65K miles, look at my bearings!!!

**tatertot91** · 02-12-2010, 07:14 PM

Still can't believe how bad my bearings were
This came out of the rear end of my 65K mile Z
Had to take care of the leaking, whining, crappy geared rear end
All chewed up

**sjsingle1** · 02-12-2010, 09:05 PM

WTF??? is that why my rear end sounds like a drunken monkey in a 55 gal drum???

**zeetwentyeight** · 02-12-2010, 11:14 PM

Yea really my sounds like crap too, how hard are they to swap out and price i wanna do mine asap, mine is about to hit 120k miles

Yikes Tater...

All too common,but suspicious sounds from a rearend do not necessarily mean bearings.Axle bearings,carrier and pinion bearings,and gearset(whose lash has changed from wear)can all cause suspicious sounds.Our rearends are notorious for leaking pinion seal and we see the drippings when the car sits,but we don't see what has leaked while driving.We need to habitually check fluid level to help minimize those bearing failures and other failures.My OEM passenger side carrier bearing went the same way as the pics.

Ouch -- them are toast. Strange how it is basically one sided on the race.

Yeah i found that to be a little strange also
At least they're all done now
and i got my 3.73s

Were the pitted side of the races on the top?

**Wesman** · 02-14-2010, 11:35 AM

Looks to me line something definitely got into that bearing. Was the axle seal bad??

Honestly don't remember, would expect the pitted side to have been on the bottom

Don't think my axle seal was bad

**joejenkinsglass** · 02-14-2010, 04:52 PM

looks like at on point in time the rear was in some water.

**JaycenK** · 02-15-2010, 05:41 PM

looks like that rear broke at one time and who ever didn't bother to check if the peices got into those bearings.

**ss~zoso~ss** · 02-15-2010, 06:03 PM

shit that aint bad, throw em back in with a quart of MMO and you'll be good for another 65K!

**c5z28** · 02-15-2010, 06:05 PM

damn makes me want to go put another magnet in my rear end. What happened to the 3.55's?

Was told from this guy that they were Richmonds for a 7.5" rear, richmond doesn't make 3.55 for a 7.5"
They were for an 8.8 so that idea was scrapped, ended up with GM 3.73s and i'm happy, now i need some better tires, fuzion 275s give me no traction whatsoever

**c5z28** · 02-15-2010, 06:14 PM

Well damn did you get a look at your bearings on the axle? I was told the outer bearings don't have races they just ride on the axle.

Not sure, don't know that could cause this to happen

Could see this being a possibility

I'll do that and swap rears with you

i never got to inspect those
They don't have races from what i remember, they got replaced anyways

**c5z28** · 02-15-2010, 06:24 PM

So what is your rpm at 65mph?

**tatertot91** · 02-15-2010, 06:35 PM

Would estimate about 2250-2500
According to my OBD2 my rpm gauge is about 250rpms off
i just ran up to daytona for the wekend and averaged about 20mpg at about 70mph, there is more in it though
