I had both front wheel bearings/hubs replaced 2 years ago. Less than 20,000 miles in 2 years on them. Getting the same sound again. I'm being told by mechanic that both need to be replace again. Is it possible for them to go bad this soon? What could cause them to go bad so fast?

 

Where did you get the parts (new OEM, new aftermarket, junk yard, etc)? It is definitely not normal for such premature failure.

 

The mechanic got the parts. Didn't look at them while he did the job. I had a "1 year warranty" with the job, but that's expired. I don't want to get this done, only for it to happen again in 2 years.

 

Time to find another mechanic...

 

what are some symptoms of bad wheel bearings? My steering is sloppy on the highway and car is very unstable. I got Kybs with eibachs installed , new tie-rod ends and lower ball joints as well about 7 months ago. Could it be wheel bearings? or maybe inner tierod ends?

 

Could be possible that they go bad in 2 years. It would depend on the parts used and the knowledge of the person installing them. If they are installed incorrect then you bet they will go out soon. I put 220,000 miles on my original bearings and hubs. I expect to get the same out of the new parts I just put on.

Though on a side note I am suspicious of how a lowered suspension wears on the bearings. I noticed that when both of mine went out the bearing chewed up the inner section of the hub (part farthest from the wheel studs). Only time will tell if its because I was lowered or if this is just how things normally happen.

 

I am curious how a lowered setup wear out parts.

I've heard over torquing the axle nut can cause the bearing to go bad. Have you hit a lot of pot holes? or bumps?

Its intersting because my brothers Max, had new bearing put in about 8 months ago, and its starting to make the same noise again. . .

 

Did they replace the hub at the same time?

I generally do not run into pot holes and such. Texas roads are pretty well maintained.

 

Texas roads are pretty well maintained... except in Houston (inner loop at least)... My suspension is shot after 6 months of living in the medical center here. Roads are horrible.

 

Over torquing the axle nut will definitely wear out the bearing prematurely....been there...done that....wont make that mistake again. Make sure you know the mechanic is not doing that.
