Uplander wheel bearing adventures

[asand1]

I ordered a pair of Callihan wheel bearings from ebay for $69, because both front wheels were shaking like Michael J fox. One arrived with a dent on the ABS sensor shell, deforming the seal and rendering it useless. The seller has another on the way with no mention of returning the damaged one.
I decided to repair the worse of the two sides today and found the axle nut loose, like two fingers on the 1/2" ratchet loose. One of the 13mm heads on the bearing bolts decided to start rounding AFTER it was already broken loose.
Everything went back together fine with blue Loctite paste, including the axle nut(wish I had red for that though). The axle has no means for mechanically locking the nut, no cotter hole or key way for swagging the nut or anything.
I knocked the studs out of the old hub thinking it couldn’t hurt to have spares.

Found these torque specs online

Fastener Tightening Specifications

118 lb/ft seems very low, but I researched it and found the same answer everywhere I looked.

good to know, thx.

Q.

The axle nut is one time use only, buy a new one and hand torque to spec, no impact. I used an impact once and the nut backed off and the axle was ruined. Check with auto store/NAPA or worst case Dealer.

Blue loctite won't be strong enough but I guess it's better than nothing

 

[asand1]

Today I will pick up the new nuts and red Loctite.

Packaging for the damaged part.

Dented ABS cover/seal.

Threaded flange

 

[asand1]

I took photos and emailed eBay seller brake_overstock, and he sent me TWO more wheel bearings.

Better packaging.

Stock style thread insert.

I finished the install today with new axle nuts and Red Loctite, and all torqued to spec..

 

[asand1]

All in all, have to say I am pleased with the purchase and the seller. Time will tell how they hold up. 80383 miles at the time of installation.

What is it with wheel bearings nowdays. Seems like we have gone backward. I had a rear go on my old Forester. Before that, never, ever replaced a wheel bearing.

I question GM with the 118lb/ft torque and no cotter/swage.
