Why do these things fail all the time and why are they so fucking expensive?

How is this any harder to make than the motor off a $50 drill press?

This. What's even worse, that in many cases the parts actually cost peanuts, but is mounted in a contraption where you cant just replace the electronics.
>>
The bearings blew up on my alternator.

Toyota quoted me $450 for a new one
Part source $265 for a rebuilt
A local store manned by poo in loo quoted me $110 for who knows what

There's a auto wrecker nearby, should I even bother calling them?

>Not using dorman parts with a lifetime warranty

The entire front end on my old dodge was done with dorman parts. Didn't last long but I was able to beat the hell out of it wheeling and replace them for free. Eventually rebuilding the front end took less than a couple hours.

Vatozone alternators have lifetime warranties. For that matter, so do their steering and suspension parts. Pretty much all their parts, except wheel bearings.

Idk but it's pretty gay thinking new anons are as stupid as /o/.

Found a used alternator from a local wreck, $63. I'm thinking the poo in loo shop is also quoting me a used one.

Idk what to do, or buy the rebuilt with warranty.
>>
>>15243963
>fail all the time
>???

If you keep a car long enough, you will need a new water pump/thermostat, new alternator, new front brake calipers, new spark plugs, and even a new fuel pump. Even long life parts wear out.

I can't seem to get to the last plug, so the dealer will manage to victimize me for a set of platinum plugs. It's one of those laughable situations where parts cost one penny, but the labor costs one dollar. Scale it up and that's plugs in my car. Did the manufacturer do things like that to build in service profits for their dealer chain? That's the real question instead of "why do alternators fail all the time?".....
>>
>>15244271

Let me break it down for you

If the alternator is in an easy to access spot for changing
>Buy the reman with the warranty

If the alternator is going to be a PITA to change
>Throw your hard earned sheckles at the expensive model
>>
>>15244288
The alternator is right at the front held by 2 bolts, I took it off b4 when I changed my waterpump.

The remanufactured with warrant is $265, the ones off crash damaged cars are the cheap ones, and the fucking japan made shit is $450 fuck that.

The fuck are you doing that you keep needing to replace them? Seriously, I've never had an alternator go on anything I've owned. I had to replace the voltage regulator on my S10, but that's it.
>>
>>15244397

Maybe he has a big aftermarket stereo blasting dat bass and sucking power 24/7.
>>
>>15243934
You know Toyota and other companies sell the bearings so you can rebuild the current one it's not hard you can probably find a diagram online
>>
>>15244397
It's a Toyota so most likely just the bearings they constantly go bad on the 4 cylinders
>>
>>15243934
It's usually the brushes that fail.

Cool thing if you have an older ford with a voltage regulator bolted to the back of it is you can just pop off the regulator and service the brushes and replace the regulator while you're in there without having to tear down the alternator.
>>
>>15244497
Don't got time or the tools to push out and press in a bearing.

Just got a new job I start on monday and have to drive 60km each way.
>>
Tensioning the belt seems to have stopped the grinding noise for now. I loosened the belt and grabbed the hub and it was moving up and down freely and wobbling side to side.

Hopefully this shit holds up on my drive out to pick up a replacement.
>>
>>15243934
because the turbine blades and components have tight tolerances.
>>
Just see if you can get one on rock auto. They usually have core charges with these things too

Take it to the store and get it rebuilt by the poo, it'll be fine for another 20 years.

Shit, how hard is it to press out some bearings, take them to the nearest bearing house, buy new and press them in?

Whiny bitches, lrn2workoncars
>>
I went with poo in the loo, the stupid auto wreckers apparently didn't even keep the parts at the wrecking yard and needed 3 days to get it.

I think my alternator was probably ok because it spun smoothly, but the hub wobbled all over the place which makes me think the nut that holds the hub on probably came loose. Didn't realize this possibility until I saw the replacement because the hub on mine was capped with a rubber plug which hides the nut.

Well I said fuck it and replaced it anyways since they drove the replacement in from the supplier while I was pulling out the old one which turned out to be a shitty denso unit. Can't say the replacement is any better, it's some no name SAP branded remanufacture.

$110 all in all which is ok as long as it lasts me until I dump this car.

I do all my own shit, but I don't find these things nearly as prone to failure as you make them sound. My jeep has 143k miles and I barely changed the stock waterpump 3k miles ago and that was just because I was replacing the fan and fan relay so I figured I'd do the whole cooling system while I had it apart.
>>
>>15244926

Holy shit, that was eight years ago? I've been here too long.
>>
>>15244500
...so rebuild the alternator? They aren't that complicated.
>>
>>15245550
>spark plugs
>being difficult to change
That depends on the car. #11 and 12 on a BMW M73 are a stone bitch, as is #1 and 3 on a transverse EcoBoost V6.

But yes, some are stupid easy. (BMW V8, for example - M62)
>>
>>15246238
A lot of people don't realize how easy it is to chang plugs when you have the right equipment or do simple things like removing the valvecovers.
>>
>>15243934
>fail all the time

The alternator on my 245DL survived 32 years of abuse and its replacement (installed at home) cost $45 and came with a 5 year-warranty.
>>

poor detected.
>>
>>15246807
Did you not read the thread, $100-$200 gets you some shady rebuilt part from some indians. $200 -$400 gets you brand name rebuilt with warranty and $450 gets you a new one from toyota.

I just bought an alternator from the stealership, its not worth spending so much time on alternators that just die and die over again get yourself a better one if it continues to die dont be a dumb nigger
>>
>>15243934
>why are they so expensive
copper

it's usually just the regulator that breaks, not the actual mechanical aspects of the alternator
>>
>>15248129
Did you not read the thread? Go shop somewhere that isn't Goldstein Shekelberg's Auto Parts Emporium and you can get a brand new alternator with warranty for <$100
>>
>>15244002
Just replace the bearings then you inbred. Hardly fucking rocket surgery
>>
>>15248129
Must be driving some special snowflake.
Even my special snow flake OE alternators are sub $300.
If you go to the dealer of course they'll be double or triple the price of a normal one.

>>15248374
You cannot in keknada, everything is owned by goldsteins and shekelbergs. 95% of our land still belongs to the queen of england.

Go to fucking Lordco and ask them for an alternator. I got a brand new 70A unit for my RX7 from them a couple years ago for $85, tax included. Still works perfectly fine today.

Yeah if you didn't realize everything in canada is shipped into vancouver and distributed by rail and between BC and here a premium gets added. Also the price of shit nearly doubled from a couple of years ago.

You skipped a lot of things right there with the oversimplified way you worded things. While a bit worse, it would be like saying "why do they charge so much? All he did was wash his hands, pull the bullet out, shove the bones back together, pinch the wound shut, and for all that he wanted 18,000 USA dollars? It's UNregulated capitalism. Charge what the market will bear.

to be honest that's the only thing that could fail except maybe the bearing
