Wheel Bearing(s): Which one(s) did you replace and at what mileage

[jakecro]

Hello all,

I'm looking for a little help in some data collection regarding wheel bearing replacement.

It seems that at one time or another the wheel bearing(s) will need replaced on any S4. I am looking for some input regarding which wheel (RF, LR, etc.) bearing you have replaced and the mileage of the said bearing.

Also, once I have the time I would like to put all of this information together on a spreadsheet to post on my site.

Thanks for the help!

I just found out both my rear wheel bearings are starting to go. My S4 is at 110K.

[audinoobs4]

Right rear is out at 69K. in shop as i type(warranty)........According to the poll thats the one that goes out the most...........Interesting................

[peterc23]

front left went first
then both rear had to be replaced last month
and front right is starting to make noise
car is around 70 000kms

[WingsnHorns]

Just had my right rear replaced and now the left rear is making some noise and this is at 112k KMS.

[jaybquick@JHM]

120k and none changed.

I think people in snowy climates tend to see higher failure rates due to the salt on the roads accelerating rust and eating at the built in seals and causing them to fail.

One Drivers side rear at 135k miles.

[OldYella]

Just replaced Pass. Rear just before 80k

[ChriS4]

none yet, 61k
*knock on wood*

[GyzmoS4]

Just replaced pass. rear. 104k

[AudiSportB5S4]

front left went first
then both rear had to be replaced last month
and front right is starting to make noise
car is around 70 000kms

what noise do they make when they are on their way out ?

ehummm its kinda hard to explain lol
on mineee there is a particullar loud sound (resonance) at like 50kmph
i live in canada and been driving in the snow this winterr which was a bad idea
its just sort of a howling soundd kindarepairing soon gd luk

[b5s4blk]

replaced right rear about 1k ago at 88K. Replacing driver rear this weekend along with new TRE's

[Dowskeet]

137k on the body and wheel bearings and its still good to go.

Gotta love the south.

[Reich]

replaces my rear rr at 98000kms which is about 156000miles. I think my front rr is coming

[GyzmoS4]

Well mine sounded like i had another motor in the back of the car with just one long gear.

[drkenan]

Pass rear @ 80k and I believe previous owner did pass front @ 60k.

[points]

Both rears at 59k

[Bernie]

Left rear at 80,000 and right rear at 85,000

[audinoobs4]

Shop Called me back and not only is the rear pass shot the rear drivers side is going out too. no wonder it got so loud(69K miles btw). this is a good thing cuz now instead of paying 100 deductible for the one i only have to pay 100 deductible for both. ha sucks to be my warranty company.

[RogueStatus]

i had to do my drivers front and pass rear before 60k...the way i used to beat on the s4 didnt help (blew the turbos at 52k too) but all my stuff (wheel bearing,turbos,etc) were under 100k warranty

By the way, why do you whant to know exactly which bearing failed?

[S4 in_lowplaces]

What kind of damage can be see if somthing like this goes untreated? Are there any possibility this could cause a serious accident if left untreated? Just want to know Thanks

[jakecro]

Well, both of my rears were replaced by the last owner and I think my driver front is getting ready to leave the party so I thought it would be interesting to see what bearing location had a higher probability of failure. Is that too much to ask? j/k

I would like to thank everyone for their input and will gratefully accept more!

Thanks!

Worst case scenario -- the bearing will fall to pieces in the hub, in which case the hub would want to separate from the spindle making the wheel fall off of the car - and if you catch it just before this happens you may end up having to buy a new hub and/or spindle if they get warped from all of the heat.

Best thing to do if you find yourself in this situation is have the bad bearing replaced as soon as it starts moaning like a ghost since it's only going to cost you more the longer you ignore it.

[Overboostin]

pass side rear at 120mi

The hub is attached to the outer CV, and goes THROUGH the bearing. If the bearing fails, your wheel won't fall off.

Had my passenger rear replaced today (168,000kms)

[Sniper512]

Passenger rear at 120,000km
Drives Rear at 140,000km
Fronts are still good.

[AMC]

one of my fronts are bad i think? wouldnt know till i replace them within a yr lol

[Cactus00S4]

103k, both rears at same time :)

[StuntManMike]

replaced RR at 110k and now at 120k I think the RR is starting to go out again. this time it's different though. I have the constant ghost moan of hum and yet only when turning left the sound goes up an octave. last time that didn't happen.

[OldYella]

As I posted above, pass rear before80k, then the rest around 85k. I replaced the wrong one and figured while I was at it I would get them all done.

Tires maybe? Tread separating on the Drivers rear?

[StuntManMike]

had the same thought that it might be tires but I rotated the tires yesterday and the sound did not change.

Weird.

[dpdaudi]

130k miles. Replaced all four at the same time. All of them were shot. Some worse than others.

[G.O.A.T.]

120k and none changed.

I think people in snowy climates tend to see higher failure rates due to the salt on the roads accelerating rust and eating at the built in seals and causing them to fail.

Jay, do you guys have an option to buy all 4 wheel bearings for a set price?
I see that each one is priced at $49. (fr) and $125 (rear). Something like $300shippedd.

[imola]

Replaced pass. rear at 102k and then both rears at 130k. Don't know why I had to do the pass rear twice

[GeeJayzS4tyme!]

120k and none changed.

That is interesting. Is it just those of us in the "snowbelt" who use salt that seem to have replaced them???

I voted. My d-side rear crapped out around 110K, and the p-side rear not much longer after that.
