How To: Front hub replacement
#11
If you have all the tools this takes about 45 minutes to do on each side. I originally thought it was road noise from the tires but did some reading and found out the wheel bearings are known to go early. I also found out Chevy has a 100k warranty on them so if you start hearing humming noise resembling road noise have them replaced.

No bearings to pack, sealed units. Pretty easy to swap out also.
EDIT: It's a 30mm axle nut.

ok, here it is again... with pics!
starting place- took off the calipers (14mm) and rotors to get to the real problem...dont forget to unplug the ABS sensor

here is the trouble I first ran into... the axle nut (30mm) is on there good... 155ft/lbs How do I get it off with the wheel and brakes already off? I looked all over the shop and found some angle iron I had laying around and bolted it on to the lugs (it didnt matter because the new hubs had new lugs... https://www.chevyhhr.net/gallery/fil.../hubremove.JPG
then its 3 15mm bolts to get the whole thing off...

Keep an eye on how the brake shield is oriented ( took me a second try after it was wrong).
Reinstall- I used blue lock-tite in everything... 85lbs on calipers and hub bolts, 155 on axle nut Viola!

You forgot the part of the procedure that says to "place a punch or similar tool in the brake disk vents (before you remove the caliper bracket) and brace it against the caliper bracket". Then remove the axle bolt, reverse the same way.
And, yes real easy and you should consider replacing the axle at the same time. Only $60 a side and no real extra labor. And maybe the control arms ......?

I didn't have to do that. I left it in gear and just hit it with the impact. Took it right off.

I can't understand why there is so much 'write up' on this. These have got to be the easiest hubs I've ever changed on a vehicle......
