im replacing my trans with a used 4.05 trans .. the stock trans i have only has 10k if that on the throw out bearing its a gm oem one would it be fine to reuse this one ??

Ya that's pretty much brand new I'd use that if I was you for sure. I'd just take a look at it and see how it spins

justabalt

yea gm installed it after i blew my first trans so they replaced my clutch and thrown out bearing when i brought them my ky3 clutch to them so i didnt have to do it but now i have a 4.05 i wanna install in it to hold the power

KMO43

So youre gonna run the lnf bearing with 10000 on it?

get a new one no if ands or buts..... its used and should not be re used.

it's a bearing... everyone will say to replace it for sure because that's what the how-to says... buy one and use your judgement. if the bearing spins freely it's probably OK with that low mileage. if you question it at all replace it. GM is good about taking parts back that aren't used.

I say to replace it because they are wear and tear items. If your upgrading the clutch put a new one in. I work on these cars everyday and do clutches all the time. It's a cheap part replace it

I wouldn't replace it unless that whole ordeal with the faulty TOB's is done.

i dont think there is a whole ordeal with faulty throw out bearings. atleast not to the extent people make it out to be. im sure there is SOME out there but 95% of the failures i have seen come into the shop are ALL due to installation error thats being blamed on gm for "junk parts"

the last "faulty" throw out bearing that came into the shop ended up costing the guy a case because he didnt put it on correctly. also im pretty sure CED is no longer warrentying them unless they are put on by a profressional shop or dealership.

What exactly are people doing wrong to cause them to fail.

Where'd u find a used 4.05?

Agreed on both counts. There's not a lot of "faulty" bearings, just a lot of faulty installs.

I couldn't bring myself to re-use one, it's such a cheap part and it requires dropping the trans if you have an issue, I'd rather put in a new one and know that it's good until I have to remove the trans again.

Out of all the clutch jobs on balts I've done over the years, the ONLY TOB I've ever seen fail was, believe it or not, actually on my own car.

idk where to start here

1. not installing it and torqing everything properly - un even torque can cause the tob to tilt and eventually unseat partially

2. not bleeding the clutch good enough - this can cause **** poor engagment and the potential to over extend the tob

3. not making sure its seated to the case - this cause cause the seals to rip and the tob to be tilted in a way that wont cause proper engagment.

4. trying to suck the transmission together with bolts without 100% confidence everythings aligned(the t rans should slide right in if its done right). this causes im proper compression of the tob EVEN if the trans sucks up all the way. this also can cause further damage to the clutch, transmission etc etc.

5. thinking everything line up and trying to force it - self explanitory

6. not buying a new clutch pipe or distribution block - usually this isnt an issue but what i have found is a lot of people can seem to screw the clutch pipe into the tob for whatever reason and strip and and say **** it and it leaks. distribution block is just good to replace so new seals and clips are in place.

7. stripping or drilling the case improerly and either not putting a helicoil in or just not drilling in the right location - had this one happen to me recently and it caused the throw out bearing to unseat and compress at al angle and destroyed itself

8. using the wrong length bolts - causes the tod to unseat or ive seen a guy poke through the case

9. not checking all your corresponding components. THIS IS VERY CRUCIAL!!!!!!!!!! guys are such cheap asses they refuse to purchase a 15 dollar distribution block, 8 dollar clutch pipe and 60 dollar tob... i mean wtf..... things wear out and sometimes prematurely. some people get lucky nothing ever happens. another thing to check is the clutch master at the firewall....... being messed up or not having the proper clutch stop will cause over extensions as well.

10. improper tools and this is self explaintory for all the reasons above at some point.

11. resurfacing the flywheel... i mean wtf... i get that this si a common thing but for readily available cheap parts just buy a new one.... some machinests have to take out so much material it puts the flywheel out of tolerence.


i mean theres are just some of the ones i have seen. im almost entirely convinced most of the ones on here are nto faulty either. dont get me wrong. IT CAN HAPPEN. my theory here is 8 out of 10 fauly throw out bearings are due to improper install. its the nature of a mass produced part but i mean seriously guys have 2-4 go right in a row and they thing its gms "piece of ****" parts? no


sorry for this little immature rant BUT at the end of the day i keep telling guys this. TAKE IT TO A PROFFESIONAL IF YOU HAVE ANY DOUBTS IN YOUR MIND ABOUT DOING THE JOB. that extra money you saved trying to diy or not buying your parts from a really good place will usually end up being put into the car because of something going wrong. the cobalt clutch is not for first timers imho either. is it hard? no but if your on your back it sure makes it a 100x's more difficult.

I've said this before to people and they will only blame the GM parts. I've done 10+ clutch jobs, only had ONE new TOB fail and it was my fault for not bolting it down properly, it was the first one I did, I broke one of the bolts, figured it couldn't move with the other two installed, ended up failing the TOB during bleeding. Took it out, got it parts warrantied thankfully but once I removed the broken bolt and installed a new proper size replacement one, it was perfect for years after that.

I'm looking to get my clutch replaced and I can't seem to find that distribution block thing, anyone know a part number or where I can get one?

Different sources refer to it as different things, but here's what you're looking for.
