Hello Folks,

I have a bad hub assembly that I'm going to repair. Some of the videos I've seen say the bolts are "tighten to yield" meaning you use them once. Where can I get new bolts from or even find out their part number before taking everything apart.

Also, is it absolutely vital that I use new bolts?

Any help is greatly appreciated.

I never have. Haven't ever had one break, knock on wood.

I've replaced all 4 hubs on 3 separate GM vehicles of various age and mileage and have never had an issue reusing the old bolts. Torque them to spec (as close as you can) and send it.

You can go with the old bolts if they look alright. I used new when I did mine but I'm paranoid about simple things failing and costing me a lot more. You can see my slide pin story for that.

My opinion:

Buy and install new OEM bolts. I’d bet most GM dealers have them in stock. The bolts are a critical suspension component and I would not trust reusing bolts, especially those that are stretch-to-yield.

Peace-of-mind is cheap. If you use new OEM bolts, you wont be driving on expressway at 75 mph with your family in the car, wondering if the bolts will break.

Honestly, new bolts are way too cheap to go out of your way not to buy.

Sorry. just realized nobody answered your original question. Most parts stores will also have the bolts but rockauto has pretty much always worked for me

If the bolts aren't corroded and aren't torque to yield I re-install them with loctite thread locker.
Torque to yield bolts will list a torque and a final torque angle. Example 55ft-lbs then 90°.
Many electronic torque wrenches include an angle function now.

I get mine from RockAuto. I install new mounting bolts and spindle nuts when replacing the wheel hubs.

^+1 on Rockauto, Ebay Motors, Amazon, dealer, or parts store being sources for the 3 hub bolts and/or axle nut. On the other hand, like hatzie, I've never replaced hub bolts or axle nuts. If not damaged, wire brush the threads and add a dab of medium blue loc-tite and reuse. Iirc, they're not tty (torque-to-yield). Again, iirc, Rockauto carries a couple of brands of hub/bearing assemblies that come with the 3 hub bolts and even a couple that come with the 3 bolts and an axle nut, though most times the bolts/nuts are sold seperately, but a cv axle will usually come with a new axle nut.

Notice there's no angle mentioned.

If you figure liquid Loctite is a messy spillable pain in the neck you're not alone.
They make A lipstick applicator tube full of Loctite paste that doesn't spill all over your toolbox or shop cabinet drawers.
I have the Red and Blue paste. The blue paste is Loctite 248.
Loctite 640 high temp sleeve locker I use on bushings and the Loctite 518 I use on transfer case halves instead of RTV is only available in liquid. I have a 3/8" plywood box with 1/8" underlayment plywood separators in dado slots to keep this stuff upright in my toolbox drawer.
The paste applicators ain't everyone's bag. If you like the liquid use blue Loctite 243.

I replaced one without new bolts, before knowing it was recommended, and everything was fine. The second two times I have replaced them I bought the bolts. They aren't really much.

Thank you!! I was able to find the bolts at Advanced Auto and buy them for about $12. Not as cheap as RockAuto, but better than nothing.
