GnatGoSplat Posted December 26, 2009 Report Share Posted December 26, 2009 I was switching back to factory (winter) wheels today, and oh what FUN a lug stud snaps clean off! So I pull the wheel off and noticed that ALL the lugs are corroded enough that they're thinner towards the inside. I spent all afternoon pounding, heating with a torch, spraying with WD40, and could NOT get the broken-off stud off. Since all the studs look bad, I suggested to replace the whole hub rather than messing with studs and my wife insisted that's what we do. So anyway, the eBay ones are $47.75 shipped, or I can buy one locally for about $87 with tax. I wouldn't mind waiting a week to save almost $40, but are the eBay ones any good, or likely to fail in a week? Anyone tried one? Here's the one I'm looking at: http://cgi.ebay.com/ebaymotors/REAR-HUB-BEARING-OLDSMOBILE-CUTLASS-SUPREME-92-96_W0QQcmdZViewItemQQhashZitem518f0fda13QQitemZ350292531731QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories I've attached a pic of the old hub, I can't say I've ever seen this kind of corrosion on lug studs before. Makes me wonder if it has anything to do with AE 077's? I bet I damaged the bearing with all the hammering I had to do to get the rotor and hub out, not to mention all the hammering trying unsuccessfully to get the broken stud out, so probably a good idea to replace it anyway, though I hate wasting money unnecessarily.

slick Posted December 26, 2009 Report Share Posted December 26, 2009 Rockauto looks to be around $60-ish + shipping for a Timken. If you are in no hurry, I'd get the Timken, and skip over the cheap ebay one. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted December 26, 2009 Report Share Posted December 26, 2009 DAMN! they're like half as wide as normal! Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted December 26, 2009 Author Report Share Posted December 26, 2009 Oh yeah, I forgot to mention it's a rear hub. From RockAuto, TIMKEN Part # 512004 FWD; 4-Wheel ABS; Rear $128.79. Ow!!! Yeah, they definitely didn't look safe. I need to start inspecting the lug studs anytime I swap the wheels. I never thought to give them a close look before. It never occurred to me they could corrode in that way. First time I've ever seen anything like it. Quote Link to comment Share on other sites More sharing options...

White93z34 Posted December 27, 2009 Report Share Posted December 27, 2009 I've never met a hub that I could not pound studs out of. Regardless... I'd rather put a used hub on then one of the ebay specials. Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted December 27, 2009 Report Share Posted December 27, 2009 Stay away from ebay hubs, cheap China junk. Is the car that rusty, or did you overtorque the studs at one time? Quote Link to comment Share on other sites More sharing options...
cutty Posted December 27, 2009 Report Share Posted December 27, 2009 Is the car that rusty, or did you overtorque the studs at one time? That exactly what i was thinking over torque will stretch a stud. But i agree with everyone else about the ebay hubs. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted December 27, 2009 Author Report Share Posted December 27, 2009 Damn, eBay hubs being crap is bad news. Yeah, they do look like they may have been over-torqued. It's plausible that could happen if my torque wrench is out of calibration. I always torque using a torque wrench, and it's big enough I can't really feel how tight it's getting so I rely on the click. However, I compared the length of the studs with that of my spare front hub, and they're exactly the same length. It seems they really did just corrode that badly for some odd reason. Where they're thinner also appears to be chunks of rust that if I chipped it away, they might end up even thinner yet. It's really weird corrosion that makes me wonder if AE 077's somehow let water get into that air space between rotor and lugnut. It's really disappointing that the eBay hubs are that crappy. I'll give pounding out the studs another try tomorrow. The hub still turns freely so maybe all my hammering didn't hurt it. Quote Link to comment Share on other sites More sharing options...

I've never had them not come loose with enough persuasion. A bit of rust penetrating lubricant might not be a bad idea either. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted December 27, 2009 Author Report Share Posted December 27, 2009 ... WHICH CAR IS THIS? It's the 94 convertible. Yeah, I've replaced around 4 studs on the '88 and it was no problem pounding them out, but this hub seems extra difficult and extra rusty.

Fill up a small tub full of gasoline and submerge the stud end of the hub till you're a little higher up than the studs. What could it hurt? Worst case you'll need a new hub anyway.

It's probably because of the galvanic corrosion or reaction of two dissimilar metals. The steel studs and the aluminum wheel. X2 on the studs though regarding removal. Try a air hammer. Loud but effective. Ebay + most auto parts they offer = this very shortly: Quote Link to comment Share on other sites More sharing options...
Crazy K Posted December 27, 2009 Report Share Posted December 27, 2009 Gnat... would you like to BUY a good used bearing? it is probably bad from before you bought the car... which means you need to check the other 3 bearings soon... actually... do this: go to AUTOZONE. they should have a stud removal press in their rental tool catalog. try that rather than a hammer, as a hammer can cause bearing damage..........

mfewtrail Posted December 27, 2009 Report Share Posted December 27, 2009 Not a ton of difference in the rockauto price, but amazon.com has that Timken hub for $105ish. http://www.amazon.com/Timken-512004-Axle-Bearing-Assembly/dp/B000BZABIU Quote Link to comment Share on other sites More sharing options...

IRONDOG442 Posted December 27, 2009 Report Share Posted December 27, 2009 TIMKEN is not, that's the only domestic bearing manufacturer I know of. I was speaking more specifically to China as they had been mentioned before. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted December 27, 2009 Report Share Posted December 27, 2009 Timken and SKF. Which alot of the times SKF bearings are made by Timken. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted December 27, 2009 Author Report Share Posted December 27, 2009 Gnat... would you like to BUY a good used bearing? it is probably bad from before you bought the car... which means you need to check the other 3 bearings soon... Yeah, the other side torqued without incident, so I'm not going to worry about it till a stud breaks. I hadn't gotten around to the fronts yet though. If you have one you're sure is good, I'd certainly be interested. I sprayed more WD40 and let it soak during the morning, then gave it another go this afternoon. I tried my Kent Moore balljoint removal tool which DID work fine to remove a stud from my spare front hub, but it didn't work on the rear hub. I also found a metal pipe and put it behind the stud to give leverage while pounding on the top of the stud. That didn't help. I tried heating the surrounding area with a torch and then using a piece of ice on the stud only to force it to contract, then tried both the balljoint tool and pounding. It hasn't budged even a 10th of a millimeter. actually... do this: go to AUTOZONE. they should have a stud removal press in their rental tool catalog. try that rather than a hammer, as a hammer can cause bearing damage.......... What's the stud removal press look like? Does it look anything like my balljoint removal tool? I've attached a couple pics of it. It did leave a pretty good impression in the top of what's left of the stud. UPDATE: Went to Harbor Freight and picked up a 3lb sledge. The top of the broken off stud is now mashed like a mushroom, but it hasn't even budged a millimeter. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted December 27, 2009 Report Share Posted December 27, 2009 I know I do, in fact i should have 3 spared. I will try to find it. Face it, you're my favorite 98 pound weakling, but you're still a 98 pound weakling... unless you gained a pound! I think the old bearing is done anyhow, as the hammering will have compromised the bearing. Quote Link to comment Share on other sites More sharing options...
