07 Sierra SLT - replacing front bearings

[mikea57]

I'm getting ready to do a brake job on my truck and I've been noticing a roaring sound as I drive. The sound is usually louder when I'm going more slowly but I'm thinking engine and road noise could be masking it as I go faster. I figured that while I was under there I'd check the bearings. I went out to YT to see if there were any videos on the subject and there was one, but in it, he simply replaced the whole hub bearing assembly. Is this how bearings are serviced now? You don't fool with individual bearings and packing them with grease nowadays? I guess I'm behind the times if so!

The bearings are a hub unit. The whole assembly is replaced

[mikea57]

Sounds expensive. What's the cost for these new fangled hub units?

[txab]

Aftermarket, around $100 up

Try 200 and up for a GMT 900. Really easy to change though. I've done quite a few of them on many different vehicles. Just remember you will need to use a torque wrench to set the axle nut preload.

Thanks! Guess I'll check both and hope that it's only one that is being a whiny baby...

I had to do one of mine in my 07 vmax at 130,000 km.. The other one is still good.. it has 207,000 now
