the wheel bearings. Raising the driver's side wheel it wobbles, methinks I've discovered the culprit.
Following Haynes served me well, first off is the hub.
After removing the C clip, not a snap ring as Haynes says and the rest of the stuff as shown in pic the rotor comes off, The pieces of detritus shown is what's left of the roller bearings.
The inner race is firmly attached to the spindle and requires a little Dremel action to remove.
Oddly enough it rotated fine it just would not come off! You can see in this pic it had worn a groove in the spindle, easily fixed with 220 grit.
The rotor also had the cups still in them and were impossible to remove so I reused them. I'm changing the rotor tomorrow and I'll put the new cups in.
Everything buttoned up in reverse order. I neglected to put the spindle on with the key way up, I'll also fix that tomorrow. I couldn't get the cam back on but I got enough together to drive the vehicle home.
Here's the question, note in first pic all the grease in the hub, does it have to be replaced? A light coating on the cam and spindle spline, sure. But should the hub be packed? I've noticed this in some of the other pics also so I'm kind of leaning towards packing it with my pretty purple wheel bearing grease.
Any thoughts?
Also is there any trick to getting the cam on? I had the key lined up but I was upside down as explained above. Tomorrow I'll have another go at it.
