Front bearing going bad - repl both?
Between the noise and the slight play in the 12 and 6 shake it appears my d/s front bearing is going. Passenger side seems fine for now. Should I go ahead and repl both? Do they generally go bad at the same time?

For the time it takes and the whole "Since I already have the car in the air", I would change both just for peace of mind.
I had one go bad and I bought both and I think we did both in my buddy's garage without a lift in 90 minutes from taking wheels off to putting them back on. The upper bolts are a piece of cake, but the lower bolt is blocked by the ball joint, so you need to detach it. That takes the most time.
Hope that helps some.

IMHO- I would replace both bearings while you are doing the job. Since you are tracking the car spend the extra $ and get the SKF race bearings. Piece of mind that you are running the best available equipment is priceless.

Not to say the sky is falling but don't assume both fronts will wear out together. After several years of autox and track days on Kumho 710s I first lost a left rear (which I replaced at the track with a Delco) and then a week later a left front went out. Actually, they both sheared off. Apparently, I was taking more right turns than left. I decided then to replace all four with SKFs and keep the new Delco as a spare.

I replace ALL my bearings when one goes bad. They will eventually all fail close to each other...and while I have it in the air, I may as well do them.
It hits the pocket...but at least I know they are ALL good...

I agree. Once one fails I don't think the others are far behind from my experience. The fronts tend to go first in my experience.

I had the second go bad after 2-3 months, the third a month or so later...etc.
Just get it over with...I keep the ones NOT so bad and have them in case of emergency for track changes. MUCH better to replace them all at the same time.

I don't replace both especially the front which is simple to change. I have not had both fronts go bad at the same time. If you have enough money to waste a part with service life left in it then change both. Give the part to someone else to run. I have put on several used bearings and gotten the rest of the moneys worth out of them!

I have simply replaced my failing OEM ones one at a time, as they fail, with SKF race units. There are no issues with this. My OEM ones lasted anywhere from 1 yr to almost 3 year.
There is no common labor to doing 1 corner at a time, so it's not any more work to mess with another corner down the road.

On the c5z I will prob do each corner at a time. Like drivinhard says, NO common labor.

I replaced all 4 with the SKF bearings when I installed my brakes since it was already apart.
You can not use OE rears on front becasue the bearing on the rear is secured buy the axle nut. The SKF performance bearings have them rolled, so you can use them on the front or back.

Don't see anything gained by doing the other until it is ready. May try to get a volume discount on two then at least have it ready.

I might take this approach if I was doing track days or autocross, but I am not going to drive 750 miles one way to a track like Miller or even 200 mile to WSIR and have a hub fail in a 35 minute national race. When one fails I am going to replace them all. As it is now, I preemptively replace them all about every 18 months anyway.
